Posted 29 June 2014 - 03:28 PM

I have been a faithful KWA owner for 5 years since I started playing airsoft. I own two m4a1, two commandos, one sr12, one sr10, one mod1 and two atp. For years I have used the same tech to repair and upgrade my guns, who frequently makes posts on this forum. I never had a problem with any of his upgrades or repairs. My guns had always performed flawlessly. Recently, because this tech had gotten extremely busy with several businesses I decided to use Vanevery to work on and upgrade my guns. Vanevery makes a lot of posts on this as well as other forums talking about modifications and methods. I am not going to bore you with all the back and forth I have had regarding this, but more or less get to the bottom line. These are facts and truths. The first gun he worked on was my sr12 that had been upgraded previously. After the Vanevery upgrade, the first time I fired it, is was misfiring every 5th shot or so. He corrected this. The next time I used it in a game it stopped firing due to a blown mosfet, he fixed it. The very next time I played with it in a game it stopped working because of a blown mosfet. The next time I played with it it blew a piston with less than 2000 rounds fired on that piston. After I cancelled our business, it was returned with a new piston, however it now has a terrible power burst in the semi mode and greatly misfires. I will admit that the gun shot great when it was working, not so much now. During these issues with the sr12 I had my primary m4 a1 carbine go down because I put in a zci motor. This gun was shooting 23 rps with a 370 fps using .28 bbs. I sent it to Vanevery for a upgrade and when I received it back the first time I fired maybe 15 shots and it stopped. He fixed it and sent me a pic of a burnt wire. He also pre warned me that now it was only shooting 16 rps and it shot 370 with .28 bbs, NOT a upgrade from the performance prior. When I received it after i had concluded our business it sounded terrible, shot 16 rps. I sent it to a reputable tech for review and he could only describe the work to my gun as a "hack job". In a nutshell this tech said I would be better off buying a new gun rather than repairing this one after the Vanevery work. My primary was ruined! I then gave Vanevery my SR 10, second m4a1 and my mod 1 for upgrade. I received these guns back on a Thursday before we had a big Op at Ballahack. When testing the guns the second carbine misfired so I did not take it to Ballahack. In the Op my Sr10 went down due to the motor. I was told by Vanevery that he put brand new motors in all of these guns, this was total bs, the battery went south on the first Op and three techs since then confirmed it was not new. my sons Mod1 also went down as well so both of us were forced to use our pistols on a OP I paid 100 bucks for. This was the last straw! I asked for my money back of course and he responded saying there were "no refunds", how convenient. You may be asking, Why did you keep giving him your guns if you were not satisfied with the work? All of this was overlapping and I believed he would make it right with his so called warranty. With EVERY single gun I gave him going down or not working properly the very next time I used it, something had to be wrong so I concluded our business relationship. What good is a warranty if every time you drive your car off the lot you have to take it back, at some point you have to say ENOUGH. Vanevery took 1150$ UP FRONT for this and I have asked for a portion of this back to no avail. Please be diligent in your review of techs and don't rely on on pretty long 5 page posts to make your decision.

I will respond to this.
I am very busy with work this week, so it may be a few days before I have a chance to respond.
I will make a few points, now.

I have worked on airsoft guns for five years.
I have done this professionally for two years.
In the two years that I have done this professionally, I have never had so much as one customer ever request Warranty Service or ever make a complaint about my work.
I go out of my way to:
- Build the best performing airsoft guns.
- Build the most durable airsoft guns.
- Take care of my customers with clear and prompt communication, extended warranties and freebies.
- I take pride in my work and offer the best Customer Service in the business.
Dru is my first and only Nightmare Customer to date.

The first gun I was initially contracted for was the SR12.
I will mainly discuss this gun in this post for I believe this stated experience will allow any reasonable person to connect the dots as to how the other gun projects went and dealing with Dru.
Dru paid me $175.00 for:
- Fully Tuned Gun
- All Part included
- Extended Warranty on all Parts and Labor.
(Initial extension was 90 days I think. As more guns were added, I gave Dru a six month Warranty on all Guns, including the SR12. This Warranty covered all parts and labor).
- I always throw in extras for first time customers.
In this case Dru received:
1. One Brand new Bag of GoldenBall .30's.
2. One Brand New Bag of WE .36's.
3. Two 11.1v/3000mah /15C Li-po Batteries.
4. Li-po Safe Bag.
($100.00 value just in extras).

