Model Forum / Radio Controlled / Water Models / October 2007Hydrofoils
I am thinking of playing with hydrofoils just to see what can be done. I'll probably use an outrunner equivalent to a .40 and a surface drive. I'm not sure how large a hull will be needed. nor do I have a clue as to the size of the foils or their angle of attack. Does anyone have any experience or knowledge of relevant resources? TIA. Hey' From my experience I believe it would much better to get a hull made from fiberglass or better, carbon fiber. a .40 running with 40 to 60 percent nitro with a surface drive will need a tried and true hull that is VERY WELL BUILT! I suggest you look at http://www.aeromarinerc.com/ or some company that has the same good rep for hulls.... I hope this helps, >I am thinking of playing with hydrofoils just to see what can be done. >I'll probably use an outrunner equivalent to a .40 and a surface drive.

You can run an outrunner by all means, depending on how big you want to run the boat will depend on what motor you want to use however. I run a small (18inch)mono hull with a 400 sized high KV outrunner which goes pretty good. If you want to run a hydro, you could start off small to get a feel for it and work your way up. Start with a 1/10th scale hydro that you can easily build from balsa and strengthen the old fashioned way with dope then add a bit of paint and a clear and there is your hull, then you could start shopping around for a larger 600 sized outrunner or something like that from the many plane suppliers around. Even though mine is high KV, I am limited on the size of props to run, lower KV motors will allow you to run bigger props on more cells which equates in a lot of torque. I have seen monos running on 2200KV inrunners that absolutely fly on 10 Cells.
