About this Plan

Kobra 20 B. Radio control sport model. Wingspan 1065 mm, for 25 engine.

Direct submission to Outerzone.

Quote: "Hello Mary, Hi Steve, In Allt om Hobby nr 03/1991 a plan was published called Kobra B. It is an enlarged version of the Kobra (oz16104) probably by the same designer (Lars Holmgren). Over at the AF site there is https://aerofred.com/details.php?image_id=101562 which is not the original, but was used as a template to create this attached plan. This plan has parts, more detail and refinement but it is unclear if it matches the original. Hopefully someone can provide the article so it can be checked.
Also attached you'll find a PDF file containing all the parts necessary to build a Kobra B spread over 6 tiled A3 pages. Those who want to create their own pages can open the SVG file.
Thank you for all the work you do for us. Greetings from the Netherlands, H.J. van Tol.

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.
