I tend to be conservative when shooting the gun so I don't get too much heat.  I let my brother in law have at it and he emptied half a mag in full auto, then switched to semi and back to full auto.  He handed me the gun and the pistol grip was really warm.  

I am sure this is normal, but I have read several posts in other forums of the motor getting hot.  Is this common for anyone else?  Has anyone done anything to get more air to the motor?  I know the base plate acts as a heat sink, but I am wondering if there is something else that needs to be done.

I haven't gone crazy with the full auto yet, but I haven't noticed any heat at all. Are you sure his hands weren't sweating from the crazy power of the KM4 ;)?

When you say "emptied half a mag" you mean 500 hicap so 250 rounds, was it continous, if it was, just to inform you, that is VERY unhealthy for ANY aeg, KWA or not, it will wear the gears and create massive heat and firction and possibly strip your gears.

So your saying the heat is normal.  I understand that sustained full auto fire is not good for the gun.  I just wondered about the heat because others have commented on warm pistol grips.

All motors generate heat and it is normal to have the heat transfer to it's surrounding areas, in this case the pistol grip/heat sink.  How much heat is generated depends on the duration of continuous operation.  The basic rule is "Warm is ok, but not hot to the touch".

Sooner or later a part breaks so you get it fixed or replace it. New stuff show up and claim to stand more abuse.
Just have fun man! Youre not spending that much money on a hobby just to feel bad about it after it breaks right? Have fun  :D

I am with you 100%.  In fact, much of the allure of Airsoft, to me, is working on my guns.  I love tinkering with them, fixing them, troubleshooting them, etc.  I am not so worried about breaking stuff because I like having the excuse of breaking it all open to find and fix the part.  I guess I am a chronic modifier.  I tend to customize everything I own in one form or another.  

Also, I like to keep my guns running at their peak, so the heat question was more of an efficiency question.  Wondering if there is something more that can be done to get more air to the motor and keep it cooler.  Like an additional heat sink or something.  

Thanks for all the responses.

I fitted mine with a Magpul MIAD grip. The motor cover plate on this grip is vented.

By the way this is STORM of TFR. See you soon on the field.  :)

Arnt these are Magpul Replicas? Magpul is a real steel part manufacturer. Its funny how the Airsoft replicas could cost more than the real deal.  

ouch I just read from an airsoft site that they do make replicas (dunno how true this is).  :lol:  They said magpul is making a traning weapon...

If Im correct, in most Countries theres things called Trademarks, which means the name of your company can only be used by YOU (if you franchise is Trademarked), if it says Magpul, I would put my money on it that it was made by Magpul. Heres a paragraph on the describtions for one of the products

"Magpul has made an excellent reputation for themselves with their wide range of accessories and parts for real steel firearms. They are one of the first manufacturers that has embraced Airsoft as an expectable form of training and simulation for real world simulation. Recently they have embarked on their own line of Airsoft accessories, such as stocks, magazines, etc.

Now they have released their own Airsoft version of the popular MIAD (MIssion ADaptable) Grip. This grip features improved ergonomics and positive rough texture on both sides and the rear backstrap. It also features real MagPul trademarks and logo. With a variety of colors the MIAD grip is an excellent choice for anyone looking for a new addition to their M4 or M16."

Click HERE to look at that product. <_<

Yes Magpul does hold the same license to their products in airsoft replica.  MS Infinity is their airsoft branch and it's located in Hong Kong.  They are the one that file law suit against CA making a M93 stock without permission and won.  I visited their office in HK in Feb and I saw all the CA brand stock and also the mold.

Thats really great news! I have seen alot of magpul copies and was puzzled when someone mentioned about magpul grips hehe. I know most of you already know that if you live in asia youd have to be very anal to tell the diff from the real deal and the copy. I honestly was thinking that those were only replicas. But if MAGPUL is the one making it now I think it draws a thin line from Airsoft Replica and the real deal.   Heres my real steel Magpul CRT and Maids...Posted Image Im gonna get the airsoft version (PTS??) !!! heheh


Magpul m93 on my SIR Military version eheheh