The performance of this gun was unbelievable.
My best tech work of any DMR I have ever built for a customer.
The Gun would shoot and light up a target effortlessly at 400' and had a range of over 450'.
This with a 509mm barrel no less to start, and then I installed a 455mm with even better results.
Dru endlessly complimented me on the performance of this gun and as a result, for over two months and in every communication we had, Dru either directly asked, suggested, or referenced that I needed to work on all of his guns.
I was very busy with work and continuously declined to do so, but at some point I decided it might be a fun project, so I accepted the job.
Not only that, I offered Dru a financial bargain deal.
I offered that if Dru would pay the complete price for the Tech work of three guns up front, I would do the fourth one for FREE.
Dru accepted this deal.

SR12:
I put 2000 rounds through this gun in testing before putting it back in Dru's hands to ensure everything in the gun was working properly. I told him "go talk some trash to some Polar Star Owners for there is no way they will out shoot you".
Dru texted me within 24hrs stating there was a problem with the gun.
He stated it was not feeding correctly.
I told him I would drive to his local field that weekend, shoot the gun in front of him, and if there was any problem, I would fix it on the spot or install a new Barrel Group( Complete Inner Barrel/Hop-up assembly) right there.
Knowing there was no problem with the gun, I made the drive and brought four different Barrel Groups with me just in case.

So, I get to his local field, we find an area of the field to test at, and I shoot his gun.
I used my own KWA magazines to start, thinking it may be possible one of his magazines may have a problem.
Mag One: KWA High Cap with Crossman .20's.
Result: No feeding Issues.
Mag two: KWA High Cap with Elite Force .28's.
Result, no feeding Issues.
Mag Three KWA k120 MIdCap with WE .36's
Result: No feeding Issues.

I then requested to use his magazines with the Ammo he was having Issues with.
The ammo he was using was GoldenBall.30's, that I gave him complimentary.
Upon shooting I noticed that every 5th or 6th shot was a flyer, or misfeed.
The Hop-up Unit was turned all the way off when I began shooting.
I then turned the Hop-up dial ever so slighty to increase Hop, and the gun then fed and shot perfectly fine.
I then turned to Dru and said: "You know, all I did was add Hop".
He turned to me and said: "Well you said to shoot it with the Hop-up all the way off".
I replied: "Start off with the Hop-up all the way off, then add Hop accordingly.

Even though there was absolutely nothing wrong with the gun, I then offered for Dru to test shoot each and every Barrel Group I brought with me. He did, and that is when the 455mm Inner Brrel was installed for he liked the shooting performance of this Barrel Group best.

A week goes by and I get a call from Dru.
He stated that he went to a game.
The gun shot  great all day and at the end of the day it just stopped firing.
No power whatsoever.

I got the gun back, looked over the wiring.
There was a tear at the Connector, XT60 Battery Connector.
The funny thing is, when the gun first came to and before I ever worked on it, there was an identical tear just like it. I had already initially cut off the old XT60 Connector that was installed by another Tech and installed a new one at the start of this project. Now, I had to do the exact same thing two weeks later.
Another Funny thing is that I heavily reinforce the solder connections.
After Heat Shrinking the connections, I insulate the connections with electrical tape to distribute the force, This is to protect the solder connections form those who use overly aggressive force when removing a battery. Some people are just rough with wiring.
Dru is the most overly aggressive person I have ever seen handle wiring and remove a battery.
I would describe Dru as ripping, not removing, an airsoft battery from its respective connectors and gun.
I don't use fuses, so I believe the tear at this Connector resulted in the Mosfet shorting out.
So, I replaced the xt60 Connector, replaced the Mosfet, and the gun was working just fine again.
I returned the gun to Dru, problem solved.

