I'm sorry maybe I should've been more clear. The picture was not to
reference the "type" of gear box ,rather that it was a gearbox made out of
carbon. So planetary redrive housing made out of carbon.   Can you refresh my memory as to which gear set to use.

Tony,
Copy the Mistral redrive internals...except the belt driven alternator. It
needs a CS hub (oil fed), a prop gov drive pad, and maybe an accessory
drive. Pics have been posted on here of it.

It also need one of Tracy's torque damper couplings.
