About this Plan

Jiffy Jet. Simple all-sheet model for Jetex 100 power.

Quote: "Try the new Jiffy-Jet. A tested, stable semi-scale job that is simple to construct and a snap to fly. By Dick Struhl.

As with full-size aircraft, jet propulsion is rapidly gaining a foothold as a source of model airplane power, bringing many new problems to the model builder. If you can recall the era of the late 30's, when gasoline engines were encroaching upon the rubber motor, you will remember we had the same situation. Different modes of power require different basic set-ups in the model, and it takes time and experience to learn, investigate and solve the various problems that arise.

The obvious points that you think of in connection with jet power are the lack of torque, the great difference between power-on and power-off adjustments, the great heat about the engine, and the fuel dissipation with its reduction of weight at the engine location. And these are but a few of the problems that face the embryo jet designer and model builder.

To get you started on the right track with jet models, we present this tried and proven,semi-scale model using the Jetex 100 as the power plant. The configuration of the model was taken from the DeHavilland 110 all-weather fighter. No attempt was made beyond that to follow scale - we altered the model considerably to fit modelers' needs.

Our model is, in effect, more of a powered glider than a flying scaler. But it is good looking and strong, and simple enough to give you quite an education in jet power.

The profile fuselage minimizes construction and leaves the engine readily accessible. The engine is located at the center of gravity and approximately at the center of resistance to minimize power-on and power-off differentials. The stabilizer is mounted high on the rudders, away from the jet blast. Construction is sheet balsa throughout..."

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.
