Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsI think the parts list is missing so you will need to get the parts thickness from the plan and you have to guess the kind of wood you should use. Also, I wonder about the front wing which is a flat sheet. Do not canards need a front wing of a higher lift efficient than the main wing?

Got parts list now, see supplement article file.

Wow. Every weird configuration you can imagine, all wrapped up in one model, a double delta canard with engine mounted in a pod above the wing. I built several canards back in the day and they all flew with no airfoil at all, rubber powered with a pusher prop. The canard on this one is pretty small, probably only used for trim. I think it would fly fine without it, using the elevons for UP trim. Plan shows a little up trim in the canard, probably needs more, an interesting project, will help if you can find someone who understands German. The Pee Wee 020, introduced about this time, was my first successful model engine, bought for $3.95 with my paper route money. It had a whole lot more power than expected, and I lost mine to a thermal on its first flight. I had a rubber powered model of about 3 ft span, so I chopped the long nose off and mounted the Pee Wee. There was no good way to adjust the run time without modifying the tank, and I tried to use just a small amount of fuel. Didn't work of course, and it was a very small speck by the time the engine quit. Thermals took it ever higher and I never did see where it landed in the vast expanse of the old Napier Field Air Base. Most Pee Wee engines were sold in a plastic Pitts model, probably the worst flying of all the Cox models, it would fly about as well if you shortened the lines and just slung it around. But it made the Pee Wee engines available real cheap the day after Christmas after the Pitts had been destroyed. This model might make a good electric, would need a high RPM motor for the small prop required, elevons for control, maybe just trim on the canard.

Thanks for the article, Steve! I just had a quick read through it. It´s mostly detailed building instructions. The model seems to be fairly easy when it comes to the center of gravity and longitudinal dihedral.
Most interesting are the introductory lines: The author foresaw a 90% share of future aircraft designs in canards and flying wings. Also there were some expectations for nuclear powered aircraft. History has proved all of this wrong. Not too bad when it comes to nuclear powered aircraft. :D

I see this model with a small ducted fan. Fast and maneuverable.

* 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.
