Tracy,
 That is good to know. I have always thought that with the big plain bearing on the prop shaft your redrive would be a natural for CS. I don't think the current housing is large enough to accept any kind of helical drive for the governor though. Please correct me if I'm wrong. Possibly a clamp on v-belt drive at the front? With a lot of people putting together packages for the RV-10 a CS setup is overdue. IMHO

Dave, if you go with a Mistral PSRU you can run any Hyd/CS you want. I'm supprised Tracy hasn't gone to a hollow shaft on his PSRU since he runs a big plain bearing he could set up a port for a CS prop.
