VTOL of X8 plane
http://diydrones.com/profiles/blogs/deltaquad-vtol-autonomous-maiden-flight https://github.com/sanderux/dqdocs operating manual for vtol plane. http://px4.io/portfolio/quadranger-vtol/ It was outfitted with the PX4 flightstack too which I recently added the VTOL_TAKEOFF and VTOL_LAND support. The maiden flight of the DeltaQuad was a succes. It slightly overshot it's landing site due to a miscalibration of the airspeed sensor (it was flying faster then measured). Still it made for a very smooth flight. In the next few weeks we will start payload and endurance testing, based on the current data it looks like it could carry a 1-2 kg payload for a distance of around 80km. vtol brushlessgimbal

 * http://discuss.ardupilot.org/t/apm-2-7-trex-450-fly-bar-serious-up-down-oscillating-and-crash/9428 Anticipating venture into traditional heli as a main VTOL machine, I learn to set up my old Trex 450 with APM 2.7. I manage to set the rate roll / pitch and yaw and use other parameter as per manual. I manage to get it hover in stabilized mode. When I switch to Alt Hold mode, the model spin up as I activate the switch, I advance the throttle / pitch over 50 %, nothing change or happen, as I continue to advance the throttle, to a point where the heli start to lift off, immediately it goes up and down violently and the main blade pull off from the blade holder within seconds and crash. As I'm completely new in traditional heli, I'm not sure what parameter control this behavior and the manual seems do not offer more info in this area.

Hi Keeyen, I assume the ACCEL_Z_P is still at the multirotor default of 0.500? Try changing it down to 0.100 and go from there. Usually it ends up in the range 0.100-0.200.
