Hey all

so recently I picked up a Systema Turbo Motor for my echo 1 AK700. The gearbox has been sorbod, corrected for AOE, perfectly shimmed, and a DIY mosfet installed. Gun was running great with the stock motor but trigger response and ROF was only so so.

To make a long story short it ran good with the new motor but the mosfet would get extremely hot when using the gun on semi (after only a few shots). On full auto you could do sustained fire and it would be fine. Although the mosfet would get hot the battery and motor stayed cool. shortly after this the gears disintegrated in the gearbox. So I am searching for new gears that will possibly solve the problem with the heating. I don't think it had over a m120 spring but I could be wrong.

My question is what ratio gears should I go with?

Thanks!
