About this Plan

Soar Birdi. Radio control sailplane. Wingspan 78 in, wing area 624 sq in.

Quote: "Building Notes. The Soar Birdi has been designed as a sturdy, stable thermal flying sailplane ideal for the novice or experienced sport flyer. Utilizing a high-lift polyhedral wing, the aircraft may be flown off a high-start, winch, a local hill under minimal wind conditions, or by using an .049 engine.

For simplicity in construction as well as to minimize drag, the Soar Birdi may be built with an .049 engine mounted onto the nose of the fuselage by adding an 1/8 ply bulkhead provided in the kit. If you wish, the sailplane can be built with the additional bulkhead. Then the balsa nose block can be mounted to the bulkhead with 4 screws from the inside. With this arrangement, the nose block can be removed when you want to fly it up with an engine. Or, the nose block can be replaced when you want to fly it off a high-start, winch, or use it as a slope soarer.

If the sailplane is to be built for use with the power assist, the front of the firewall should be sealed with a coat of resin to prevent fuel penetration. A fuel tank/engine mount should be used to mount the engine onto the firewall.

Please take the time to read through the entire building notes first. Then, get out your pins, Xacto knife, and glue. It's time to go to work... "

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.