I now get another call two weeks later.
He stated the gun has lost all power, as before.
He stated he had a game that weekend and needed his gun.
I said I would personally deliver this gun to him at the field of the game that morning, and I did.
I got the gun back from Dru, looked over the wiring, and noticed the Signal Wire connection at the Mosfet was completely torn. This in turn shorted out the Mosfet.
I then replaced the Mosfet with another brand new one.
The gun then worked perfectly fine again.

Note:
I drove to Greensboro to personally deliver the gun to Dru so that he would have it by the game planned for that weekend. Upon handing Dru the gun, he then ripped the Supply wire out from its corresponding Connectors right in front of me while attempting to switch out the battery.
I had to drive all over Greensboro to find a Home Depot and get the tools I needed to resolve the situation:
1. Long Screwdriver
2. Heat Shrink.
3. Lighter.
I arrived back at the field and solved this issue as well.

I now get a call a week later stating the gun went down and he thought it was the Piston.
Upon opening the gun, It did in fact prove to be a Blown Piston.
The Piston was a Raptor 14 tooth Piston with an all steel rack.
I have this Piston in other guns, one of which is a Customer's gun, and have never had an issue with these Pistons.
I replaced the Piston with a Lonex Red.

Summary:
- 4 Warranty Service Calls.
- Three of which were User Misuse and Abuse for:
A. Not knowing how to operate a Hop-up Unit.
B. Not being able to touch wiring without tearing or ripping something.
- The Piston blowing was no one's fault. That is just airsoft QC.
- Cost: Parts alone were over $350.00 when you include the Warranty Service calls for Mosfets.
Was paid $175.00. You do the math.

Conclusion:
- Dru's SR12 was under Warranty and he chose to breach and consequently terminate our contract by sending some others guns, that I had just begun working on but only halfway finished but had yet to complete, to another Tech during our contract period.This so Dru could use some of these gun at an Event.
- Dru has sent me many emails since our business relationship ended asking for refunds and also warranty repair service. Having made it crystal clear to Dru that:
A. Dru Breached the contract, not me.
B. Dru's guns were under warranty and I had offered multiple times to honor that despite all of this nonsense he was putting me through, yet he declined.
C. The Service Agreement in my Term and Conditions specifically makes it clear that once monies are exchanged, there are no refunds, at any time, for any reason.
This is actually the first statute listed in the Terms of Service Agreement.
D. I am in no way Liable for what another Tech does to his guns.

One last thing.
When Dru and I met so I could return to him the remaining guns I had of his in my possession, here is how that went:
- Dru about made me drop one of the guns I was carrying in a rush to shake my hand.
- Dru stated that all three guns that I had previously worked on and gave to him to use at the Event, he had inspected by another Tech.
- He then stated that of the three guns the Tech looked at, the only thing they could find wrong was a bad motor. This was a brand new ZCI High Speed Neo Magnet Motor, which by the way was working perfectly not only in my testing, but when I dry fired each gun right in front of Dru when I gave Dru those Guns back initially. Dru then stated, there is no way that was your fault.
-Dru then stated that the Tech asked who was in fact the Tech that worked on these guns?
Dru told them I had been the one. Dru then stated that this Tech then told him to tell me what a great job I had done on these guns.
- Dru's last remarks to me in this meeting were: "Don't worry, I have no intention of trying to smear your name". He has also made this statement multiple times to me in email communications over the preceding weeks as he was trying to shake me down for money. I have those emails saved.




I will reply further when I have the time.

WOW.  I actually read that whole thing.  I know they say there are 2 sides to every story, and the truth lies somewhere in the middle.  Well from this story I lean towards Vanevery's side due to what he wrote.  I know you cant make everyone happy but from what you said above it seems like you tried everything you can.  You really went out of your way here.  Remember airsoft guns have moving parts.  Parts in which can fail due to wear, product or even user error.  

You say your going to reply further later, well i think you covered it all.  I cant imagine there being any more to say.

