About this Plan

Beginner's Goat. Contol line trainer model.

Quote: "Simple Control-line Trainer for Clubs and Instruction Flying. Beginner's Goat, by Roy L Clough Jr.

THIS control-line trainer, together with the .operating instructions which go with it, has been worked out carefully to guarantee absolutely good results to the newcomer.

This Goat is the result of a study of the factors involved in building, flying and maintaining a plane which can always be counted on to deliver the goods.

No assumptions have been made that the builder will fly it from smooth fields and only on calm days. On the contrary, we expect it to be treated roughly, flown in. relatively high winds from gravel pits and deep grass, in hot weather and in cold, and perhaps in the rain. If a model can perform well under these conditions, and incur no major damage, then it is a 'good' plane. The Goat is good.

At this writing the Goat has more than 600 flights averaging better than five minutes each, or a conservative estimate of more than 50 hours in the air. Non-flyers have learned to fly it, in about a dozen laps apiece and nearly every member of the Bell City, Bristol, Conn Aeromodelers has flown it.

The high spots of this design are the wing section, tail configuration, landing gear and engine installation. The airfoil is a section worked out by the writer over a period of years by the effective cut-and-try system. The tail plane offers positive control without trickiness, the landing gear can 'take it' and get the ship off ground too rough for most models. The engine installation, being sealed off from the rest of the ship can be dunked in a can of kerosene for cleaning if the plane has nosed over in sandy soil.

Despite the square lines and generally boxy cone struction this model flies in the neighborhood of 50 mph with an O&R .19. With a trick prop and hot fuel it has hit over 60 mph.

To begin construction, select two pieces of 3/32 sheet balsa, two inches wide, for the fuselage sides. Cut one piece to size and use it as a pattern for the other. The heavy nose block and wing mount block are cut from thick plywood, or soft pine, and are 1-3/4 in wide. Cement the two sides to these pieces after installing the carriage bolt wing stud in the smaller block.

When dry, pinch the tail ends together and tack-cement. Another 3/32 sheet of balsa is laid on for the bottom fuselage covering, then trimmed to shape, Use short bits of scrap cross-wise to cover the sharply curved section near the tail. Install the tail wheel, using a small block of pine to hold the wood screw behind the balsa covering..."

Notes

* 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.

Scaling

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.
