I haven't discovered its top end, but it easily exceeds 650 rounds per minute, and it doesn't sound like it's working very hard at that ROF.

Secondly, you're not going to be able to get a larger motor to fit in the shell without modification. They have already mounted the motor diagonally to get it to fit. And it's a really tight fit.

Thirdly, the reason to go with 180 motors is for torque. The RPMs are about the same as 130 motors. There is no reason to use a high torque motor for the pusher. In fact it would be more effective to use a high speed 130 like an Artifact 4MU that rotates at 50,000 RPM.

And lastly, you're going to run into two problems when you crank the ROF past 1000 rounds per minute. One, the darts will start misfeeding at the end of the stick because the follower spring won't be able to feed them quickly enough. Two, the darts won't clear the cage fast enough unless you seriously upgrade the motors and flywheels.

May I suggest that you build a basic AutoStryfe and just try it at 700 rounds per minute first. It's already insanely fast at that ROF. You can always upgrade from there. For the motors I am actually planning to use Titan Cronus 2. Super high torque.

But the question is will it physically fit a 180 motor for the pusher?
