Kelly and all,  The flexdrive I now have under test for the new redrive bolts directly onto the E shaft and is not connected in any way to the flex plate, other than to hold it onto the E shaft.  I originally used polyurethane as the "Flex" but it disintegrated within hours.

Next was to go back to a flex rubber vulcanized coupling that looks great but yet untested.  The rubber is the same as engine mount rubber and if that fails there are many grades of rubber available.   Results shortly once I get my new Fuel Tech ECU to actually run the engine!!  Neil Unger.

Mark,

   The RD2C  direct  "Rigid" connection from flywheel to the Redrive is somewhat a mystery to me and I suspect to most on the "Flyrotary" list.........I have never seen any photos of this setup and only vague descriptions.........I  do not know if any on 

the list purchased A RD2C and am aware of only the one installed on Tracy's RV8.........

  

   If any on the list has more knowledge or actually has seen one please speak up and provide photos if possible.........I personally have gone with the a (13 lb) steel flywheel and the"Soft" damper provided with the RD1C by Tracy......This is the "Fix" for a failed Gen 2 flex-plate used by Dave Leonard on his Turbo/13B RV6 while racing at Reno..........

So with my inability to find a gen2 RX-7 flexplate I have ordered a lightweight steel Flywheel from RacingBeat.

My thoughts are to have the 4 bolt holes machined in the flexplate or 6 holes in the spline and drill out the rivets to remove the damper plate.

From reading the archives it seems the spline directly mounted is what Tracy did for the RD-2C but that it's a different spline setup.

Anyone done this? Am I better to continue searching for the auto flexplate?
