Brad,
On a standard long-ez, you shouldn’t go any longer than 62”
diameter otherwise you risk a prop strike on rotation or landing (i.e., nose
high attitude). Some push the envelope and use 64”.

I'm Brad,
a student at SUU in Southern Utah. we
are constructing a Long EZ air craft. We have the 13b with turbo and
Crooks redrive RD-1C. We want to put a two blade prop on and we are
trying to find out what length can be used. What is our limitation and
what has worked best for people. If any one knows what has been used and
has worked please help us out. Does 68" sound reasonable for a two
blade prop? Any info would be great. Thanks. Brad
