Has anyone thought about a Pitts S1 with a TP-100 turboprop?

There would be some CG work to do and more fuel volume to chase but if the power and weight claims are close it'd be a fun 30 minutes. With a single-stage compressor it is a thirsty little engine.

  • Dry weight of the engine is 136lb. Figure ~200lb by the time you have oil, accessories and a prop.
  • SFC is .863 lb/HP/hr (214 hp) at max continuous so fuel flow is about 185 lb per hour (27.6 gph).
  • Takeoff power (5 min) is 241 hp at a slightly better SFC of .847 at 204 lb/hr (30.5 GPH)

I'm not too serious, I'm just curious if anyone else has already thought about it.

I know about the Turbo Raven and Toucan with the PT-6's but they're in another piggy bank category. This one is only moderately too expensive :D but is comparable to a new AEIO-540.
