Sorry to ask that but i'm still a newbie modding my M4
Those are the mods that will be made next week ...
KA casv-m with a 9.6 twin pack in it. ( have a folding stock )
M733 size barrel with short silencer ( cannot go shorter because of the battery )
Want to upgrade the rate of fire but need to stay under 350 fps ... Can i just drop an higher speed turning motor in it ?? Which one would you recommended ?? Don't want too much torque ; have all stock internal and won't upgrade that before next year
Thanks for you advices ....
