About this Plan

Small Stuff. Control line sport model.

Quote: "RESPONDING to every movement of the hand this little ship is as easy to fly as a Baby ROG. Designed to be flown indoors it is a swell job. Yet the same ship flies well out-doors when a smooth landing strip can be had to land and take off from.

Compact in design, this ship was made to handle easy with the aid of a spark retarder and an elevator up-spring. The spark is retarded to slow the ship down at which time the elevator up-spring causes the elevator to rise, this in turn brings the nose of the ship up and the ship mushes in to a slow landing. This is more desirable than flaps as they are hard to construct and the elevator up-spring works automatically and comes up as the speed of the ship is lessened.

The adjustment of the elevator up-spring is checked by holding the model outside window of a moving automobile. The spring should rise when the speed has fallen below twenty miles per hour. This can be checked against the speedometer. An Austin timer is used to retard the spark. This is done with the aid of a string connected to the timer and spark control lever. Slack in this line will determine the length of the engine run.

A low wing was used in order to give the ship a high cen-ter of resistance. When the power cuts. the nose of the ship will rise increasing the angle of attack thus causing the ship to slow down for the landing. The high stabilizer was used to get it out of the down wash of the wing. Only one side of the elevator needs be connected to the control plate for complete control of the ship. The elevator up-spring is connected to the other side of the elevator.

A large spinner was used to streamline the fuselage and reduce the drag of the prop hub, which is great on these high pitch props. Small wheels were used in order to reduce the drag as much as possible and pants were added in order to further this aim. The rudder was carefully blended into the fuselage in order to streamline the rear of the ship and to get a rudder that would not tear off if the ship turned over while landing.

You should now have a fair idea of the ship's performance and be eager to get to your work bench. This little crate doesn't take much supplies so you can probably use those left over from some past ship. The small size will enable you to assemble the ship in a few evenings at home. and when Sunday comes you can take her out and surprise the gang.

This time the wing will be made first. This can be made built up as shown on the plan or similar to an outdoor glider wing. The latter will give your ship a higher speed. However, many of us do not like this type of construction. After the wing is made lay it aside to dry and the fuselage can then be started.

Fuselage. Enlarge the crutch drawing to the correct size. Cut the bulkheads out and assemble in place. The engine bearers are then added. They should be cemented well as they absorb all the vibration of the engine. Put the top stringers in place now, and fill in with sheet as shown on the plan..."

* 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.


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.
