Forte (oz9513)

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..."
