You wouldn’t expect a model with this name to be a serious aerobatic airplane, would you. It rather implies some nostalgic feelings; a longing for happy days when you didn’t have to have the latest technology, the most powerful engine, the lightest balsa wood, and the best airplane design. The design of Boogie Woogie concentrates on looks and fun.
I should make sure that I don’t belong to the oldtimers brigade. I cannot see much sense in building an old design just because it is old. Instead I can be inspired by a beautiful shape and a certain type of building technology. You just cannot deny that the look of an old Tutor house, a “naked bike” type motorcycle, or the “stick and tissue” look of model construction has it’s very own kind of beauty. The “technology made visible” appearance has its special appeal. That’s how Boogie Woogie came to life.
It had to be a biplane, had to have the stick and tissue look, and should be able to fly all the round manoeuvres. Flaps were planned for the bottom wing only with the ulterior motive to add some lift should that be necessary. Right from the beginning there was no intent to achieve square manoeuvre performance. The whole configuration doesn’t lend to this goal, and I honestly doubt if a perfect Square Eight would look nice with this airplane.
Building this model is not very difficult. Only fuselage construction is a little more time consuming than the ordinary sheet sides method. Both wings have the same planform. For the bottom wing one half of the ribs are cut shorter to allow for the flaps. The front part of the fuselage side is balsa sheet with the stringers glued into them. Ply doublers, vertical and diagonal stringers are added later. Please note how the edges of the sheets between the stringers are carefully cut and filed to a lovely round shape. This adds tremendously to the looks of the airplane and should never be neglected. Actually I have regretted later that I didn’t do it in other places ( like in the fin and the tailplane ). An RC plastic engine mount was used to be able to exchange engines easily. The second former is tilted to give the exact undercarriage location. The bell crank is mounted on a ply plate at the same height as the tank floor, thus supporting the former. Small cutouts in the fuselage sides are needed for full deflection of the bell crank. The centre wing struts were installed by using short pieces of trailing edge stock, glued to the fuselage sides as well as to the centre ribs of the top wing ( these are spaced at the correct distance). That way I got the exact “outward” angle of the struts - so important for the biplane look - and it made installation very easy.
Of course this airplane HAD to be covered in yellow tissue. Yellow silk is even better, however I find it a nightmare to use. If yellow silk is not found it can easily be coloured with dye. As expected Boogie Woogie did all round manoeuvres, with the Vertical Eight maybe not quite below 90 degrees. With a sharp eye Squares are just visible but not pleasant to watch. There are better models for this task.
The wing span of this airplane is 102 cm. It was flown with an Enya 45 on 17,50 m lines. Don‘t ask me about aspect ratio, wing loading, tail volume, and Cm + Lt % < Ld x a CG > M/ @ W *FÆ - mv ( ½ Ca / r ) A* § ! ? !! or similar important values. These were not built into this design.
