About this Plan

Gyrolator - Free flight autogyro model.

Quote: - "Looking for something new to build? Then try this wingless Autogiro! by Paul Del Gatto ...We will admit that we were some-what dubious about its success, in view of the fact that our design totally eliminated the use of a wing. Many years ago we had enjoyed some mea-sure of success with Autogiros, but not without the aid of a small wing surface. So to us this design presented a new challenge.
Admittedly the plane did not fly 'right off the drawing board' - we hadn't anticipated it would. However, after several flights we began to re-solve the difficulties and improve its performance. Torque appeared to be our major problem and it wasn't until we minimized its effect, by using low-pitch props, that we were able to control the steep left bank of the model.
Other adjustments, such as changing the rotor blade angles and slightly increasing their dihedral, were also made. We found it necessary to add some negative incidence to the stab and move the CG slightly rearward to get the giro in best trim..."

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.
