IAN, I found a video of what you are speaking of and it explains the dynamic much better than I could even think of. So I learned something.

"lay on their side and beat themselves to death" is a great description of "dynamic rollover" and is guaranteed to happen if some amateur tries to steal a chopper. See: Dynamic Rollover
  Unfortunately, I have no idea how to prevent it in a free flight model, except perhaps for hand launches.

At least yours got off of the ground Smiley, mine just lay down side ways and beat itself to death. Thanks for the video Ray.

Here is a video of my Vintage Aero co-axle rubber powered helicopter, I should have flown it outside because it was totaled in the crash but it was stable until it hit the TV but still I learned much from that short flight.  Shocked
