Very powerful motor. I have this for my custom m4. I like the half shaft for pinion gear replacement :D This motor has pulled back a 120 spring at 21 balls/second for 40000 rounds (most of the time semi auto restriction with a mosfet which started and stopped my motor in less than a millionth of a second.) It is still going strong and I recommend it to anyone. It's quiet too. Adjust properly or you will have a messed up pinion gear. A bit on the long side compared to my jg motor. This thing whipped out my tax forms, but made me fill them out and pay them.
Very powerful motor
Half shaft pinion gear for easy replacement
9.6 3800 mah lasts all day
A bit long so you will have to adjust the height out like 1/8 of an inch (from a stock jg motor)
Doesn't pay my taxes
