So i upgraded my M4...

Alright so I find the ROF is a little high, I decide to buy an M140 high torque motor (G&P). As it gets here theres a CQC game in sask so i put the motor in with an MS100 (which turned out to be an MS90, 305fps). So going from 380fps to 305fps I know theres a big difference in ROF so I thought nothing of it. Well due to the cold a post on my sector gear broke and shredded my piston, I just got the new piston in so I install it and a sector gear, stock G&P spring (380fps). Greased everything up, put it back together, loaded a mag and tried full auto.
BRAAAAAAP
Definitely over 1000rpm O_O
Okay so maybe I accidentally put the 305fps spring in!
So I go to chrono, 420 FPS!!
Try firing again, BRAAAAP, yep, still over 1000rpm....
Okay time to put a weaker spring in lol

So my ROF with the stock M120 motor was 800-900, anyone have experience with the M140?
I figure now that it has all that extra torque it's having no trouble fighting the spring and so it's actually firing faster.

You need to find out from G&P the RPM spec's on the two motors and at what Voltage there seeing the readings from!

Any possibilities for a smaller battery?
Last ditch idea, play the game in semi only?

Well the piston didn't strip until I put a 370fps spring in, so I really need to reduce the rate of fire lol
I don't really wanna spend 80$ getting torque up gears so I think I'll just cut the battery down to 7.2v
That's two 7.2v batteries for me now lol
