About this Plan

Hysteron Proteron. Free flight canard model, for 0.75cc engines.

Quote: "After building and flying a couple of Pegasuses (which flew charmingly, while proving that you can stall a canard if you're ham-handed enough) I decided to design my own, and arrived at Hysteron Proteron (which is Greek for back-to-front).

To avoid the fiddly trimming of a too-small model, I decided on a wingspan of 48in for a Doonside Mills to give a reasonably brisk powered glider. The other areas and proportions were worked out from Henry Cole's formulae for canards - as published by AeroModeller in a design series in the early 1950s.

Initial testing (including a 150-foot spiral dive into, fortunately, a bog) resulted in considerable re-design, including enlargement of the elevator - whose section was changed from flat-bottomed to SI 64009 - the addition of a skeg to increase fin area, lowering of the engine pylon and the addition of aileron tabs.

The result is a very safe and tractable model with a fair rate of climb, a slow, floating glide and considerable stability in wind (as proved at the 1975 Nationals).

Construction is quite straightforward: PVA glue was used throughout, on the original, with quick-set epoxy for wood-metal joints. Cut out the sides and rectangular formers..."

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.
