FP motors are better, because you can achieve a higher speed (roughly 19,000rpm) if i am not mistaken. And if you were to create a fly wheel launcher you could overcome the lack of torque a FP provides. Also once you are up to speed you only require minimal current to sustain the launcher. But dont go quoting me i could be wrong. Feedback?

Also the only problem I can see is connection between motor and wheel, direct drive would be best.
