Gannet. Radio control slope soarer model. 75 inch wingspan, wing area 50 sq in. For 2 channel radio.
Quote: "FSS Gannet. Build your own slope soaring seabird with our 'Sula Bassana' plan, designed by Chas Gardiner.
The idea of slope soaring models of birds, reptiles or bats is not new and some pretty ingenious creations have graced the skies. Nothing evolves in isolation and various ideas have hatched out, and so the FSS class (models of creatures , originally covered in Feathers, Scales or Skin) has obtained a wider recognition.
Conway Jones inspired some interest in this direction with his excellent gull, aired two years ago in the Isle of Man. This delightful model may have been influenced by the birds made by American, Martin Smith for the film 'Jonathan Livingstone Seagull' which, unfortunately, I have not yet seen. Perhaps our friends at the BBC can rectify that?
Anyway, the Gannet, or Sula Bassana to give it its Latin name, seemed a worthy project since the proportions appeared to lend themselves to two channel aileron/elevator control. Alan Willows, who created the Golden Eagle seen in 'From Up Here' last year, helped with some proportion research, and using the epidiascope, the bird was drawn out. This one is to eggsact scale.
The original elevator looked about right and it was intended to use a clear plastic fin for lateral stability, but there was a long way to go...
This will not be a first model, and the construction notes are not intended to be too precise, only as a guide to the way in which it can be done. As I said about Conway's Gull, the model is not so much a construction as a sculpture and in this case even more so.
Here we go. Trace the outline of elevation and plan view, and transfer to a block of expanded polystyrene foam. Cut carefully to outline using a hotwire clamped vertically..."

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.
