Charley,
   Does Tracy use the direct coupled setup on his RV8 three rotor 20B engine.........?

Joe,  I have kept quiet as I have a conflict of interest, in I sell another redrive that has a completely different cushion drive that does not use the flexplate at all.  It fits tracys reduction drive as well and bolts direct onto the e shaft and has a vulcanised rubber bushing to get the flex.  Sadly it is not cheap which embarrasses me, but such are the machining costs.It is listed on the rotarpower site.  Neil

I  think it will take a while to find all of the emails.

Found pics of Dave’s broken flexplate.

The pics of Dave’s flywheel are very disturbing. 

It appears that the destructive stresses occur between the counterweight bolt circle and the torsional damper bolt circle. 

If a good flexplate could be modified to strengthen the areas could this be a fix?

Clean the flexplate  in the area of the bolt circles and perform a layup of carbon fiber on both sides.

A layer of Eglass would be placed between the carbon and steel flexplate to prevent galvanic reaction.

The mounting plate for the RD-1C would have to be shimmed the thickness of the carbon fiber.

Has anyone thought about this?
