Hey everybody,

I just recieved an m203 and I plan to rewire back to my crane stock as soon as I can.

If you all don't remember, I rewired my gun twice, to the back, and when my battery fired, and then back to the front. This time, I am going to wire it right. ;)

My wire has lots of solder marks on it, and I don't plan to just cover it with heat shrink. :lol:

I want to replace the wiring entirely. The trigger contacts are fine, I don't mind if I have to replace them, but the wires have to go.

I was looking into the ICS wiring (I heard it was good, the link is right here) and I thought that I may get better trigger response if I got some of the Promethieus low- resistance wiring (Here). Is there that much of a difference between this and the standard wires I can get at my local Radio Shack?

Also, I was wondering how hard it was to take off the trigger contacts. I haven't done it in the many times I have taken apart my m4.

Thanks for your help! :)

You woudnt notice the difference. Systema also has a wire set that I have tried. Which contact? the wire sets come with the contacts so you just have to replace them. Thyre just screwed in.

Ok thanks.

So the Prom. wiring over the standard wiring doesn't give me that +1 bps?

I really cant say.  But its gold plated so it should be better.

Prom wiring is gold plated? Huh... That must mean it is better, because gold gives a good flow of electricity. Can anyone confirm this?

So would you reccommend me using the ICS wiring set or buying the Prom wiring and doing it myself? Would there be much of a difference between those 2 wires?

The wiring isnt. The connectors are.

Installing should be the same with both since theyre both wire/switch sets.

Alright, thanks for your help! I will just go with some gold- plated connectors my local hobby shop has. :)

If you want the best contact to contact silver has a lower on contact resistance to gold. However gold does not oxidize and has a lower internal resistance, silver also needs to be coated or treated to avoid oxidation, its also cheaper. In our particular application the total resistance change between materials of the wire is not going to make much of any difference as long as you are comparing wires of the same gauge. I would just go with the wire that suits your needs(such as fitment) and budget the most. For connectors if your talking about the battery to gun connectors I'd just go with Dean's plugs, they the most widely used higher current plug in the R/C industry, not terribly expensive and quite well made. They are rated for approx. 35amps, where the white tamyia connectors are somewhere around 15~20 amps if I'm not mistaken. If you need higher current plugs yet, get Brushless Motor R/C bullet connectors, they are rated for 150amps! and are more simple even then Deans plugs, but they are a pain to solder and they have no reverse current protection.

Cool, thanks for your help.

I like your opinion on what wires I should get. Budget doesn't matter too much, as long as it is not a crazy high price for a few inches of wire.

As for connectors, I was mostly referring to the connectors to the motor, sorry I didn't clarify. I have to keep my tamya connectors, just because my buddies and I all have to use the same type of connector in case we need to swap batteries. Also, I solder my Tamya connectors on, I think this may help a little.

One last question, if the wire is stranded, will this give me a better flow of electricity compared to wire that is not stranded?

Answer: No, it will do the opposite and give you higher resistance and a lower maximum current. The reason is quite simple, think of electricity as water, you want to move it from one area to another through pipes, which will have more flow given you have the same out diameter of the collection of small pipes bundled togather as you have with one big one? Simple the large pipe will be more efficent because there is no wasted space as there is in between the smaller pipes bundled togather. The purpose for multi strand wire is flexibility and wire life when its constantly being reshaped because the small strands are more easily bent and they are also aloud to actually shift inside the wire tubing. Higher stands = better efficiency compared to lower strands because there is more cross sectional area for the current to flow through. So a good quality flexible wire will be of high strand count regardless of materials. Silver high strand tends to be the most durable and cost effective. Its also most commonly used in High Current applications in R/C and much easier to solder than copper because copper absorbs all the heat from your soldering iron ;-). Hope this helps.

As for the connectors on the motor, if your rewiring I would suggest trying gold plated terminals, I think they are only a few dollars. You could also solder the wires directly on if you leave and extra inch or so of wire, to take out the motor you would need to pull it out of the hand guard partially, unsolder the wires then fully remove the motor, I've done this before with a TM M733 that had damaged connectors, its not bad unless your constantly pulling apart your gearbox, and in a KWA i don't see why you would.

Lastly for the connectors going from your gearbox, battery and charger, you could use dean's on your stuff and just make an adapter since your soldering savy, then you would have the most efficient system possible and still be able to use your buddy's stuff and vica versa. Depends on how much room you have,but i don't think and adapter would take up much extra room.

You make very good points. Thank you for taking time to post a detailed message :)

I think I should go with deans and just get a wire adaptor. This would be benificial to me and still let my friends use my batteries.

As for the connectors to the motor, I know I would get a higher flow of electricity if I soldered it on, but soldering it would, as you mentioned, make it harder to take the motor off of my gun. I like to have a gun that is easy to disassemble, so if I have to take it apart to fix something, I would only have to worry about the problem I am having, not the problem and un soldering the solder on my motor.

Thanks for your help :)

One last question, the ICS wiring says it is for a retractable stock, so it would work for my crane stock, right? I was thinking it may mean for an extrenal battery holder. Also, it says for ICS m4, so would it work with the KWA or is there a difference? Sorry I am over- analizing this  :lol:
