Recomended Prop Sizes for OS160FX
Is there a chart somewhere that show recommended prop size by specific engine make and model?
More specifically, the recommended prop size for an OS160FX - I purchased the engine to go on a used Hanger 9 Ultra Stick 120. This plane is set up with tricycle gear and thus the recomended prop (as per Tower Hobbies) was a 17x13. Unfortunately, this prop leaves very little ground clearence.
Since I just fly around a drill holes in the sky (with a loop and a roll once in awhile), I was thinking of going with a 3 blade prop that might provide me with better clearence. Anyone have suggestions as to what to go with?

The "Rule of Thumb" for 3 blade props is to drop EITHER 1" in pitch OR 1" in diameter.
Have you considered using larger wheels to get more ground clearance ? Wheels are probably going to be cheaper than a 3 blade prop.
