Default hydrofoil plans

I tried the search for any posts about hydrofoil plans to no avail. Therefore, I come to the experts and ask if anyone has or knows where to obtain plans for constructing a hydrofoil. I prefer power to sail, but at this point either will be okay.

Default RE: hydrofoil plans

try http://www.foils.org/gallery/model.htm for a interesting but complicated hydrofoil. Go back the main site for more information. I have built a hydrofoil from Model Boat plan (www.modelboats.co.uk )MM 1021 Lecrofoil, worked but used a lot of power so short running times. There were 3 powered and 1 sail hydrofoils in the old plan book but do not know if these are still available, though Xlistplans may have them. I also had a Nikko hydrofoil converted to R/C which was very good and there is a Japanese kit of a hydrofoil ferry to be constructed next when I finish the present model.
http://www.home-taylor.freeserve.co.uk is worth a visit, mainly wigs but also hydrofoils.
Come back to [email protected] if I can help

You could contact Umi, I recently mailed a copy of the Sparviero Hydrofoil, maybe she'll make a copy for you and put it in the mail.

Regards, Jan.

Yes I have the Sparveiro plans, and they can also be modified(in length and supersturcture) to build up the Tucumcari PGH-1 that Boeing Industries produced.

I have yet to get any time, and it is just a matter of time, to work on the "jet pump" that will siphon the water up to the boat, and then eject the water with enough force to propel the model forward and up onto the foils. This particular style of Hydrofoil, the inverted "T" foil also needs a gyroscope and "aelerons" to keep it from tipping over once it starts flying. Malin's test bed is practially a dinosaur. They used some very innovative ways to control the foils, however with todays helicopter gyros available it is much easier to achieve what Malin and his mates did with off the shelf products.
This is evidenced by Yoichi Takahashi's work in Japan
If you can't find his posts on the IHS BBs, http://www.bulletinboards.com/view.c...oils:%20Models
or,
http://www.foils.org/
Go to the bulletin board and look for,
"Introduction of my R/CHydrofoilsModels work" Yoichi Takahashi


He has graciously reposted some of his work here

The Gunze Saengyo PT 50 Super Comet RC model that was availabe from Japan can sometimes be found on e-bay. They seem to be coming out of Korea, and the last one sold for just over $500 US. The run times on this model were about 8-10 minutes.
I only ever saw one locally. And that person has dissappeared, no telling where him or his model have landed.

I have also got a rough set of frame plans worked up for the PT 50 using diagrams sent to me by Martin Grimm of Australia. I have frames cut, but again, time has prevented me from assembling the project to check for errors, and make adjustments or draw up a good working set of plans.
The PT 50 is a surface piercing "V" foil, and much like the Gunze Saengyo model, would need only power and steering to perform properly. If you like, I could forward what information I have on this boat also.

Let us know how you want to procede[8D]

[Edit]
The plans for the PHM series of boats that used to run out of Florida are available via
http://floatingdrydock.com/
the G series Patrol craft PHM2 or PHM6
http://floatingdrydock.com/G.htm
And the Hull lines Patrol craft HULL-PHM/4
http://floatingdrydock.com/HULL.htm

These boats also need to be gyro stabilized and there are innovative ways to power hydrofoils if you can't get the jet pump designed properly
Here is a look at one built by Ronald Swart in Holland and currently owned by "AntoinL", just scroll down a bit.

Hi All!
There is scheme of a tandem - drive gear for BABOCHKA-2 hydrofoil, and pic of it (one of propellers is removed). In the drive the angular gear is used.
