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? Joe L.

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. Dr.1 Driver "There's a Hun in the sun!"
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. Ed

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.
Thanks for the info and also to the others that have replied. Joe L.
