<div id="post_message_23453295">New to Four Stroke engines, I'm putting a SAITO .91 AAC in a Great Planes RV4 .60 ARF. What would be a good prop for this plane and someone who's just starting into Four Strokes? I'm guessing a prop in the middle of the manufacturers suggested props? Thanks.</div>

I do a lot of prop testing with all my new planes but with the .91 I usually end up with a 14X6 or 8. Depends on the plane as much as the engine but 14 is where I start my testing.

I've also used a 13X6 3 bladed prop and really liked it. It has a braking effect on landing that I like and I liked the way it flew. You need to test a few props to see what you and the plane like . ENJOY !!! RED