I feel like this is turning into a jury situation right now, and it seems a little immature. However, I do think I need to agree with Icurblud on this one. I've had some conversation (not much, but some) with Vanevery regarding my DMR build. In none of his statements did he EVER sound under qualified. I have no experience with you Dru, but from what little I know of Vanevery, it really makes me lean towards his side of the story. It sounds like there were things that were clearly stated in the contract that you didn't abide to. Almost like you didn't read it. I can understand your frustration, but his story just sounds a little more accurate. Just my two cents.

I read the whole thing too... Don't have my contacts in so my eyes are starting to hurt XD But I would have to side with Vanevery on this one as well. He went out of his way to have your guns delivered to you on game day, which isn't an easy thing to do, depending on where he lives and where your local field is. You did sign a contract, and whether or not it was drafted by an attorney, if you took this case to court, you would lose just by merely breaching your contract. It is a legal document and from what Vanevery is stating, you breached it, went back on it, and then asked for a refund that was stated in the contract as not possible. So while you seem to have had a problem, I think you caused the bulk of it. Vanevery did everything he could, as well as prove to you the guns were working fine by demonstrating in front of you that all the guns fired. So I'm gonna have to take Vanevery's side on this one. He seems to know a lot about the guns he's worked on just by looking at threads he's commented on. Added to that, nobody else has complained about his work.

Fellow airsofters, I appreciate everyone's opinion on this matter. First and foremost there was no contract signed or otherwise, nor did I agree to any terms or conditions. I also have no intention of using any legal system regarding this. In my post I was trying to not bore you with more detail than was needed and just talk specifically about the quality of work I received from Vanevery. Vanevery wants to talk about what he said or I said which has absolutely nothing to do with the quality of work, the bottom line is every single time I got a gun back from him it failed the first time I used it in a OP, not the second time, or the third time or the forth time, but the first time. In the four years prior working with another tech who upgraded my guns, I never had this problem. A big part of why I stopped using Vanevery was because of his continued written insults which he still continues to do. When my sr10 and my Mod1 went down at the OP on Saturday when I had just picked them up from him on the Thursday before I wrote him saying enough is enough and I may want some money back. Saying I am trying to shake him down is ludicrous, I was and still am a unhappy customer. He wrote me one of his war in peace emails telling me the first three times he repaired my sr12 it was "user error" and I am a customer who "doesn't listen", and of course no refund partial or otherwise. He accuses me of being aggressive with the wiring and the battery and being the most aggressive he has ever seen. This is a outright lie! I never had any problems with my batteries or connections the four years prior and I have always used XT60! As far as his time on the road, he drove to Greensboro once, I drove and met him half way three times, and drove to his place of business at least three times which is a two hour drive for me. I guess its easy for him to save face and blame it on the customer. He mentions all the ancillary items he gave me and places a value on them as if it had anything to do with the quality of his work. I did not ask for batteries, I did not ask bbs, I did not ask for a sh*t a** lipo bag, all I wanted was a gun that worked. Speaking of batteries I gave him one of my 50$ Bol 11.1 lipo batteries so he could test etc the guns. He admittedly Fried it and did not offer to replace it. One very important thing that he conveniently left out is that when I got my sr12 back the final time it has a really bad power burst in the semi mode which is the only mode it has. So bad in fact that when I used it in a Op two weeks ago it went from a power burst to now just shooting full auto and misfiring, I guess that's end user error as well.

My primary m4a1 was the next he so called upgraded, I explained the before and after performance in my post above. When I got it back the last time it sounded so bad I sent it to a reputable tech. What he found was the sponge Vanevery put in the spring degraded and totally trashed the gear box. There so many other problems with that gun including the wiring, soldering etc and what vanevery did to it that I will be spending at least 300$ to correct his work. As far as the "new motor" he claims he put in, the tech that looked at it said he has seen motors that have shot 100,000 rounds though it that didn't look that bad. I don't know what this means but over half of the motor brushes were worn down. Guys, let me ask you, warranty or not, would you keep going through this. I have sold surgical devices for over 20 years, how many times would a surgeon buy my device if he had to keep sending it back for a problem? He doesn't give a sh*t about a warranty he just wants what he purchased to work, period. In fact, he would ask for his money back. And I certainly would not fall back on some fictitious contract he never signed or looked at and try to posture him with bs legal speak like "breach" etc. Most legit businesses do not require money up front to operate because they completely want to make sure the customer got what he paid for.

