Here is another idea. You could get one of Power Sport's ring gear
and prop shafts. Build a four planet carrier and sun gear to go inside 
the PS ring gear. The HP capability would probably go up to 1000 HP!
Don't forget the rubber torque isolation coupling between E-shaft
and sun gear.

Sorry Ray :-) (Ray don't like no planetaria :-))
