About this Plan

Guppy. Radio control sport model for .20 engine and 3 channel radio.

Quote: "And now for something completely different! Try John Rutter's 42 inch span flying win for .20 engines

During a particularly uninspiring meeting at work in December 1994 I 'doodled' this particular design on the minutes of the previous meeting. I must have been reminiscing about 'the good old days' of control line flying wings, with thoughts vaguely on the KK Talon (oz4398) crossed with a Warlord (oz12240). I wanted a flying wing with a bit of fuselage so that I could hand launch it much more easily than a pure wing. Throttle control would also be nice - at least I could then land it when I felt like it instead of waiting for it to run out of fuel - and I might want to fly it slowly, maybe, sometimes - well alright, long enough to find out if it would fly slowly because you have to write about these things!

Let's get started!

Anyone who flew a C/L combat wing in the late 60s or early 70s will recognise the wing construction, which starts with the production of the rib template in a bit of scrap 1/16 ply. This is used to make the 14 ribs - 12 from 1/8, and two from 1/4 in. Next I cut the 1/4 in material needed for the leading edge (LE) top and bottom, trailing edge (TE) and ailerons. It should all come out of a 4 in (medium to light) wide sheet with a little bit to spare. The wing is then built over the plan (cover it with a bit of Solartilm backing film or similar first, to stop it being stuck to the wing) by pinning the lower LE in place, followed by the 1/2 in square, followed by the ribs..."

* 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.
