MX7-180 propeller

Post by Hobohiker »

I have a question about alternative propellers used on the fix pitch MX7-180A. I know several of y’all out there have the McCauley 1A200 82/4x propeller on either by 337 or other methods, whether approved or not. Has anyone tried the Pawnee prop, 1P235 84/xx prop? It’s lighter and skinnier than the 1A200, weighing only 2# more than the stock Sensenich prop whereas the 1A200 is 10# more. Cub drivers seem to like them. I’d imagine 31” bush wheels are a must with a prop that long and maybe even extended gear.

Alternatively, how about the Sensenich carbon fiber ground adjustable prop? I think on that prop I’d be more concerned about the significant weight reduction on the nose, being kinda tail heavy already, but I’d like some input from someone that may have “experimented” with that prop already.
