Change to brushless flywheel motors

[jeff-winn]

As a consumer faster is always better. The 3S LiPo currently in use is at capacity for how fast the motors can go.

Introducing a single stage brushless setup would continue to improve the FPS at the barrel.

This means:

• A brushless ESC must be introduced
• The motors at the flywheels need to be brushless

The motors may need to be lower RPM and larger to produce more torque to get the inertia overcome.
