ive found that re-shimming the motor is one of the first things to do. years ago i built a M4 using a Madbull8mm v2 box.
Was wanting to upgrade the box, piston, cylinder and spring for durability when using lipo's.
I have been into RC racing and have got a bunch of lipos id like to use in the AEG as nimh's are garbage with poor delivery in comparison
