About this Plan

A-Hoy. Radio control sport seaplane model. For .40 to .61 power.

Quote: "I wanted a reasonably large aircraft, powered by a .61 engine, and with good wing area. I wanted it to be acrobatic to fly, allowing the pilot to do something more than just shoot touch and goes. I wanted it to be rugged to take the banging around that happens on the rocks and broken obstacles found along most lake shores. I wanted it to be easy to build and maintain and, above all, I wanted it to be fun to fly.

The A-Hoy does all of the above. When I set about designing the A-Hoy I used the basic premise that the hull would be simply a large float. The design on the hull would be exactly the same as the foam floats that I had been using for a couple of years. I looked back through past issues of RCM and other magazines to see what other flying boats looked liked and how they were set up, and found that everyone else had used about the same idea.

The finished A-Hoy looks very much like several of Ken Willard's designs, and well it should, because Ken is really the Grand Daddy of flying boat model designs.

A-Hoy is very rugged and is built to take hard knocks. Because most of the lake shores are less than clean, and because hidden hazards are always around, I recommend that you cover the bottom of the hull and the sides with lightweight fiberglass cloth and resin. A-Hoy was designed to fly on a .61, but after flying her for a season, I feel that if you wanted, you could do well with a .40. Naturally, the take-off run would be longer, but at an all-up weight of only 6 to 6.5 Ibs. (mine weighs in at 6Vz Ibs. and a wing area of 800 square inches) it can easily be flown with a lot less power than the Speed Webra puts out."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
