About this Plan

Eclipse. Radio control powered glider model. Wingspan 78 in, wing area 660 sq in. For electric power with Mabuchi 550S motor and Al-Tec 3:1 gearbox.

Quote from ad: "Airtronics Eclipse, our first electric powered sailplane kit, gives you the best of both worlds. Ideally suited for beginning sailplane enthusiasts and advanced sport flyers, the Eclipse offers advanced aerodynamic design and engineering to ensure uncompromising soaring performance.

This new generation in sailplane technology continues Airtronics' quality kit tradition by combining the advantages of electric power and soaring flight. It's quieter and easier to use than gas engines, it's suitable for smaller fields for greater flying site flexibility, and it eliminates cumbersome hi-starts and winches.

The Eclipse features a sophisticated gear reduction system superior to direct drive units. This gearing provides for a higher rate of climb, additional performance and more altitude per charge.

The Eclipse utilizes a folding prop that produces longer flights by eliminating prop drag. The easily transportable three-piece wing incor-porates built-in wash-out that provides excellent turning characteristics and prevents tip stalls. A high performance semi-symmetrical airfoil offers docile handling characteristics for beginners and first time electric flyers.

Available in two kit configurations, the Eclipse is simple and easy to build with detailed full size plans and fully illustrated instruction manual.

The Standard Kit comes complete with all necessary hardware, hand selected wood and machine cut precision parts. The Deluxe Kit includes a high performance Mabuchi 550-S electric motor for power and endurance, Al-Tec 3:1 gearbox, Master Airscrew folding propeller, and Goldberg spinner. Both kits will accept optional high performan motors and battery combinations.

The Eclipse combines Airtronics' uncompromising sailplane design and structural integrity with the ease and superior performance of electric power. Get the best of both worlds with Airtronics' total Eclipse."

Quote: "Greetings from Michigan, USA, once again. Please review the attached scanned Eclipse plan and see if it is useable... It is a great old design that needs to be shared. Also attached the rib profiles to complete your files. Thanks again for all of your work on behalf of us balsa builders. Craig, Battle Creek"

Update 23/10/2023: Added kit instructions, also redrawn ribs file, thanks to NX13688.

Quote: "Hi - I scanned the build manual from my Airtronics Eclipse kit & made a clean line drawing of the ribs. Enjoy!"

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.
