RC hydrofoil

by Fydroy

June 2017: News!!! The rudder assembly has been reworked to allow for a change in the pitch angle. I mounted two servos and mix them (V-tail program on the transmitter). You need two 624ZZ 4mm x 13mm x 5mm ball bearing. I added a new set of back foils (symmetrical) as well. The boat is much more stable now! I think that if you don't want to add the relative complexity of a mixing servos, it should work just by setting up the proper angle and fasten it in place. Thanks for your comments and I hope that you guys will build it, it's a great project! https://www.youtube.com/watch?v=FkvLngxzD9I https://www.youtube.com/watch?v=wZ5s8Pop9LE https://www.youtube.com/watch?v=rXsFfcyyV-E July 26th 2015: This is my latest attempt of a RC hydrofoil. The profile is a Naca 63-412 (both front and back foils). The back foil has a 5deg dihedral for lateral stability. It's in two parts, glued together, in order to print the part without support. The foiler is actually flying but on a very narrow speed range. Enough to make it lift itself and not too fast otherwise the prop is reaching the surface and starts to cavitate. I would really appreciate any suggestion to improve it. As mentioned previously, I’m working on a new hull, in four parts of max 15 cm so it would be printable on a variety of printers. Keep you posted. ------------------------------------------------------------------------- Penny Express – Not 1898 pennies, but just one riding in style! This is my entry to the MakeItFloat challenge. I always wanted to make a RC hydrofoil, so what a great opportunity. This is my first real project with 123D Design and 3d printing and I can tell you that I learned a lot. This boat can theoretically carry 1’898 pennies, but I decided that only one would ride, so I had to find a very special place. After 6 weeks of endless nights and weekends, about 100 hours of total printing time three prototypes and almost 40 iterations, what I expected to be a simple project finally started to lift up
