Windward (oz7879)
About this Plan
Windward. Radio control sailplane model. 72in span, 532 sq in wing area. For single channel or multi RC.
Later kitted by Dynaflite.
Quote: "Windward is a high performance sailplane that has been successfully built and flown by Modelers/Sportsman with little or no experience in radio control. With this airplane the expert can win contests or the beginner can teach himself how to fly. Windward can be launched with a hand held tow line just like any free flight model glider. Catapult launch, airplane tow, power pod, power winch and slope soaring have all been successfully performed.
Regardless of where you live or the size of your flying field there are no problems flying Windward. One of the launching methods will suit your area. The ideal pilot position is flat on your back on a patio lounge with a cool 'coke' close by. Add some blue sky with fluffy cumulus clouds and you are ready for flying fun limited only by the patience of the man who wants to fly his plane on your frequency.
Wing. This wing is designed for full aerobatic competition. Note the double spar shear webs out to wing bay number 5 and single webs out to bay number 9. Be sure to put all the shear webs in place. Don't get lazy or try to make the wing lighter. These webs are the main strength in the wing design. Without them the top spar will be free to buckle in or out when you pull out of one of those accidental dives..."

Hi, Steve and Mary. Nice to see the Windward finally appear on your site! I built my first Windward in 1974, and flew it for seventeen years before straining it through an oak tree. Since then, three more Windwards have been built from my ratty, 42-year-old plans. While it's certainly not competitive anymore, the Windward is one of those classic designs that should never go away. It's relatively easy to build, has plenty of room for any radio equipment, and is still an excellent trainer. Later kit plans show lightening holes cut into the aft end of the fuselage, and I took things a step further on my latest Windward by going with a built-up horizontal stabilizer. I also incorporated a light-ply fuselage bulkhead at the wing's leading edge, which will prevent the fuselage sides from splitting aft of the cockpit during those less-than-perfect landings. Still, it's a pretty robust airframe overall. Attached is my current Windward, taken atop my local slope [more pics 004]. Hopefully, we'll see more Windwards flying soon. Thanks again for all the hard work on the site!Moeregaard - 19/07/2016

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.
