Not so. The problems were with blade-flap when using the Warp Drive prop.
Other props didn`t "vibrate".
The effect was similar to torsional vibration, however, and took alot of
development work to get rid of. The other BMW conversion that is currently
on the market in Europe can`t be used with the Warp Drive prop
