reducing electrical resistance in the system will increase rof and trigger response ie: nicer wiring, remove fuse...

Snappier trigger response comes from lower electric system resistance or mechanical speed.

A higher torque motor and lower ratio gearset will give you faster trigger response time, but rof will increase as a result. A high torque neodynium magnet motor (JG blue or SHS or lonex) paired with 16:1 ratio gears will give you a really snappy trigger time, but with an 11.1v 20C lipo will give about 30rps. This is when shimming and AOE adjustment is super important... pistons will strip very easily at higher speeds. Factory gearsets are around 18:1 (turns of motor to 1 cycle of the piston)

You can have ridiculous trigger response but your gun will probably fire >20 rps... that's when you start adding in stuff like computerized mosfets to drop ROF but maintain trigger response.

A bigger battery provides more current and will achieve what you're looking for, but at the expense of burning/scoring your trigger contacts from increase current arcing.

It all depends on how you want to get to your goal.


My p90 does about 30rps when I let it loose and my g36 is doing about 32-35rps. I have triggermasters in both to give me 100% motor speed on the first cylce and it automatically drops the voltage on the motor to whatever I set it at... in my case 50% so I get 15~ rps rof without wasting ammo. 30 is a bit excessive, and my midcaps run dry in a 4-5 second burst at that speed. I could technically achieve 40rps on my g36 since it has an even faster gearset, but I have to do extensive modification to the piston assembly to make it lighter.
