I did run with a prather mount and it didn't help ,so I put the tilt mount back on. The steering servo is a Hi-tec hs-645mg with a wheel. the steering rate is really low (around 25%) Side to side throw at the prop is about 1" either direction.

What height and angle is a good start point? I have the height set so that when the hull is flat on the bench, the center of the prop is level with the top of the bench. the transom has a set angle, how do I change that? I put the stock mount back on because the adjustable one I used made no...

I got this hull from my boss at work and had to put a bunch on $$$ into it to get it water ready. I've never had a tunnel hull and thought it would be fun. It has a K&B 3.5 in good running order with the self tilting mount. The steering cables are tight and there is virtually no slop of the...

It seems that this project will die. The plastic is way too brittle throughout the boat to support an engine. I started to smooth out the bottom to get rid of the warp, but I ended up cutting a section out........... Normally the plastic won't break when bent, but it is so old it breaks like...

I'll do that, thanks.

About 18 years ago I built an RC boat from plans I found in a 1968 popular mechanics encyclopedia. The hull is made from ABS plastic and is 49" long and weighs 9 Lbs without running gear. Some people have told me it looks like a Crackerbox boat. My grandfather helped me build it before he...

Wow...a LOT of good reading. None of which I really understand. I came here looking for the shapes of sponsons and which one might be the best for a "different" application. You see, I run air-propped boats, Flat bottom and more recently 3-pt hydro, air propped boats. I like the large scale...

Just thought I'd show off my new air propped hydro. It's 42" long powered by a stock Zenoah G-26 airplane engine. Let me know what ya' think. And a video.
