Tokyo Marui Evolt AEG System

I think you would a little MR30 to MR30 extension cable to be able to extend the gearbox wiring into the PTS stock but they are easily knocked up.

no you are correct but the combination of new mosfet and recoil weight is hopefully going to be a better shooting experience that just the sewing machine noise you will get with the non recoil version.
 
I've mentioned this before but possibly worth mentioning again in here; on my NGRS MP5 I had the connector swapped for a normal deans and it works with bog standard 7.4s. Haven't used it extensively, but it absolutely shoots, cycles nicely, nothing weird. Obviously this is not widely tested so this is not legal advice and I'm not your lawyer (on account of not being a lawyer).
 
My NGRS MP5 actually came with a MR30 > Deans adapter, and I've run it that way since (probably 4-5 full game days) with no problems on VapexTech LIPOs.
 
The proof will be in the pudding, so to speak, but I guess it depends on the logic of the FCU and what it defines as a safety condition. Possibilities include -
  • No checking at all, any battery will work.
  • Overall voltage checking with upper/lower limits - maybe any 7.4v lipo works, but 11.1v don't.
  • Individual cell checking - gun won't work at all without being able to read each cell, requiring MR30 "balance" wired battery.
The MP5 they clearly expect you to be able to use other batteries because they include a tamiya convertor, which doesn't look to be the case here. Maybe the board *is* exactly the same and there's just no connector adapter because of space issues. Then again...
 
I see. The battery fitting does seem a faf. Wasn't a fan of the recoil and I don't think I like the look of this either. Also noticed the lack of trades. Being stuck to use a particular stock because of the recoil system isn't great. I'm a fair weather player now (if at all) and the mws fits the bill perfectly without all this over complicated mechanics and electronics. I also like my 20rnd mags which I imagine will never be an option as will the original recoil. They've kinda made what the original recoil should have been and added some different drawbacks.
 
I have a sneaking suspicion that the middle wire on the Evolt will be for the largely unspoken about Internal resistance of a Lipo battery. My guess is the MP5 has it but doesn't lock the AEG if it isn't there but on the Evolt it will be a "safety feature" and stop the gun from working if it isn't detected.

For info the IR is the Ohmage value of the cells and usually higher C Lipo's have a lower (better value) which might explain why the MP5 battery is 35C (most AEG's run on 20/25C Lipo's). The IR value is what kills a Lipo's eventually as over time it will increase generating more heat which puffs up the Lipo and it gets to a point that the resistance is so high that amps can't flow.

In theory, if you know what the Ohmage is meant to be then you could loop a small resister into the spare pin on the AEG plug and fool the Evolt into thinking the IR detection was present.

It's for a temperature sensor inside the Marui Li-Pos.

sort of. The IR Ohm reading can be converter to a temperature. If the Lipo is doing the temperature checking then it might be a straight digital 1 or 0 to tell the ECU that everything is good or bad. That makes a bit of sense as the 1 or 0 will go to a pin in an IC that keeps the AEG working when it has the right condition. I might tap my MP5 battery to see what is on the 3rd wire. I'm guessing 1.8v, 3v or 5v or something along those lines.
If I can find a decent hi-res photo of the new ECU it might be possible to identify an IC that takes a high-low input to function.
