Default First flight succes

Hi, yesterday I maidend my new PC 21. This one is completely wodden construction, and lightweight. Flies wonderful. Knife edge very neutral, and the brakes are very effective. You can aproach with 1/3 power.

I am looking for a distributor for this model in USA, who would be the best one to do this job?

How do these things work, do you control torque and speed, or just torque?

They are free spooling (ala PT-6) with fix pitched props. Jet Cat has an upper RPM prop limiter attached to the gearbox (user adjustable) that trims fuel when the limit is reached, the other manufacturers do not. Static RPM is controlled by the pitch of the prop you select and you can expect up to 2500 RPM to be gained in flight when unloaded. There is no torque control or strain gauges to even check torque values, so I guess it's not a big deal.
