I know that George Graham broke "stock transmission redrive" by running on one rotor, but this is the first RWS drive failure from it. Makes me wonder if I should inspect the internals of my redrive, or if I'd spot any telltale signs when I do. Mines an RD-1A and has always had about 3/4 inch of play at the prop tip.

John (wondering why putting wives in airplanes makes everything break).

 

3/4 - 7/8" total lash at prop tip is normal,  but an A drive on that turbo engine?  46" of manifold pressure!    Oh my ache'n head.
