About this Plan

Raven. Simple 2 channel sport RC soarer, for slope or thermal.

Quote: "The main design requirements for this model were that it would have a great deal of free flight stability (ie we didn't want to have to fly it every moment) and that it would be easy to repair, just in case, after all with the current prices of balsa wood we can't afford to scrap everything.

Ye Editor thought that the design looked reminiscent of the old Keil Kraft Chief (oz9), which was very astute as the impression I wanted was of a 1950 vintage type glider. The basis of the Raven was actually a series of models I made (in those days they were never designed), when I was a member of the Beverley and the Blackburn Aircraft Clubs, many moons ago. This was in the era of the 300 ft. towline, and contests consisted solely of Open Power, Open Glider, and Open Rubber.

In those days I was too poor to give my models names, they were just the 'Rubber Job', or 'The Glider', but I ramble, so back to the Raven. This is somewhat larger than my 1950 models which rarely seemed to get bigger than about 5ft span, possibly because they had to be carried around on a Hull Corporation bus. But in these afiluent times when everyone has his own transport, size seems to matter little, unless you're stuck with a Lamborgini Urraco, so a 6 or 7 foot span sport model is quite acceptable.

The model as shown in the photos was built for floating around over Southern California, and it might be a little light for English breezes, so some suggestions for beefing up the structure here and there are given in the construction notes, which follow..."

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.
