Thanks so far….
So, here is the design…I can’t just use a normal airplane. Using the combination of our F1J and F1C stuff, I need to do something tricker.
The wing is a six panel, with a 12″ center section, 15″ mid panels, and 3″ tips. The center is flat, the mid panels have about 1″ of dihedral, and the tips have about 2- 2 1/2″. It will have a built up main spar- 3/32″ spruce top and bottom with a 3/32″ web. The ribs will butt up to the spar- Quite strong. The section is flat bottomed with a 7% section- Pretty thin, so will need a good spar and pretty radical geodetic structure.
The stab has 1 1/2″ of dihedral and is about 20% or so. The fin is mounted under the stab. This is very close to what Dickl Mathias and the folders are using- I like the looks!
The fuselage will either be a carbon tube or a rolled balsa tube. The pylon will be medium height. The bladder will be internal. The timer will be a Texas Timer with DT. And, there will be NO auto surfaces! I cannot believe I am saying that…I haven’t done a locked down model in years. Will see if I know how to trim without it….Should be interesting…
So, it is a change from the norm, but that is what I like- I don’t think I could build a standard model after flying all the trick stuff for so many years…If this works, I may make another with all the tricks for the other 1/2A class. Then I may feel at home….
