About this Plan

Guillotine 62in span Nordic A2 class FF glider. From Model Aircraft, March/April 1950.

Quote: "No wild claims are made for performance. After all, we did not get the Nordic rules until just before Christmas, and the weather has not been at all helpful since. However, the only points about which I am not absolutely sure, is the exact incidence of the tailplane, and the exact position of the CG. It must be appreciated that the ultimate success of a model in flight depends very largely on these two factors, and only after many experiments can one say with honesty which is the best CG position and tail incidence.

If I may do some crystal gazing for a moment. I would say that the progress of Nordic design will consist of perfecting the wing and tail incidence relationship together with the CG position. development of wing sections, the greater use of the tailplane as a lifting surface, the development of soaring and undulating flight (never to be confused with a slight stall) and finally construction and drag-reduction refinements.

Guillotine is a deliberate attempt to get somewhere in this respect, and great care has been taken to eliminate the hazards of rough seather flying, such as tow-line instability, lateral instability, sweeping down-wind and not turning back into wind, and so on..."

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.
