About this Plan

Forte - Open power contest model for .40 size motors.

Quote: "FORTE is the result of two different approaches on how to get the most duration from a 10-second engine run; the first being an FAI sized model, the second a `medium' sized model, both powered by a K&B 40 motor. Each model had good potential, but unfortunately they both proved inconsistent - the smaller model was not rigid enough even though fully triangulated structures were used, leading to inconsistent climb patterns and wing breakage; the second model had a tuned exhaust system which gave a useful power increase but suffered from climatic changes, again leading to a poor power pattern.
The main consideration when designing Forte was structural rigidity and reasonably simple gadgetry; you will notice the very simple variable incidence tailplane (VIT) platform. This method of operation is preferred to the normal double-arm VIT which the author has found, to his cost, will operate under acceleration even with very strong hold-down springs. The pivoting platform is not affected in such a way..."

* 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.