I picked my sr10 up on a Thursday before my Op on Saturday. In the Op the gun went down as I should have guessed. When it was reviewed by another tech he told me the zci motor went bad. A new zci motor going bad on the first Op with less than 1000 rounds shot with it! He also confirmed this was not a new motor, it was greatly used, scratched and had marker markings on it. Sure, he dry fired it in the parking lot, big deal. Admittedly he said he did not field test the gun. That's for sure, because with my hop up all the way off the bbs were rising so bad you couldn't hit anything. Oh, that's right, I don't know how to use a hop up! what kind of bs was that. When the tech first opened the gear box he asked me " did Vanevery mean to leave all the screws out of the top rail to the gear box", I looked at it said I didn't know. I asked Vanevery this and he denied it. I told him the name of the shop and tech and he could him he didn't believe me. I guess that's end user error or abuse as well.

My other two guns also have issues, I just haven't had time to break into them yet.

In closing on this, as you all have opinions, these are mine and my experience. Everything I have said is a fact and I can back it up. I am focused on the quality of work so maybe others may not have to go through this, he can talk about us shaking hands, or what I said, or whatever, that's not the issue. Also, I am not looking for any of you to pick a side, I could care less.

Now I'm seeing where Pyro is saying that this is turning into a jury situation.. It seems like you guys are each trying to state your case against the other as if this were a trial.. I think what should be done right now, rather than to provoke further arguing from Dru and Vanevery as to who was right or who was wrong, this whole thing should just be dropped. Alright, Vanevery has a disgruntled customer, and Dru is unsatisfied with the work he received. So Dru, don't come back to Vanevery for tech work. Either go back to the tech you were using before, or the tech that you took the guns to after Vanevery's work. Vanevery, I advise that you drop the subject as well. Both cases have been stated, and it seems like it's about to turn into an argument which shouldn't be on the KWA forum. This is a helpful place, and Dru your experience with Vanevery is noted. Rather than continue bashing each other in whatever way you choose, it would probably just be best that you both drop the subject, move on, and cease contact. Vanevery has stated there won't be a refund for any reason, so I'm sorry Dru, but it's not going to do any good if you try to continue to get some money back. If I were him, arguing to try and get some money back would make me less inclined to give any kind of refund. I'm just trying to play ref here and eliminate the fighting and arguing or whatever you call this whole scenario. So again, I strongly advise you both just go your separate ways and leave it where it is. Capeesh?

hey, stealth task force, how many Kwa weapons do you own? Do you take pride in them? How many people are on your team? Are you the commander of your team? The only reason I am on this website is because my loyalty to Kwa, who asked you to be a ref or moderate this.

I got my first CQR Mod 2 a couple months ago. Of course I take pride in it. I'm not part of a team, so therefore no. And nobody had to ask me to be ref or moderate this. I am doing so to prevent further argument because this forum isn't a place to host petty arguments such as this. You shared your opinion, which we all see. You shared your experience, but you seem to be the only one with an experience like this. This forum is for opinions (which you shared), experiences (which you also shared), help on subjects (which you didn't share), and definitely NOT for arguments (which you have shared). So if you would like to make pot shots at me for trying to prevent further arguments, go ahead. I do not give a D*MN and I can VERY EASILY ask gcw to lock this thread if it continues because I'm sure he agrees with me on the fact this is not the place for arguments about business. No one had to ask me to ref or moderate this. I felt it was my duty as another user of this forum to prevent arguments and fights. You shared your opinion on this matter, Vanevery shared his, DROP THE D*AMN THING ALREADY!! I'm 16 and know when to end something. So as I have picked up, you're a father so I would hope you know when to end it as well.

Let's all take a step back.  I will not allow this to degrade into a pissing match.  Opinions are just that, opinions.  You are all welcome to them, but they are not necessarily founded in fact.

If you are wondering why I am writing this it's because I have deleted some content considered inflammatory.  And if need be I will close the thread.

