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..........
