I've had some pretty successful transition flights the past week but am having an issue during the first stage of the transition.
While hovering in QHOVER and switching to FBWA, the FW motor powers up and and I slowly start to increase throttle. If I try to accelerate too fast, the airplane yaws dramatically and does a flat spin / flip maneuver! I'm not sure if this is aerodynamic related because this is a flying wing configuration and unable to keep a good heading at such slow speeds, or if its a Q_RAT_YAW tuning issue... like it is having trouble keeping a heading while moving forward.
If I throttle up very slowly and use yaw and roll commands to keep it straight during the first few seconds, everything is fine after that.
Keep in mind, this is a 3 meter wing span / 15kg aircraft, that's a lot of mass to keep straight!
