Right.. ive got my externals sorted and ive just got the gearbox out and cracked it open. i compression tested the piston/cylinder (finger over air nozzle and push piston) to find no air seal at all (brand new never fired KA m4a1) so its getting a complete makeover. ive got a ascu v2 mosfet on the way and i want mostly shs parts and a 11.1v lipo. heres the list of definates:

shs15 tooth piston
shs alloy piston head
shs air nozzle
shs double o ring cylinder head
shs cnc gearset (what ratio?)
7mm bushings (hopefully terminus x if i can source them) other options?
high torque motor shs high torque is £35 or terminus x is £58

i want a max of 450fps semi only so will be using a madbull m120 and hoping a tbb and perfect airseal will get me close.

need a little help with the gear ratio's and torque motor please

thanks

18/1 (the standard) is a fine ration. The power of the motor and battery will bear the load and turn it with no problem. If you want assurance, know I turn an m170 on the standard gears with a high-torque motor and an 11,1v.

SHS pistons are hit and miss. A batch of SHS pistons were found with non-parallel rails a while ago.

If you can find VS pistons, buy those instead.

If you are willing to pay for TerminusX motors, then I would also suggest Lonex A1, A2 or A3 motors (forgot which one is balanced, high torque and high speed). Its been mentioned the SHS runs really hot.
