Soldered the rear wing together today. This is actually not the smallest thing that I have soldered. When I was an engineer, I have to make prototype electromechanical gadgets. Some of the electronics components were surface mount. I actually had to do it under a microscope. Now, all I have is a pair of 3.0 reading glasses. I guess I'll have to buy a loupe eventually.
Also, as you can see in the photograph, I also engraved the resin body a bit to make the lines a bit deeper. After primer, paint and clear coat, I am sure whether the lines will still show.
