I have been working on this for a while now and seemed to finally make some progress. I have attempted several transitions now with no real success. The two times I realized that the minimum airspeed was just too low so I was transitioning into a stalled condition. I also increased my control throws, minimum airspeed and cruising speed to help aid in control ability after the transition. Today I attempted this again and all seemed well briefly... this time during the transition I was able to gain some altitude and seemed to have positive control over the aircraft but then shortly after the transition was complete the fixed-wing motor shut off completely... I recovered in QHover and landed safely. One good thing to note is that switching back to QHover or QStabilize really works well when the airplane is falling out of the sky.
Please review the log and video and let me know your thoughts. Thanks!
