Will a G-38 turn a 20-8 Zinger prop? What kind of rpm should I be looking for
if it can? I've been told that the G-38 can turn a 20" prop but now I see it
is outside of the specs (18 ") for the engine. What prop are you using?

I ran a G-38 with a 22-6 on my first 1/4 scale Fokker Dr.1. I was getting
around 6K, if I remember correctly.

Last year when I came upon a used G38 I had the same question. I talked
to a number of folks at a fly-in and the consensus of the guys using
them seemed to be an 18 X 6-10.

18x 6-10 is all I have ever used. I'm sure that you can give and take on the
pitch and dia. I'm thinking mine turns around 7K.
