Paul,
Any idea on the damper used in the single rotor Diamond engine.
I personally consider them a very nice little engine.

I think it is a big rubber donut out of a BMW drive shaft.

Paul Lamar ...No rotor no motor.

The BMW type donut is what I got with the Hirth gear box for the single
rotor. I had it run with direct drive load on the test stand for 5hrs, and
no problem.
