RE: FeiBao Velox
As you get more comfy with flying the Velox the trick would be to take it up the classic "3.5 mistakes" high and turn off the gyro and deliberately try for a slow speed stall to see if the CG movement combined with the turbulators has helped or not. If it still goes "cobra" and flips over you've got the 3 mistakes worth of altitude to get back some flying speed and pull out safely with the .5 worth as reserve.
