Isn't the motor in the Stryker an inrunner? I could be wrong about that. I do know that the motor in the corsair is an outrunner so it may not be a simple swap. Changing the motor direction is no big deal (just swap any 2 of the 3 wires) but mounting it may be another story.

If you want to hop up the Corsair, something like an E-flite 480 outrunner is a fairly easy modification.

I put this motor in mine: http://www.hobbycity.com/hobbycity/s...idProduct=3886 I only had to drill two holes differently in the stock mount and add some 3mm washers to space the motor out slightly. With 20C batteries and an APC 10x7e prop, performance is outstanding. It's much better than the stock Parkzone setup.
