I have a Byron P-47 with a Precision Eagle engine, Purr-Power, and a 4-blade prop. I have had this plane built, maintained, and ready to fly for 12 years (seems like I always put it off another year). Have you or anyone ever flown the P-47 with this set-up? Have you flown your Hellcat with the 3-blade set up yet? I take it from the latest threads that you are now using a 2-blade system with a completely different muffler system too. I've never started the engine because I don't want it sitting extensively with fuel in the carb if I'm not going to fly it that year.

I also have a Byron P-40, Hellcat, and Corsair (kits) that I will be building (I plan on building one a year, starting with the Corsair in September) and using the Sachs/Precision Eagle 3-blade set up. Would you suggest that I build them using the 2-blade system instead, right from the beginnning? I so love the look of that big prop on the front!

Right now I am trying to work the kinks out of my Byron P-51 with the Prop Reduction drive on it. I have been running the system extensively on a test stand until I can get serveral reliable runs at 100% power settings (no component failures) before putting it in my plane . Do you are anyone have any experience with this set-up? I bought the Prop Reduction used and completely rebuilt the unit but I have had a couple of bearing failures. I think I've got that ironed out now and will be installing the system in my P-51. I'm getting 3,000 rmp out of the 4-blade prop at 100% power using the reduction system and a Q-35. I believe that is about normal with the Q-35. Any feedback?
