F19 prop

[Rockket9]

Hello all, I have my F-19 recovered and painted, remounted the engine and my question is I have 2 McCauley props. One is a SCM 6950 and the other is a CM 7443. This airplane has a total of 409 hours on it and the 0-200. When I got it, it was all apart. I’m not sure what prop I should put on. The parts book shows both props for the 0-200. can anyone help?

Re: F19 prop

I have not flown an F19 either way. If I were you, I would fly both props and see which you like better. If you aren't gonna keep it I would like to buy your 7443 for my BC12D with A65.

I had the 74-43 on my O-200 DeLuxe. Climbed like crazy, cruise I did not like. Flew sluggish to me if I pulled the power below 2500 cruise. needed more pitch to me for land use, probably just fine for floats.

I flew the tests with the factory prototype, the 69-50 was taken off my Cessna 150 and used for the tests. Then they bought one; the 74-43 was the "seaplane" prop.
Please try them both record density altitude, temps , distances, Vx , Vy, FT speeds, etc..

I am running a Sen. 7443 and love it behind the O-200, great climb and good cruise on 8.50's. If you want climb, the longer the prop the better, just like the borer props. Tim
