Help! Propeller advice please

[Neil from Leamington]

Hi!
I'm building a Ben Buckle/Keil Kraft Falcon, (like this ^). I will be running an OS FS-60 engine. I want lazy flying. Will you give me your thoughts please on a suitable propeller pitch and size. The plans say 14"-15" to suit engine used.
Many thanks.
Neil

The ideal size is 12X7 running 10,000-11,000 RPM as motors very in power it is a good starting place and check RPM. It will run up to 13X7 if the engine is strong enough to keep RPM`s

I agree with @Bricks
Here is a chart for the suggested prop for OS engines

Thanks for that link. They no longer show the FS60 engine.
