Quote: "General Information and Pre-Construction Note:

The Customized Ringmaster kit was developed and produced to help model builders create their own personalized model and also to stimulate original design thinking. On the plans appear many different wing tips, tail surfaces and other design features which can be used in any combination. Since the basic design of the Ringmaster is retained, excellent performance is assured, plus whatever the variation of the design adds.

For general assembly and construction procedure, use the Ringmaster plan appearing on the right. Instructions for individual suggested models can be followed as given or adjusted to suit the modeler's own preference. Each design unit (wing tips, tail, etc) is complete with its own assembly sketch and instructions. Reference is made to them in description of models described on plan.

There are certain rules that apply to all models: They must balance nose down on front control line; wing and tail surfaces must be aligned properly to each other when viewed from front or top; wing and tail surfaces must be free of warps. Check controls before each flight for free, easy movement.

Examine the plans carefully, including the various design units and then select the model design you wish to build. We will welcome a letter from you on your experiences with the Customized Ringmaster kit and in return we will mail to you (no charge), at your request, our booklet - Model Building Secrets - which contains hints on covering and finishing, general construction, engine operation, and many other subjects; also our complete catalog.


Ringmaster Flying Man is one of the most colorful and unusual type of control line models over devised. The article below which has been re-printed from the 1962 edition of American Modeler Annual (with permission of Conde Nast Publications) just about covers the transformation of a standard Ringmaster to a Flying Man. In addition to the unusual appearance of the model, the flying qualities are just as startling! The Ringmaster Flying Man can be made to do the Saber Dance, in which the weight of the model is balanced by the thrust of the engine, resulting in the model hanging vertically and virtually motionless on the end of the flying lines, as explained in the article.

The variations of Flying Man are endless. They can, of course, be changed to flying women too, or you can use any comic strip figure as a head, or you can take a photograph of your favorite (?) person, whether it be your girlfriend or any relative and trace the profile off the photograph. If necessary, cartoons or tracings can be enlarged to exact size desired by any photostat house. Duplications of dress, suit, or shoes can be made following the same general pattern as designs shown in article. The sky and your imagination are the only limits.

Cut the 1/2 in balsa to proper length to fit head shape and cement together to form necessary width. Trim off side to match curve of top front of fuselage, then cement securely in place. Although magazine article calls for full height plywood doublers, we recommend that the doublers furnished in the kit be used due to the excessive weight of additional plywood.

Transfer drawing of head on plan to fuselage with carbon paper, then cut it out. Cement doublers in place as described in Ringmaster plan. Use 5/32 x 3 x 20 for stabilizer and 5/32 x 3 x 24 for elevator and rudder. Slot for stab shown on #1 fuselage drawing. Use 5/32 x 2 x 24 between wing and stabilizer. Cement 5/32 x 3 x 24 and 5/32 x 2 x 24 together to form 5 in wide sheet. Cut 4 pieces 6 in long and cement 2 sections together (seams alternating) to form double layer sheet, to be used for hands.

Since carved wing tips are not used, strengthen tip by cementing 3/32 sheet balsa to each tip against rib 10. Install landing gear as shown on detail note. Balance of construction is according to Ringmaster plan and magazine article... "

* 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.
