RE: G62 Prop Choices
I flew my Edge/G-62 combo with a Mejzlik 22 x 10. Worked real well. I really don't like the 8 pitch props on these 28%'s. Just a tad to slow for my tastes.

RE: G62 Prop Choices
You'll do best with a 22-10 prop. Just buy a goos one. Mine likes the Menz Ultra 22-10 on my World Models 80" Patty.
Remember, the Zenoah is an industrial engine. As such, it's ported and timed to run at higher RPM than a DA or ZDZ. You can easily let a Zenoah G-62 run near the 8000RPM range and it'll be happy as a pig in -----well, you know what.
Don't lug it down too much. Try a 23" prop if you want, but I'll bet money that you'll be happiest with a 22-10 on that particular plane.
A 10 pitch isn't really that much. Your not going to be flying it around at full throttle anyway. The only time you'll need full throttle is on a vertical upline. When you pull vertical-- thats when you want the 10 pitch anyway. It'll move lots of air and keep you going up and also in control from the prop blast.
Lots of guys flying bigger stuff than the 28% Edge are using props with 12 pitch. I've seen guys running DA 100 engines on 1/3 scale planes and they have 12 pitch props. Even seen guys running 12 pitch props on 150cc engines and 40% planes.
You have the right idea----big diameter and low pitch, but you don't need to worry about overspeeding the airframe with a 10 pitch prop. Just manage your throttle and fly it around at 1/4 throttle on the flats and don't hammer it unless you got the nose pointed up.

RE: G62 Prop Choices
Not to worry about high rpm with a G62...best power according to Zenoah is at 8500..the chainsaw it's made from easily exceeds 10,000.....
