Solved Best prop to maiden this plane?


Well-known member
I have a prototype FB plane I'm building based on an old balsa design and was wondering based on the specs, what prop out of three choices would be best?
This plane has a 20" wing span, and will run on 3s with a FT Radial 2205(big motor because it needs very forward CG)


My prop options are 5x3x2, 5x4.5x2, 6x3x2

I do have three bladed props, but don't really think those would be suitable. I've got 5x5.3x5, and 5x5.5x3 Hulkies which are noticeably more powerful.

I know all these props would work, and none of them would fail...but which one would be the best choice for this particular build and why?
