Hoopla (oz5002)

About this Plan

Hoopla. Free flight gas pylon model.

Quote: "WHILE the battle rages between exponents of the pylon and non-pylon types of models, we take pleasure in presenting one of the season's top models in the former class. We do not wish to enter the controversy; but merely want to state that this little ship has been delivering the goods in Class A during past and current seasons. It derives its name from its designer, Eldred Hoopengarner, one of the top free flight men in the northern Ohio area.

Hoopla features a foolproof dethermalizer which really does the trick. The superiority of this type of timing device lies in the fact that it does not alter the model's tail adjustment.

A simple and unique type of construction makes Hoopla a desirable ship for your build-ing schedule. The radial mounting of the engine and removable ignition unit are unique. The concentration of weight and strength at the front of the model makes it highly resistant to damage when striking another object.

Let us also call your attention to the fact that our plans are presented in such a way that no drafting or enlarging is necessary for the model builder.

To date four of these models have been built using different classes and makes of engines, and all have had the same superb flying characteristics.

Study the drawings before starting construc-tion. Using the dimensions given on the drawings, assemble the crutch on your work board. As this is the main section of the fuselage, be sure it is correct and well built. Leaving the crutch on your work board, starting from the front and working toward the rear, build the bottom section of the fuselage right on the crutch.

When this is completed, remove it from your work board and build the top section in the same manner. Next fit in the piece of aluminum tubing for the dethermalizer, cementing it well. At this point the fuselage will be diamond shaped. Now cut the three pieces of 1/32 in flat for the inside planking and cement in place. The pylon stiffener is next cut from 1/16 in aircraft plywood. Cement it in place, making sure it is perpendicular to the crutch..."

Quote: "Here's an article (with plan) from the Jan. 1948 Model Airplane News. It's a 46 inch wingspan pylon type. Design is by Eldred Hoopengarner. Drawing and article are by John L. Mackenzie."
