RC Speed boat
« on: September 02, 2008, 02:55:44 PM »
Spent the holiday weekend at my in-laws lake house. Their neighbor had a neat toy... a dual battery cigarette style RC boat. Man, that thing could get up and move. It got me to thinking tho... how cool would it be to build a custom one with a CF body?

So that set the gears in motion for a winter/spring build. I think after I complete the CNC router, I may just have to design a foam plug to be cut on it. use the foam plug to make a mold and from that, a CF boat. i would really use it for anything but to terrorize the fish and turtles in the lake. Now the key question is this... gas or electric? I may not be able to use gas because of the regulations on the lake. But if I were to do electric... how do I make it fast?

Eric

Start by looking at Tower Hobbies web site or check out a few of the forums. Here's one that may give you some ideas on electrc.

http://www.rcairboats.net/phpBB/viewforum.php?f=9&sid=3389af4cf9ba99162e8667c42272f092

It's a direct link to their electric powerd boat threads. May fine some useful info plus links to other hobby catalog sites.

Eric,

For the last forty years, model boats was a passion of mine, from high speed i/c engined monsters to true scale and steam boats.

For one of the best model boat sites, you have to try here.

Thanks for the link John!

This one has been put on the back burner for a few months. At least I have the time now to design it.

Thanks Glen!

I do have a membership at paddleducks. I hope to build a couple of RC ships (along with a plane or 2 and even a zepplin type model)

I have seen some clips of some FAST electric boats.

This clip is a tunnel hull race looking boat.
Its funny cause when he taps the throttles at first.. it sounds like someone is hitting the boat with a large hammer.

Pretty Fast boat..

That first run was done at the same time of day that Donald Campbell did his final run in Bluebird. As a sort of testament to him.
