About this Plan

Ionosphere. Free flight sport tailless power model.

Quote: "For the experimenters, here is a lively little flying wing sports model, suitable for any of the half-cc motors. Ionosphere, by FWO Fisher.

THE Ionosphere 8D was designed as a robust sport machine for any of the popular 1/2 cc diesels, and will be found to give a stable flight pattern, even in the strongest wind.

Wing Panels. Pin the 3/8 x 1/4 mainspar and the 1 x 1/4 notched trailing edge over the plan, then cement the wing ribs in place over them, care being taken to ensure that the notches for the spars have been cut with slanting sides, as on the plan. Before cementing the ribs the root and tip ribs must be canted slightly towards the wing tips to allow for the dihedral incorporated. The 1/4 x 1/4 leading edge and 1/8 x 1/8 top spars are now added.

The wing panel is now removed from the plan and the plywood dihedral brace added, after which the wing panels are cemented together. The tip dihedral of 3/4 in should be carefully checked. The centre section is 1/16 sheet covered, which is inset into the top spars and trailing edge. The whole assembly is now covered and doped.

Fuselage. The sides are cut from hard sheet and joined together over the plan with the bulkheads A, B, C, D, E. The top is 1/16 sheet covered and the fin added. The 3/8 in hardwood engine bearers are drilled, and trimmed so as to give about 3 deg. downthrust. The engine is now bolted in position with 8 B.A. bolts, and the cantilever undercart bound in position with carpet thread and cemented..."

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.
