Unrecoverable spin - crash

@bchristal wrote:

First off, thanks for the great software!! Plane 3.6 has been rock solid. However, I have found an issue in 3.6 and 3.7. FLying wings can but put in a "death spiral" fairly easily by stalling a wing. The UAV Mapper flying wing has a gentle tip stall, and will immediately recover in Stabilize or Manual, mode. However, in guided modes FWB, AUTO, or RTL, the spin will not recover. Once started, there is nothing the pilot, or autopilot can do to recover. The plane will spin to the ground. This is not a random event. It will happen every time the airplane is put into a spin.
