Paul, I thought that the group felt it was important to isolate the engine
vibration (torque pulses) from the gearbox through some sort of dampening
device? It looks like this is a direct couple to the gbox pinion. Is this the
same design that Everett Hatch originally used? Also, spur gears a very noisy
especially at high rpms. Was this one, or did the exhaust noise muffle it?

Power Sport does not hold that view. They think a real ridgid system
is all you need. BTW Mecanair is using a clutch disk.

I heard no gear noise but the prop and exhaust noise was fairly loud.
