Uh, not that I know anything, but if I
did, I'd say I see your problem. :-) Isn't the stress on a soft
coupling that close to the 'axle' going to be massive? I thought
that the whole reason for putting the soft components out at some
significant radius from center was to reduce the load on them.

All , As usual I forgot to attach a photo, This is the first
one with the green Polyurethane flex that was a failure. New
one has a further lightened Alloy base with a rubber flex.

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..........
