Paul,
George Graham posted a note on the Plugs Up list that he had a
failure on his gearbox.  I wish that I had kept the post but I
expected him to forward it here as well.  Anyway, IIRC he stated
that the engine was running rough, maybe only on 1 rotor, during
a ground test.  He shut it down and while looking things over
found that the prop would turn free of the engine.  He tore the
gearbox down and found that all the 2nd gear teeth were stripped
from the shaft.  If I made any mistakes here George, please
correct me.

Someone on that list also gave a possible solution:  intall a flywheel.
I don't know if he has a flywheel already or not, no response from
George yet.

>From George's message, I got the impression he doesn't have a starter,
sounded like he was hand propping it.  Is this true?
