About this Plan

A Wonder. An A/1 Nordic glider using Jedelsky wing construction. All-sheet wing.

Quote: "All balsa A/1 Wonder glider is easy to build and trim for those long silent flights. A/Wonder, by Bob Stalick.

A/WONDER is a wonder of a glider. Picture it gracefully wheeling overhead in the warm summer air, silhouetted against the high cumulus clouds. Soon the dethermalizer fuse burns through and the stabilizer pops up, settling the model gracefully to the earth.

Imagine that this model is yours and the flight just completed is your first. The wonder of it all is that it can be yours by just several evenings of pleasant work and around $2 in materials. If the picture of your own creation hooking into a thermal is appealing, then let's get started.

Construction: The A/Wonder was designed to use the efficient Jedelsky-style (all balsa) wing and stab, and further designed to utilize all the required balsa wood with a minimum of waste. Before you begin, take a close look at the bill of materials at the end of this article to make sure you are buying the right sizes and weights of wood. C-grain balsa is specified in most cases. This wood can be determined by its mottled appearance. I strongly recommend using Tite-Bond or Sig-Bond in all construction except wire hooks which should be glued on with Ambroid.

Wing: First, carefully cut out eighteen 1/2 in balsa wing ribs according to the pattern on the plan (a hard cardboard or plywood pattern will help to keep them uniform). Be certain not to cut off the X-tabs at this time, as they are very helpful in construction.

Next, carefully cut the 1/4 in balsa sheet in half lengthwise. Then, cut one of the 1/4 sheet strips to a length of 30 in (this is the leading edge of the wing center panel) and glue a 30 in length of 1/4 x 1/8 spruce to the front of it..."

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.