At the risk of fanning the flame, Dru, can you post proof of the workmanship beyond hearsay?  Like, pictures of the inside of the gearbox?  Presumably, since they failed the reasons should be apparent and perhaps it would help settle this whole thing.  Just a thought.  Maybe your tech can take pictures and send them to you to post?

That's a good idea. It just occurred to me that since we all have our own opinions, maybe one tech would think a gear box is shredded when it might not be so bad. So pictures could be a very good thing, because that would help eliminate hearsay as Rex so eloquently said.

This is another reason KWA does not condone buying, selling or services on this forum. I'm close to closing this thread, but will allow Dru to post pictures, if in fact they exist. If I do not see something reputable as far as proof, this will be closed.

Thank you,

KingSize

I have been following this thread for a couple of days now and have read both sides of the argument.  I feel that there are many things that went wrong with BOTH parties involved.  I am not resting blame on any single person though since these things happen more often than not even with the best of intentions.  And as Kingsize already mentioned this is the reason we do not permit any sale transactions to take place on our forums whether it’s  product or service. With that said I will interject with some of my findings.

There are always 3 sides to any given story which are “yours, mine and a grey shade of overlapping truth.”  I will give you to the best of my abilities, a non-biased and objective findings.  Drudog contacted me about a week ago and asked me to take a look at a gun that was returned to him after some modifications had been done.  Now I used to work on his guns on and off over a period of 4 years and believe me when I say he owns probably more KWA guns than I do.  :)  Over the years I have done many spring upgrades, maintenance, and repairs on all his guns so I am very familiar with all of his guns.  I know what they looked like and how they performed when it left my work bench.  But I have not been able to do any work for him for the last 6 months or so because I don't do this for a living and work that pays the bills occupy most of my time. :)

On the other side of this I have become very familiar with Vanevery's work over many years from all of his very interesting and detailed posts of his upgrades and modifications.   From his posts he appears to me to be a very technically knowledgeable person when it comes to AEGs.  I feel that he is not only very insightful but also very helpful with other members of this forum.  We, admins and mods alike, always appreciated his input and help around the forums.


Now with that said let me state that although I am a moderator on this forum I am in no way an official KWA employee and what I am about to post is not with their blessing.  I will be objective in my findings and I don't do this for a living and is a hobby for me that I have enjoyed for almost 10 years.  There's nothing that will take fun out of something faster than doing it for a living.  Which is why I never went in to this business.  :)


NOW THESE ARE MY FINDINGS:   You can make your own conclusions.


MOTOR: The first thing I noticed when I opened the base plate of the pistol grip.
I don't know what is going on here.  There were electrical tape rolled up to push the motor into to grip. This should have not been done since it can hinder motor height adjustment and free movement.  If the motor was out of spec and was not a good fit the customer should have been notified with alternatives.
Posted Image

The actual motor.  I have read vanevery's report and also his earlier response posts that this was a brand new "ZCI High speed motor."  I have found that the brushes were worn down by more than half and it looked to be in a bad shape.  Can't say if this is a QC issue since this was supposedly brand new but one thing to note is that this high speed motor was used in this build to pull a Madbull M/SP140 which is more like a standard M150 spring.  Most if not all high speed motors are rated to effectively pull M120 and "maybe M130" spring at most.  I think this motor was a very poor choice for this setup with such a heavy spring.  The excessive load on this motor (beyond what it was capable of) is probably the reason the burshes were destroyed and the motor now probably damaged.  This gun was shooting at around 16bps (11.1V 2200mah lipo)  at 380fps with 0.20g bb's when I tested before disassembly.  The trigger response was very slow even with a "mosfet" and an XT60 connector.  It sounded very scratchy as if the motor height was not set correctly and I couldn't adjust it to sound smooth.  This is probably from the tape in the grip and a bad shimming on the bevel gear.
Posted ImagePosted Image


WIRING: I read a report sent to drudog about new wiring that was installed on this M4A1 and I found heat shrink and electrical tape around the wires that go in the pistol grip for the motor. The entire length of the wiring should have been replaced since the tape and electrical tape can make the wiring too thick in the pistol grip for proper motor alignment and height.  Not to mention the electrical tape can come off exposing the strip in the wiring that it was covering and short out the electrical. The wiring was not replaced as the report indicated.
Posted Image

