Single Stick Pusher (oz16060)

About this Plan

Single Stick Pusher. Simple rubber canard pusher model.

Quote: "CHAPTER 2: SINGLE-STICK OUTDOOR PUSHER. THE pusher airplane is so called because the propeller, being in the rear, pushes the model through the air, instead of pulling it as in the case of tractor models. Many pusher models have proved successful at national meets recently, and it would be difficult to say which type of model airplane is more popular.

The model given here, while rather complicated in design and construction, embodies practically every detail found in pusher models, and has been chosen to represent this type of model because of this fact, plus its superb flying qualities. Each step in its construction should be carefully followed by the beginner, as many seemingly unimportant details in its design prove of utmost importance when the model is launched.

MOTOR STICK. The motor stick of this model consists of a 1/4 x 1/4 x 24 in balsa piece. Study the plan of this stick. Note that its direction of flight is opposite to that of the tractor models. The regulation propeller bearing can be purchased or made. (See Chapter 6: Propeller Bearings.) This is cemented and bound with silk thread to the end of the motor stick on its under surface. When in position, this end becomes the rear of the model.

At the opposite or front end, a nose hook is cemented over the end of the stick, which becomes the nose or forward end of the motor stick. This nose hook is similar to the regulation rear or end hook of the tractor model, except that it is attached differently. Its function, however, is the same as a rear hook. This nose hook can be bent from No.9 piano wire, as shown in the plans

A can hook is provided to hold the rubber motor in place on the stick. It can be bent from No. 8 piano wire, as shown. The nose hook is cemented in place on the end of the motor stick, while the can hook is fastened in the same manner to the center of the stick.

WING. The wing requires two spars, two wing tips, and thirteen wing ribs. The leading and trailing edge spars are duplicates, both being 1/8 x 1/4 x 24 in long. They are cut to size from balsa wood, and tapered as shown in the plans under 'Camber of Wing Rib.' The thirteen wing ribs are 1/16 x 1/16 x 4 in balsa wood. While the distance from the inside of the leading edge spar to the inside of the trailing edge spar is only 3-1/2 in, the ribs should be cut 4 in long to allow for their necessary wing camber. This is shown in the plans under 'Camber of Wing Rib.' A single piece of 1/16 sheet balsa wood 1 inch wide should be soaked and bent to proper shape, and the ribs are cut Mg" wide from this piece. Each rib will then have the same bend as all the others... "
