BT-20 and BT-40 Aileron Wings (oz9206)
About this Plan
BT-20 & BT-40 Aileron Wings. Plan showing a modified wing design for both of the previously published Primary Trainer PT-20 (oz8014) 48in and PT-40 (oz8015) 60in models, thus converting them from PT primary trainers into BT basic trainers.
Note This is not a complete plan, this here is just the wing mod.
Quote: "Our September 1985 issue featured a highly successful R/C design for the novice R/C student which is dead simple to build and extremely forgiving to learn to fly. We urged you to bring that simple construction article to the attention of beginning R/C students . . . and a major kit manufacturer plans to have a kit available about the time you read this that is based on that PT design. This design accepts a broad range of 2-stroke engines as well as the new wonderful sounding 4-stroke engines we all enjoy so much. The kit manufacturer asked that an aileron equipped wing in each of the two sizes be developed to make the models more advanced and more broadly appealing, and that's what we present in this short article..."
Quote: "Restored text and some geometry, before placing it on a 36-inch page."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
