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..........
