Tracy, Any chance we might see you at Oshkosh with your new RV8? Robert B
Wish it were so because it sounds like a lot of interesting stuff at Osh this year and the -8 is finally ready for a long flight. But alas, there are too many irons in the fire to leave. Such is the price of goofing off for a month in Colorado. Give us all a report on the best of Osh when you get back.

The heavier flywheel should help
but there is more to it than that.
I was contracted to provide ECUs for
the Itec Maverick, a powered parachute / car.
I recently learned a
lot about idle requirements on engines without a propeller load when I visited
their factory to work out tuning for the engine without a prop load (in ground
mode).
Been working on a new idle control strategy for the EC2/3
that I think will greatly improve the minimum idle speed and smoothness of the
engine at low RPM. Because it wasn't really needed in the past, I
did not have a separate idle strategy in the EC3. I'll report
more when it's all worked out.
BTW, this is the first flying car I've
seen that kicks ass on the ground!

I the the idea of the RX8 plate being thicker may be a
mis-nomer. Someone reported the 13B plate as 0.065, but I measure mine
at 0.08. That is about the same reported thickness as theRX8
plate.
That being said, the renisis plate is shaped better
(more conical), and does not have the nasty lightning holes that exist in
the 13B plate, so it would still clearly be an improvement. If Tracy
changed his damper plate a little, it would be the easiest, lightest, and
generally cheapest fix. Given that the 13B plate has held up for a lot
of hours in a lot of aircraft, it may very well be sufficient.

Kelly,
Its on hold waiting to hear how the flywheel fix works out.
While heavier by a few pounds, I feel that it is the most durable of
any of the solutions discussed to date.
Also, I really liked the idea of Tracy coming up with a way to use
the thicker RX-8 flexplate. Whatever we work out, for insurance
reasons, it ought to be "blessed" by Tracy as the official RWS
upgrade.
