After selling my last build I needed another Twinkle. Thought I'd throw up a build log... depron's pretty fantastic for little seaplanes so many the techniques could be applied to other designs. Depron build goes a fair bit faster than the balsa build, so I'm hoping to have a flying plane in a week or so.

First step is to make the wing. Quite pleased with the technique as recommended... put the top and bottom sheets together, and hot glue along the edges. Doing a few inches at a time, while the glue is still hot, smooth the glue out with a metal edge. This will hinge the trailing and leading edges. Then after sliding in the spars, you have a fully formed wing... run some thin CA down the spars to glue them in and it's done. After the spars set, you can set up the dihedral with a jig piece and laying the wing flat on the board. In pretty quick fashion the wing is complete save the tip floats.
