Top Flite Tauri - Radio control trainer model.
Quote: "HERE'S A MODEL with a purpose. First and foremost it has been specifically designed as a trainer for multi-channel radio control. Through the kit issued by Top Flite in the USA, it has already become world famous.
We learned of it first when designer (and then World Champion) Ed Kazmirski visited our offices during his demonstration trip to S. Rhodesia. Ed's design philosophy appealed to us in its purposeful approach, and earnest effort to salvage some of the 'sudden death' novice attempts to learn how to fly multi-control with contest designs. Tauri is small and therefore costs less to build than larger multi designs. It employs a relatively small engine (of 3.5 cc) and is therefore slower, yet no less efficient by virtue of the thick, semi-symetrical wing section. Above all, it is an easy model model both to build and fly. It is also a fully acrobatic aeroplane, though initially intended for six channel radio installations - rudder, elevator and engine.
For a first try at the multi game, this is about as much as one can handle. Installation capacity allows for all equipment ranging from the Super-Regen relay Rx to the latest relayless Superhets and a typical control system is shown on the plan. Since weight is a most important factor in a load carrying radio model, choose balsa carefully, assessing the density of the wood according to its purpose.
Construction notes on the plan explain the warp resistant self-jigging wing structure and fuselage assembly, but the builder can profit from extra tips on individual items. Since control depends upon them, the surface hinges should be free and allow 60 deg. motion in either direction. Use the herringbone stitch so well proved in control-line circles.
The engine will have a lot of work to do and will be running for long periods. Mount firmly with brass bolts (which shear in a crash) and don't forget the locknuts. Bearers must be liberally proofed against fuel seepage. Align the fuel tank with the needle valve body and keep fuel tube short. Use a fuel filter and make sure the weighted end of the syphon pipe has free movement in the tank.
On the radio equipment, be sure to make a neat wiring job. Skin off only enough sleeving to make the solder connection and insulate every joint with Systoflex or fuel tube. That demon vibration can affect reeds in a receiver..."

* 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.
