About this Plan

ROG. Simple rubber stick model for beginners.

Quote: "Getting Started in Model Aviation: ROG, by Walter Schroder. In this second installment you learn how to build and Fly a rubber-powered ROG.

Now that you have learned how to build with sheet balsa and make primary flight adjustments, by constructing and flying the hand-launched glider described in the August 1948 Flying Models, you're ready for our new project - a simple, all-balsa, rubber-powered ROG (rise-off-ground) model. You'll find this new plane just as easy to build as the glider, except for the wire fittings and the propeller.

Flight adjustments are different, because of the motor-power and the propeller torque (the tendency of the motor to turn the model opposite to the direction of the propeller rotation).

Like the glider, the ROG has four basic sections: (1) The wing; (2) The body or fuselage; (3) The vertical fin or rudder; and (4) The horizontal fin or stabi-lizer. In addition to these, we now have a fifth basic section, which will be included in all future models: (5) The power plant, or motor.

While the ROG is the most popular of all beginner models, there are no kits of the construction type available. You can however obtain finished, ready-to-assemble models Jim Walker's A-J Hornet and Megow's Cobra.

The flight adjustments outlined later in this article apply to both of these commercial models as well as to our own ROG, and will transform them from run-of-the-mill, up-and-then-down flyers to real flying beauties. As a matter of fact, we have had a 48-second flight on busy 34th Street in New York City with an A-J Hornet.

The only additional tools you'll need now are a drill which can take small bits (#55, etc) and a curved sanding block as shown in Fig.3c. The drill may be obtained at hobby shops - the sanding block can be made by yourself. You need this block to form the undercamber in a carved propeller.

Before starting construction, secure all the necessary supplies for your ROG, as follows (balsa unless otherwise specified)..."
