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.

Spur gears are whiny (my new Triumph has all spur gears in it) but they have
another big advantage: Better efficiency! Thus, more power available.
