Merry Miller (oz9290)
About this Plan
Merry Miller. Free flight autogyro model for Allbon Merlin power. Rotor diameter 32in.
Quote: "Build this simply contructed 'giro for a new experience in model flying. Designed for the Allbon Merlin or enfgines from .75 to 1cc.
Although the writer's name is more generally associated with free-flight scale and tail-less models, we all have the urge, at some time or other, to build and fly something different. Just before the war the Cierva Autogiro rotary wing aircraft became a familiar sight in Britain and certainly paved the way for the helicopter of today.
From the model maker's point, of view the autogiro has one particular aerodynamic complication, and that is the difficulty of balancing out the lift of the upwind and downwind blades of the rotor as they rotate with forward movement of the aircraft. The model helicopter, with its vertical ascent and descent (we hope!) neatly slides round the trick asymmetry of lift which characterises the model autogiro.
However, the writer felt that plain straight up and down flight was likely to become rather dull, so consequently the autogiro was the final choice.
The model depicted here is the second of the series and virtually flew straight off the drawing board. With a little care and thought during the initial stages of test flying, a really reliable model, capable of flights in weather which would ground more conventional types, will be your reward. With the possible exception of the rotor hub assembly, the model is simple to construct and will stand up to really hard knocks..."

* 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.
