About this Plan

Breathless - Radio control plane for 2 channel RC.

Quote: "For small flying sites, this Half-A powered RC, is simple, strong, and highly maneuverable. And it is superb for a beginner. Breathless, by Ken Willard.

The objective was a rugged, reliable R/C model, suitable for sport or contest flying, powered by Half-A glow or diesel motor, and as simple as possible to construct. All of the flight proven aerodynamic design factors were listed and the design was laid out. All of the crash-proven structural strength features were incorporated into the detail construction of the model.

The result was a sheet-balsa fuselage and tail, silk covered, and a conventional built-up wing, silk covered, all held together with the finest shock absorbing fasteners yet devised - rubber bands. Bracing is distributed so the model will withstand hard landings easily, and only requires minor repair even after a crash due to malfunction (which might be mechanical, electrical, extraneous or human).

The model will recover from any flight attitude and assume normal level flight, just by neutralizing the controls.

Construction. The plans show the wood sizes. For a Half-A, medium hard balsa, except where plywood is specified, has ample strength, especially after the framework is silk covered.

Cut out the two fuselage sides from 1/16 x 5 sheet, cement the longitudinal and upright braces in place, and let dry. Note the downthrust provided for firewall mounted engine, as well as right thrust, accomplished by proper placement of the firewall braces on the two sides.

When putting the sides together, cement the tail block and escapement bulkhead in place first, This helps to obtain proper alinement. Next, pull the sides together and cement the cross braces in place where the leading edge of the wing is positioned, making sure that the sides are pulled in equally. Finally, do the same at the firewall, and this will give you the proper alinement to give right thrust.

Install the escapement and torque rods at this time, since it is easier to get inside the fuselage before the top and bottom sheeting is added..."

Hi Steve, Another Ken Willard plane here. This is Breathless from Model Airplane News, August 1957. Whole article and the plans are attached.

Notes

* 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.

Scaling

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.
