Canary (oz11165)

About this Plan

Graupner Canary. Radio control sport model, for electric power. Canard pusher design. Wingspan 1000 mm.

Quote: "The overall layout of the CANARY takes it out of the run of conventional model aircraft. Construction is relatively simple, but if you are a beginner to model building we still recommend that you construct and fly the model with the help of a skilled model maker or an experienced model flyer. The building instructions deliberately do not include stage photos, our intention is that you should study the plans and learn how to 'read' technical drawings, ie the method of gleaning information from them. The plan is drawn full-size, so the dimensions can be checked and measured directly from it.

The model can be flown using nothing more than a low-cost X-306 radio control system. The CANARY looks great in flight, and its performance will delight any modeller.

Building and flying several models of this type as a group activity is a wonderful way for youngsters to gain their first experience of success in modelling

The canard principle: The world's first powered aircraft - the 'Flyer' designed by the Wright brothers - was an example of this layout. Subsequently it became normal to describe aeroplanes of this type as canards (French for duck), because such aircraft have some similarity with that bird when flying. The forward flying surface (the canard itself) of this type of aircraft is much smaller than the main wing, which is located towards the tail The canard is rigged at a larger incidence angle and supplies higher specific lift. If the model's nose is raised towards the stalling point, the airflow over the canard always breaks away first, which means that the lift of the main wing is maintained. Compared with conventional models, this means that the dreaded 'tip-stalling' is impossible, and the danger of an abrupt loss of height caused by a complete breakdown of wing lift is eliminated.

A further advantage of the canard principle is the unusually short fuselage, which helps to minimise airframe weight.

The longitudinal stability of the CANARY is high enough to allow the pilot to demonstrate the aerodynamic principle simply by stalling the model deliberately.

Fittings and accessories: To control the model you should use an FM radio control system such as the X-306 or X-412 to mc-24. Please refer to the main FS catalogue for more information about RC systems and components, or read the operating instructions supplied with your radio control system if you already own one. We strongly recommend that you obtain all the accessories required before you start construction, so that they can be installed at the appropriate stage of assembly..."

Quote: "Hi Steve & Mary, I recently bought the above kit off fleabay and thought you may want to add the plan onto Outerzone. There are three sheets - the plan, and two sheets of written instructions (in 3 languages). Technically the formers are there, as the German instructions include a parts layout, though not at full size. If you do include it, please credit Gene (rchopper56) for his superb work in restoring my poor quality scans! Rgds"
