About this Plan

Jupiter Moon. Competition HLG model.

Quote: "PLAN OF THE MONTH: Ed Berray of Vancouver, Washington has made quite a name for himself locally with his abilities as an indoor flier. After years of improving his indoor glider capabilities, he designed an outdoor glider that looked similar to this month's model. It first saw the rigors of competition in 1995. It was at one of these 1995 meets that glider guru Mark Sexton saw the model and determined to make it his next winner.

Mark decided that the model needed to be named something other than Ed Berray's Glider, so he came up with Jupiter Moon. I'm not sure just what the origin of this name is, and knowing Mark, I'm reluctant to ask! Mark proceeded to redesign the model so that it would have a built-up wing. This feature alone serves to save weight on gliders this large.

I've competed against the Jupiter Moon and lost. It's a very forgiving and competitive model. With the DT system, you can build one or two of them and have them available for the entire season.

The model is very simple to build. Choose stringy A-grain balsa for the fuselage and light-weight wood for everything else. Use aliphatic glue or epoxy to adhere the parts. The stabilizer shows dihedral, but this can be left out with no ill effects. Try to keep the weight of the model to 35 grams or less (mine weighs 29).

Finish the model with one or two coats of filler and two coals of nitrate dope. Cover the wing with tissue or plastic. Fly the model in a right launch, left glide mode. A bit of right bank on the launch will keep it from zeroing out and landing at your feet, Slight left stab tilt and a bit of left rudder tab should take care of the glide. Glide circles should be loose - no more than 100 feet in diameter, bui tightening up in thermals. Light the fuse every time and enjoy one of the true fun events in free flight."

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.
