About this Plan

Joker. Radio control sport model. Wingspan 910 mm, for 1/2A power.

Quote (through Google translate): "Joker was born a long time ago, in 1976 to be precise. I had read some articles on 1/2A in US magazines that year and I thought that this category would excite the French. I designed and built a first prototype during the winter of 1976, it flew and showed that a model of this category does not have to be loaded at dm2. Indeed, out of the workshop at 450 g, it was very pleasant but at more than 520 g it was unmovable! The model as designed flew fast but above all landed quickly and therefore required precise piloting with a ground contact, as smooth as possible because, it had no gear. The final model had to be more solid, fly more slowly, and allow a more important wing load.

The second prototype was born in 1982 and used all the lessons learned from his older brother. One of the essential goals being that Joker would serve as a 'half-time' or 'relaxation pose' to pilots who master a winged model. He had to be able to go further, for experienced pilots who want to break the baton in reverse flight, for example... "

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

* 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.
