About this Plan
Evander. Towline glider.
Quote: "THE Evander is a sailplane of extremely pleasing shape. It looks right, and to quote an old aeromodelling maxim, most things that look right invariably are right! The model follows the latest trend of sail-plane design, incorporating a shoulder wing, high tail-plane, and a streamline aerofoil section fuselage. This latter feature gives the Evander a character and grace of its own.
The AEROMODELLER Staff conducted slope-soaring tests with the model, and were greatly impressed with its performance in view of the prevailing weather conditions. Stability was excellent. Gusty weather, with all the usual turbulence experience on hillsides, is a stringent test for any model in this direction, and the Evander came through with flying colours.
Flights of 200 to 300 yards were all that conditions would allow. These distances were covered in a fast glide with hardly any perceptible loss in height (the sinking speed is approximately 1-5 ft per sec).
This model is not for the lightweight enthusiast, having a wing loading of 10 oz / sq ft, but it proves beyond doubt the soaring capabilities of a well-designed heavyweight sailplane. It is worthy of note that during the test one rather too enthusiastic hand launch from half-way down the hillside resulted in the model clearing the hill and travelling a distance of some half a mile before landing in an allotment, which speaks well for Evander's performance.
The model, of orthodox construction, is comparatively easy to build and should be well within the capabilities of the average aeromodeller, providing he follows carefully the building instructions given on the plan..."

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.
