My Fighterbird has taken to a new problem. Past two flights, it starts off OK flies just fine for 5 - 7 minutes and then goes into a Death Spiral(tm) dive heading nose-to-the-ground and spinning (right one time and left the other). The last time I was able to recover from the Death Spiral(tm) with hard right rudder and no power, but only long enough to fly straight into a nearby tall solid object. I did not have the opportunity to see if flight would stabilize as I managed to break the wing on impact.
Any ideas? Anyone else see this kind of behavior from a Fighterbird or other similar plane?
