RE: modifying props ???
yea, I bought a 3W 20-10 for my MVVS 35, hoping I wouldn't loose to much RPM over the unefficient Zinger 20-8 Pro, (Zinger really should rethink their name "Pro" for that hunk of wood), I got 7500 RPM with the Zinger, but once I get my carb back I think the 3W 20-10 will lower my RPM's more than I would like, so I will shorten it if needed,,,
I have seen guys shave the last 4,5,6 inches of their trailing edge for pulling power, my plane is a GeeBee Y and I want speed so I will be wanting to shorten my prop,,, can't wait to get my carb back !!
