Default RE: Prop for a 3.5

Part of the problem is/was the prop. The one that comes with Kyosho and CEN Racing hulls isn't the greatest as it does have a lot of pitch to it and the design isn't so hot either.
You can try the Octura X-437, 438 or 440, M-440 or a Prather 215.
The plane engine isn't a good option as it isn't water-cooled.
Problem #2 could be that you're trying to run it too lean. You need the needle on the rich side to where you here a slight lag when you blip the throttle then adjust from there.
