About this Plan

Buzzer. Free flight sport model for CO2 power.

Quote: "Buzzer, by William Winter. Slick free-flighter for the new intermediate size CO2 engine. You can convert it to realistic rubber model. Has looks, good performance.

THE Buzzer is a 120-square-inch sport model designed expressly for the new Buzz CO2 motor. With a bore of 3/16 in, the Buzz is larger than the Campus A-100 with its bore of 1/8, and smaller than the OK which has a bore of 1/4 in. The Buzzer is a medium-sized ship as CO, jobs go, spanning a trifle under 30 in.

Construction is orthodox. The fuselage is a box assembled from two side frames of 3/32 square balsa. The front end of the fuselage is made from 3/32 medium-hard sheet balsa. Each of these sheet-balsa side pieces is built in as part of the side frame. The 1/16 thick plywood firewall for mounting the engine is glued to the front edges of the side frames when the sides are joined together.

If you will look closely at the view on the plan it will be noticed that the frames are pulled in slightly toward each other. A light rubber band wrapped around the nose will hold the sides in position while the firewall is being glued. A bulkhead is inserted inside the nose section as shown in broken lines on the plan. This bulkhead is cut from 1/16 sheet balsa with the grain running across the fuselage.

The top and bottom of the nose is made from 1/16 sheet balsa with the grain running across the fuselage. First glue one end of these sheet pieces then, when dry, bend down the sheet and glue in place.

While many builders simply glue these small engines in position, the Buzz on the original model is bolted in place. The sides of the fuselage at the very nose are extended by small pieces of 3/32 sheet balsa, trimmed to match the contours of the outlines of the fuselage.

The tank for the engine is mounted by means of two partial bulkheads made from 3/32 sheet. One of these bulkheads is glued in place between the cross pieces at the station at the rear of the windshield..."

* 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.
