I had just spotted the BMFA Challenge when Stefano mentioned he would be interested in developing an activity around rc model planes at the Mosaic Clubhouse and that Make Me Smile Again could be a way of financing such a project.

So Stefano and Victor filled in the application form for Make Me Smile Again and on the 9th of February Stefano got a confirmation that they had agreed to support the project with £746 🙂

In the mean time, I got a chance to talk with Lucien Cabrol, the inventor of the COLAB Concept (French).  He thought this concept was well adapted for such a project  and gave me some useful guidance.  The concept uses wings that join at their tips, having two major benefits: increased strength by triangulation and being far more efficient than a wing of same width.
More efficient in that it can get better lift, can fly slower and can fly faster that a traditional wing and still remaining more stable, and the best of all, such a wing is still simple to build using the same techniques as for a standard straight wing.
