    I am very surprised as I have put 1000 hrs on my coot pusher with a
 Warp drive and have had no problems with it.

I think it has to do with the torque reversal of the four cylinder
Lyc's Ken. They are death on all kinds of props. The rotary is much
easier on props as the torque never goes negative in the
two rotor or above.
