40cc prop sizes...

I realize that engine and application have a lot to do with it but I am looking for the general range?

18? 20? 2-blade, 3-blade?

Nik, a 20*10 two blade is the way to go for general application. If you want more thrust and less speed, then go with a 22*8 prop two blade.

A ZENOAH G-38 SWINGS AN 18X10 TWO BLADE, 17" THREE BLADE. A FOX 2.4 SWNGS A 20X8 TWO BLADE AND A 19" THREE BLADE. THE PROP SIZE ALL DEPENDS ON WHAT ENGINE AND WHAT YOU WANT TO PUT IT IN. (WHAT AIRCRAFT)

Nik, I run a 20x8 on my 41cc for everyday sport scale flying.
