Hello, I am working on my new gun, which is an Echo1 akm (ak74) and am having some worries about the new parts I will be putting in. Here is what I am running: -Mosfet with 11.1 2200mah lipo -Tightbore -CNC hop up/soft bucking -Stock cylinder/cylinder head (compression mods with plumbers tape) -Stock spring (m120 I believe) -Stock anti-reversal latch -New air nozzle with o-ring New parts: -SHS piston head -Super core piston (adjusted AOE with sorbo pad, shaved off necessary teeth on piston) -Lonex tappet plate/trigger contacts -Lonex A2 motor -SHS 13:1 gears First question, the pinion shaft/gear on the new lonex a2 motor is shorter than the stock echo 1 motor, which is leaving me questioning my motor height, as I have the lonex motor at full height and Id like to raise it up a bit more but cant. Anyone run into these issues with a short type motor? Is taking the shaft/pinion gear off the echo 1 motor and putting it on the lonex possible? When running 13:1 gears with the AOE adjusted, do you think I will have to short stroke the piston or shave teeth of the selector gear due to the speed of the setup? When putting in these new parts, is there anything else I should change/be aware of with running a higher speed setup?
