For: Tienly GT-40000 RPM Ultra Torque Performance AEG Motor (Short)Product Information:
ASGI = Fail, again on the description.
The GT40000 is the High Speed Motor. The GT30000 is the Ultra Torque.
If you want a torque motor....do not buy this unit. If you want to spew 30+ bbs per second with standard ratios gears and a 11.1V mosfet wired AEG, get this motor.
Hard Pinion Gear
Not for the budget minded user.
No cons really...check out internet videos and see how they compare to say a SystemA motor.
