Default RE: K&B .65 Sportster (yup, more from me)

ORIGINAL: hooty301

Its bigger than it looks, 32'' long x 18'' wide. The first couple times I ran it, it seemed like the .65 was too small for it given its weight. Since I've been switching props and the speed is getting better, I'm getting to be a bit happier with it. This same boat design and construction with a 91FX ran 38mph+.
Hello there, looks like your have fun with your boat.
The 38mph was with a .61fx apc12/4. The 91 was added later just too see how high she would fly
I stand corrected. I know the .61FX spins about 4k faster than my K&B so I doubt I will see your speed, especially since my boat is over a pound heavier and my rudder isn't super efficient. I have gotten 30.3 from it on a 13x5 spinning at 10,500 - Just waiting for the engine to get its bug out and run right. I have an APC 13x6 to run on it when its running again. I'd be ecstatic if I could see 35mph. I haven't had the nerve to make a engine mount to run both .65's I have but I think that might be too top heavy to be stable..