The new soldering on the trigger switch assembly.  I think there was too much solder used.  The excess solder could make contact with the gearbox shell and cause a short.  
Posted Image

The wiring leading to the mosfet and battery look ok but I would have used a smaller gauge (22AWG) wiring for the fet signal wire.  It would have set nicer inside the gearbox that is already very limited in space.  There was a lot of heat shrink around the bullet connectors and coupled with a thicker signal wire had some trouble pulling it out of upper receiver opening for disassembly.  
Posted Image

MOSFET: This was a simple enough fet for trigger contact protection.  One thing I noticed was the the negative wire was SOLDERED to the fet heat sink fin which is a NO NO.  Just the process of doing so can short out a fet and lead to a short.  When building fets you want to use as least heat as possible (around 25W setting) and very short times when the soldering iron makes contact with the fet.  Excessive heat can kill it.  It's always advised when going this route to simply use small screw and nut to secure to the sink fin. Also a little heat shrink around the resistors couldn't hurt either.
Posted Image


Once the upper receiver was removed I noticed this on the bb feed ramp.  The side tabs that secure it was snapped open and it should have been replaced or at least let the customer know if there was not enough time to do so.  I found the screws to have been extremely over tightened and had trouble getting them out.
Posted ImagePosted Image

SPRING:
The spring is a Madbull M/SP140 (gold in color). Nothing to report here other than that there was a sponge inserted into the spring. I can only speculate that it was placed there to dampen the heavy spring sound when it's decompressed.  Wasn't a good idea however since this sponge broke down and left a very heavy film of sponge fragments mixed in with gear grease all over the inside of the gearbox.  It could hinder performance and lead to catastrophic failure.
Posted ImagePosted Image

SHIMMING/GEARS:   I found visible damage to the teeth of the spur gear.  Only the top side of the teeth edges were warped and damaged which indicates that the bevel gear was shimmed too high and/or spurs gear was shimmed too low.  Maybe both judging by the damage on the bottom side of the spur gear and the gouges on the gearbox shell. When building a setup that runs such a heavy spring in full auto shimming (which I never would recommend) has to be perfect or things like this happens.  
Posted ImagePosted Image

CUTOFF LEVER:  This lever was very worn.  Could be normal wear and tear but it could have also been an overall setup.  I replaced the cutoff in this gun about 6 months ago and the old one didn't look this worn. I read the report by vanevery that stated that this gun shoots in full auto bursts when in semi because of the "excessive heat created by the motor"  or maybe even user error. But judging by the wear on this cutoff, this is the culprit and not the heat or the user.
Posted Image

CYLINDER HEAD:  Performed a standard compression test on the aftermarket type-0 cylinder and the modified KWA cylinder head.  A type of gasket maker compound was used around the cylinder head for better compression when inserted into the cylinder.  The compression test results were poor and found air leaks around the cylinder head.  The cylinder head was removed and found that the compound around the cylinder head had hardened and some fused with this cylinder head.  The surface of the cylinder head is no longer smooth and it will never yield good compression in my opinion.
Posted Image

One last thing to note is that the tiny screw that holds the trigger switch assembly was replaced with a bigger screw cut to length (It was still too long). Found that the hole that holds this screw was stripped out from over torque of the screw.  Even this replacement screw was not sitting securely in the GB shell and had free axial movement. Also the screw being too long with sharp point gouged out the selector plate that sits on the other side of the GB. Not a big deal and happens all the time but just wanted to note my findings.

Finally the gearbox shell was radiused, although I feel unnecessary, done well. Sorry no pics. :)



I am not going to give you a detailed conclusion.  You can do that yourself whether you decide to believe or not.  I am not here to pass judgement but there were definitely things that could have been easily diagnosed, prevented and done better.

I will respond to all of this and Most Specifically Niko's post.

I will make a few points now.
- THAT IS NOT MY WORK Pictured in Niko's Post !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
This gun is now in the hands of a second Tech since it left my hands.
No gun I have ever worked on has ever looked like that.

