electric hull layout

[anthony_marquart]

Preface,... I'm looking for an electric hull to make a sport .12 hydro with.

I've been looking at some different hulls on the internet and I see many don't have radio boxes. How do they stay dry? That worries me. That means they don't come with a radio box. I can't run without one. ? I'm thinking the hull needs to be about 24-28in. Glass or built up wood hull. What kind of speeds are you guys getting from these hulls, DPI t-plus for example, in electric trim? I'm thinking about 40 with a warm .15 nitro. Am I crazy? I also think I'll need on that has the hatch full length so I can get batteries and things all the way up front.

Does anyone have suggestions?

Electric boats use the whole boat as a radio box. They tape down a hatch or cowling. Motor, speed controls, and batteries don't like water just like radios.

If you want to put in a radio box do it - I run them in my tunnel hulls

Some electric boaters always use radio boxes - ed hughey and doug forrester spring to mind

Hey Guys,

True but Ed and Doug both design that feature into their (wood) boats. Building a radio box into a wood boat is a snap, some 1/8" stringers and 32nd ply and your done.

Not crazy - but I doubt you'd ever get 40+ mph with a .15, particularly a pull-start. The DPI T-Plus is a large boat with a lot of drag, and to accelerate it fast enough to get it free of the water will be a trick. The famous pull-start Miss Bud is lucky to go over 25 mph with its .15. In a rigger or smaller hydro you'll stand a much better chance to get going that fast, but it won't be easy.

If you are talking about a high-output car .12 or .15 then you'll really need a smaller lighter hull. Those motors don't have the low end torque to spin a big prop fast enough to get a big boat going. Remember that electric motors have the most torque at very low rpm so acceleration is ample - nitro is just the opposite. A smaller hydro marketed for 12 cells might be a better choice if performance is your goal.
