About this Plan

Cloud Chaser. Rubber sport model. Twin pusher design.

Quote: "Cloud Chaser. A 1931 twin pusher design by Joseph S Ott. Drawn for the NFSS by Don Farnsworth."

Quote: "Chapter XXXIII. Cloud Chaser. Outdoor Twin Pusher- Duration.

For duration contests out of doors, the Twin Pusher is used most extensively. In fact, when outdoor contests are an-nounced, it is usually assumed that a Twin Pusher will be used, unless otherwise specified, such as fuselage types, scale models, etc. All outdoor duration records are held by this type of model.

Various kinds of designs have been used at different contests, and the models have been built extremely light, to such an extent that it becomes a matter more or less of luck when flying this type. In other words, any boy with a fair amount of model experience can build a good Twin Pusher of a specified weight. The arrangement of the propellers and rubber bands may be approximately the same on ten different models. The weights may be the same with slight variations in wing curves and wing areas. Of course, good workmanship and good model engineering go together for successful flying, but it has very often happened, and it probably will in the future, that in some cases the poorest models have flown the best. This may be considered due to various things, the condition of the air, the time of day the model is flown, and if the model gets a good start and rises steadily.

As a general rule, however, the best model builders that apply all the theories in the most efficient form, usually turn out the record breaking models. Luck always enters into it, but it may be considered the exception rather than the rule. It is mentioned here because it takes place now and then, and to understand the conditions as they might occur, is to one's advantage so that all precautions might be taken into consideration..."

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.
