You guys helped out alot with my prop dilema, but now up to the point of having to put some real cash down on a new prop. I don't want to clip and re-pitch my CM7445 for the C-85 and would rather try to sell it (or keep it) as a pair with the complete A-65 that's coming off the plane as they're both only around 400 SMOH.
In any case, I've been going back and forth between being my cheap self and just getting a Sensenich wood and save a grand+, or just sweat it out and get the Sensenich 7442 metal. However, I have two problems;
I live in the rainy Northwest and while I take great ains to never flyi the Cub in the rain, the hangar still gets very moist inside and I have some concerns given the conditions about the wood prop over time.
Next, in using both the Mac and Sensenich metal prop application guide they list recommend props for the C-85. Dumb question part 2: with the added power of the stroked C-85, will those standard pitch/length recommendation (I guess for the wood too) still meet the static and dynamic RPM limits for the engine? Or, if I were to use the recommended climb prop, can it exceed the limits?
Thanks,
