About this Plan

Good Knight. Radio control sport model from 1961 AM Annual.

Quote: "Good Knight. A good looking, rudder-only radio controlled aircraft!

The principal objectives in designing this model were to develop an easily controlled, realistic flying, attractive and [unclear] airplane with no fancy frills which could hinder performance. Construction, simple but sturdy, reflects the results of not only our own experience but those countless radio control enthusiasts with whom we consulted. The size is convenient; neither too small nor too large, with a projected wing area of 590 square inches. The craft weighs more than the average radio controlled model of this size - Good Knight is not merely a radio-controlled free flight type. Speed under high power is moderate while the [unclear] is average. When the slow speed signal is transmitted the aircraft responds immediately without signs of any annoying floating tendency. Glide without power is fast but smooth and flat. Landings are a pleasure with a long fast approach.

Any glow plug or diesel engine of from .14 to .23 cubic inch displacement can be used in this model. The prototype is powered with a 19. A single channel Aristo-Craft TRR Rangemaster Tone Receiver is used in conjunction with a Babcock Mark II compound, self-neutralizing escapement for rudder control. A Babcock Universal Engine Control governs engine speed. An Aristo-Craft Rangemaster Tone Transmitter performs well with the receiver.

Construction can be started with the fuselage. Cut sheet balsa sides accurately to shape. It will be necessary to butt join 1/8 balsa to form correct height of fuselage. Cement 1/4 in square reinforcing strips to sides, set aside to dry. Cut bulkheads to shape, cement them between fuselage sides. When dry, carefully pull fuselage sides together at rear. Wet sides slightly with water if they resist bending.

Use clamp or pins to hold sides together until cement dries. The engine mounts are rigidly installed at this time. Add plywood brace to side of mounts. Cement sheet balsa nose doubler pieces in place. The nose area must be as sturdy as possible in order to provide adequate support for the nose gear..."

Update 14/04/2013: Have now re-scaled this plan up to full-size at 60in span, thanks to MarcBird.

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.
