About this Plan

Skeeter. Free flight sport autogiro model. For 1cc -1.5cc diesel power.

Quote: "Mark Sixteen in a long line of Autogiro experiments the SKEETER is a perfect beginners introduction to this branch of modelling. Designed by Den is Cooper and Ray Coles. HERE'S a model for everyman, beginner or expert, an Autogiro that might well reach the Tomboy (oz285) class of popularity. It has been developed to the stage where success is guaranteed for anyone able to build a reasonable model, and is certain to be especially popular with the many thousands of 1 cc diesel owners.
Full 1,400 word building instructions are issued with every APS full-size plan; but to give a foretaste of the simplicity of Skeeter operation, we quote part of the trimming gen which we are sure will be of interest:
This model was designed for the specific purpose of producing an autogiro which could be easily built, using a popular type of 1cc engine, and which could be flown with a minimum amount of maintenance work. In fact, tests have shown that the Skeeter can be flown in high winds which have grounded conventional types, even control line. However, before such all weather living is attempted, a little experience should be gained by flying the machine under calmer conditions. Remember that all control of this type really derives from the rotor. If after making tests you find that upon release the model tends to roll, either to right or to left, it means that one side of the rotor disc is not lifting sufficiently. Thus, if the model rolls to the left, increase the angle of attack of the advancing blade from -2-1/2 degrees to -2 degrees, using the flat board previously described as a jig. On all occasions, make sure that all three blades are rigged at identical angles. A sign of variation of rigging is undue oscillation from the rotor. It is hoped that readers who attempt this model will enjoy many happy hours flying off full tanks of fuel, yet finding their machine landing within 200 yards of the take-off point. The authors will be pleased to answer any queries if sent c/a the editor, and they wish to acknowledge and thank all enthusiasts who have contributed by their interest to the success of this machine..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

* 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.
