About this Plan

Justin. A/1 glider design.

Quote: "A glider designed to the international A/1 formula, by B.R. GLENNY.

THIS easily built A/1i is the developed version of a basic design which has been successfully placing in New Zealand contests for over four years. It is ideal as a club 'one design' contest project, being quickly put together, very economical in materials and presenting no difficult trimming problems.

Wing. Begin the construction by pinning down the LE and TE of the wing on to the plan. Do not forget the packing under the front of the TE. After cementing the ribs into position the main spar can be fitted. Now finally, before removing the structure from the plan, cement the diagonals of 1/16 sq in place.

Fuselage. First cut both sides out of 1/16 in sheet. Now pin one side down on the plan and cement the longerons and diagonals in place. After this cement the other side in position and remove from the plan. Finally cement the wing and tailmount; rudder, etc., in position. The rail construction is self-explanatory.

Covering. Cover the whole model with light weight Modeispan, water shrink and apply two coats of dope.

Trimming. I trim all my Nordics for a fairly tight right hand turn. The best tow hook position for this model was found to be 1/4 in in front of the CG."

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.
