About this Plan

Fozzle. Unorthodox free flight model for Telco CO2 motor. A tailless biplane design.

Quote: "MANY PEOPLE have asked me, in tones of sympathy or outrage, why or even what is 'Fozzle'. The idea came to me, whilst inspired by the Rochdale Indoor Meeting. Not that I infer by this that the design is in any way their fault. As one friend said on seeing the contrivance: Well, you should feel better now.

Actually there is a certain logic to the design; it is light, 1-3/4 oz; it is very resistant to warps; has low drag; it is virtually crashproof. This is by design. That Fozzle also came out exceedingly stable, with a very good duration, and looks diabolical in the air, is pure luck. Purring round and round overhead, Fozzles have caused immense interest, though one in white with large green spots caused several requests that I repaint or remove it.

Cut and file an aluminium template for the wing ribs and cut out 32 ribs from 3/32 in soft sheet. Pin them together in two blocks of 16, and sand them down equal. With a razor saw cut the slots for the spars and leading edge. The spar slots are cut 1/8 x 3/32 in to allow for the slant of the ribs. Rub the plans well with a candle. Hopefully this stops the wings sticking to them. Cut and notch the trailing edges and pin them down. Place the end ribs in position in the trailing edge, with a length of 3/32 in soft in the bottom spar notches and line up the ribs, and pin down the bottom spar. Fit and glue all the ribs, spars and leading edge in place. All 3/32 in soft balsa. I use white PVA glue, but balsa cement dries quicker.

Cut the End Fins from 1/32in medium, with the grain vertical and laminate the Centre Bulkhead from 1/32in medium, with the outer layers grain vertical, also cut out the Elevons. Cut the Engine Mount, the Engine Mount supports, and the Tank supports. The Engine Mount is 1/8 ply, the rest scrap balsa..."

* 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.