Motor:
The motor in the Picture Taken by Niko is a ZCI Neo Magnet High Torque with an SHS Pinion Gear that I installed. NOT a ZCI High Speed Motor, which has a different color Can completely.
This ZCI HT Motor has more than enough TPA and Magnetic Strength to pull that spring, and with ease. It can pull any spring!
Funny thing is, that specific motor pictured by Niko is the motor Dru himself purchased and then subsequently destroyed his stock KWA piston with. I did not purchase that specific motor pictured, Dru did.

Main Spring:
- The Spring that I installed is a MadBull m130 Linear Spring.
A MadBull m140 Spring is an Irregular Pitch, Non-linear Spring.
That is a noticeable difference visually that makes each respective spring identifiable, as well as a difference in color coating.
It would be impossible to not get right in identifying these two springs.

Mosfet:
THAT IS NOT THE MOSFET I INSTALLED!
I installed a Zardichar Micro Mosfet.
The one pictured is a completely different brand and type.

Wiring:
- There were no soldering connections nor electrical tape on the motor wires done by me.
That is not my work!
- No electrical work regarding soldering on a Switch Assembly that I have ever done has EVER looked like that.

Shimming:
- The shimming on that gun I worked on was done using a Bevel/Pinion Gear Method.
I spent hours shimming all of Drus guns.
- Shimming KWA gears can be challenging enough.
Double that challenge when shimming them with 5KU 9mm Bushings.
Quadruple that challenge when shimming multi-generational KWA gears.
- Niko mixed and matched Gen1, Gen2, and 3gx Gears in several of Dru's Guns.
This matters because the Bevel Gear Shafts have different specs for each generation as well as other Spec changes regarding the Sector and Spur Gears. This makes shimming multi-generational KWA gear-sets together very challenging.
- The sound of the gun was butter smooth when it left my hands.
What the other techs have done to this gun since it left my hands is on them, and has absolutely nothing to do with me.

Switch Assembly Screw:
That is YOUR SCREW that I removed from the gun and reinstalled when finished.!!!!!!
I did not fabricate some new screw for the gun.
Dude! Really???????????

- I have all of the emails I sent Dru saved.
At no time did I ever make any such ridiculous statements.
Here is specifically what I stated in that report regarding this specific gun and the burst fire issue:

Quote

vanevery Sent: Sat 6/14/14 9:04 PM

- The electrical system was burst firing in Semi-Auto mode.
I informed the customer of this, changed out the Signal wire as well as the Positive wire.
This did not solve the issue and I notified the customer of this.
At this point point business had concluded with the customer, so I did not have the chance to further address the issue and get it resolved.

To niko_gpsy:
- You did not know the difference between:
1. ZCI High Speed motor and a ZCI High Torque Motor.
2. The obvious visual differences between a  MadBull m130 spring and a MadBull m140 spring.
Any professional tech would know these things.
3. You don't know that Gearbox Shells need to be radiused.
4. You called me out for installing your very own Switch Assembly screw.
5. You don't even know the Gear specs of the very gun brand that you represent.
6.. Worst of all, you posted all of these things knowing this gun had been taken to another tech after it left my hands  Niko....that is not my work, man.
- There is nothing accurate or unbiased about your post.

I really wish  had taken pictures of:
- Your R-hop install that could not hit the broadside of a barn at 50 yards.
- Your Shim jobs.
- Your attempt at AOE Correction of a stock KWA Piston.
- Your attempt at added Sorbo
- etc....

To KWA Staff and all Moderators.
To allow Niko's post to be put out there knowing this gun has been through the hands of another tech since it left my hands is gut wrenching.
To not even PM me and say we would like to at least give you a chance to hear your complete side of the story before allowing Niko to post this is noted. I have not even had the time to fully respond to the OP.

Three words:
- Unbelievable.
- Unprofessional
- Undeserving.

Typical, that is 100% unmitigated BS in the highest order. No other tech so much as touched this gun other than you and Niko. Niko had this gun one day after i got it back from you for inspection for the complaints i continue to repeat! Even the reports you gave to me that Niko now has, mirror the the work you did.
