About this Plan

Co-Ette. Free flight sport model for either CO2 or rubber power.

Quote: "Co-Ette. CO2 or rubber powered model. Powered by Herkimer or US Rubber Company's T-56, this good looking flyer is a natural. By Jay Holmes.

To see if there was any notable difference in CO2 powered models this ship was built for both rubber and CO2 power. The results showed that although the CO2 version with Herkimer's carbon dioxide engine is slightly heavier it has good performance and the duration (in glide) is comparable to the rubber job flown on US Rubber Company's T-56.

This little ship is suitable for beginners and experts alike, as it is simple but efficient.

As the plans are full size there will be none of the usual troubles in enlarging. Pin punch all formers, bulkheads, and outlines on sheet balsa of required thickness. When making wing ribs pin punch one on 1/16 sheet pine and use this as a template for the required seventeen. Dash lines on the wing rib show where slots are cut after constructing the wing and should not be cut out until then.

When the formers are made, place the plan on a soft pine board and rub thoroughly with soap or place a sheet of waxed paper over it to keep any glue from adhering to its surface. Before laying down the longerons soak the two 1/8 sq strips that are to be used for the bottom longerons in warm water for about an hour. This will permit you to bend them quite easily to the shape shown on the plan.

In the meantime construct the rudder, as it will require about half an hour and will keep you busy. Pin the 3/16 x 1/8 x leading edges in place. Glue in position the sheet tips outline. Next cement the trailing edge..."

* 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.
