AttoPilot - TriCopter and G-force AutoLaunch Testing

VTOL Tri-Copter being flown with IMU AttoPilot, using CCPM mixing. This is assisted mode, where AttoPilot provides rate dampening (roll + pitch + yaw) through the CCPM mixing, as well as IMU-referenced attitude control. Attitude and yaw is controlled via joystick.

Disclaimer: This is after literally only 4 hours code work on tri-copter and was fighting issues with thin GWS propellers deforming under load. I believe the initial results are excellent, but much much better to come.

My initial "auto launch" was a G based setup but I just don't think it is safe. Even if you include speed over ground and airspeed as sanity checks for being airborne, if it doesn't kick in then the plane is toast. If you drop the plane or what ever the prop can go live depending upon failsafes ect. I just would never want to have the pilot/operator out of the loop for motor control on the ground. Kinda like setting your keys in the trunk of your car....not a good practice. I believe in Murphy's Law!
