In this session, I finished the soldering and assembly of the FlyLEDs control board. The assembly instructions supplied with this kit was also pretty easy to follow with no major issues.
After I completed the control board assembly, I did a quick test of the 4 wingtip light boards and 2 landing light boards by supplying 12 VDC to the power connectors on each of those. Fortunately, all 6 of those boards passed with blindingly bright lights.
Next, I printed and cut out the wingtip cutout templates from their website, and traced the shapes out onto the fiberglass wingtips. An oscillating cuting tool made cutting out those wingtip areas quite easy, though I did need to refine the edges a little more with a hand file in order to get the wingtip light boards to actually fit.
What's next? Probably time to get back to the finishing the fuel tanks? I might also try 3d printing a case for the controller board using the STL files that are published on the FlyLEDs website.
