OK.. so I've made the recommended upgrades

1. Madbull M120 Spring
2. Lonex Burgundy Super Hard Piston with 10 Steel Teeth (swiss cheesed)
3. I even removed the bearing assembly from the piston head to lighten the piston even more (have a bearing spring guide)

Now i have another problem though. The 9.6V 1100Mah Stick battery i have in the gun no longer appears to have the guts to fire the gun. I press the trigger.. i hear the motor click a little but nothing happens. When i throw in my 11.1V Lipo it shoots normally.

I was originally running a G&P M120 motor but thought that might be too fast with the high speed gears and that's what was causing the pre-engagement so i put the stock Classic Army High Torque motor back in. (this seems like a pretty weak motor though... i can easily turn the pinion head with my fingers with little to no resistance)

I have a few suspicions:

1. The battery in combination with the stock motor just does not have enough guts to pull the upgraded M120 spring and piston (this lonex piston is quite heavy even after the lightening i did. The piston body itself without the piston head is ~17-20G)

2. The battery is just starting to crap out (the gun and battery are less than 6 months old though so it shouldn't be this)

3. The stock motor does not have enough torque to fire the gun running a 9.6V (which would explain why the LiPo can seem to turn it over enough to shoot the gun but can't be good on the motor)

So im back to more issues with this CA MP5K..

1. Should i buy a better quality high torque motor (something like the SHS High Torque?) I'm done spending a pile of cash on this thing.. so not getting an $80 motor..

2. Should i look for a better quality stick battery? (options are limited with the available space in the mp5k model)

3. both 1 & 2?

arghhH!!!!!
