Bipalo (oz2745)
About this Plan
Bipalo. Free flight biplane sports model. Model Aircraft February 1956. Bipalo 28in span F/F sport biplane.
Quote: "Attractive semi-scale model for point-five motors. Biplalo, by J Wood.
A BIPLANE makes a refreshing change from the usual run of monoplanes, and Eipalo was the result of seeing a friend's biplane put up art effective performance. It is strong, cheap, and easy to build, and in fact the prototype has been flying since early 1954.
Fuselage. Start by building two basic sides on the plan. When dry, separate with a razor blade, cut out all formers, and sew undercarriage parts to F2 and F3. Assemble fuselage sides on the latter and add engine bearers. Draw tail end together and add bottom fuselage spacers. Now add formers F4 - F8 and also the stringers on the top decking. Assemble F1 on the front of the engine bearers, and build up the cowl with soft 3/16 in sheet. One half is made removable for access to the engine. Add gussets, undercarriage, fairing, wheels, etc.
Wings. Lay LE and TE over plan, not forgetting to pack up the TE to conform with the rib contours. Add 1/8 in sheet tip pieces and all ribs, except those occurring at the dihedral joints. When dry, pack up tips, add ribs at dihedral joints, and cement securely. Remove from plan, and add spar and ply dihedral brace. Repeat for the other wing. Finish off the wings by making the struts, and fixing the tubas to the anchor struts. The model can be flown quite safely without the struts, as they do not hold the wings together.
Tail Unit. Lay the tailplane LE and TE over the plan, together with ribs and spar. Cement in all ribs. The fin is built over the plan in the usual manner...."

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.
