Sounds like a short circuit to me. Shouldn't be a big problem at all if you can reattach your wires correctly and cover up or replace and exposed wire.

Honestly. I'm not surprised.

A freind and I used M4 Sportslines from Classic army, and they were the embodiment of pure shit. The piston guide rails ended up somehow bending out of place on my freinds gearbox, and my own gearbox couldn't seat bearings properly.

Either way, they were a failure in the waiting.

Think of the motor gnomes!

Motor smoking is bad for your health..

If you must smoke motor, try not to inhale

I had a classic army motor go in my metal m4 a couple years ago did the same thing as yours an about the same time frame and amount of bbs through it replaced it with a tm and never had another problem with it

I bought ARMY l85 and the smoke comming out and it is very hot at the stock. The gun is new, I have not fired a single bb from it, I have ordered it from wgc. Is it a motor problem or what?

Could also be bad wiring. (to Mboricgs)

What should I do? It is brand new gun.

I would start with disconnecting the battery

then I would contact the seller for an exchange

Also connectors. I had Tamiya or Mini type fail on one of my guns. You should switch them, problem gun or not switch to deans, XT60 or other connector.

I have been using Tamiya connectors since the very 1st TM I have yet to see a switch burned, the only time I see it burned was when it was improperly assembled, shitty wiring or too much current going through. I use tamiya connectors on all my guns now with LiPo

To the OP you have a short for sure, I've seen guys with those vented motor plate shorted out their motor because of moisture getting in

I have fixed the problem with smoke, the wire were touching gearbox. But now, the gun is working, then stops. And I open it again, it work, and stops, again and again..

Crap wire, loose connection..

How to fix that?

new wires, tight connections

Thx a lot, guys.

Is there any tutorial how to do that?
