I've been looking for a small brushless speed control that has reverse - to no avail. What I'm going to try is a brushed gws motor with a small rc car speed control - at least give some idea of potential. I doubt that a controlled inverted hover will be possible but the braking effect of reverse thrust will be neat to mess with. If anyone knows of a small brushless speed control with reverse please let me know! I'd like to eventually design a plane that can fly both ways.
