I finally got a prototype autopilot board up and running with a gyro and a small but powerful Arm Cortex-M3 microprocessor, so I decided to throw together a tiltrotor. I am still trying to figure out pitch, but there will be videos to follow.
The tilt mechanism is from cheap front wheel 4mm landing gear stuff. The motors are HXT750s from Hobbyking and I am using HK SS 25A ESCs. A video to follow! (Hopefully with some successful flights!)
