Thanks for the awesome work!!
I had a minor problem during my first flight. The PLA in two legs separated near the flight controller. This was likely a problem with my print settings, but I have an idea to improve the strength of the frame greatly.
Instead of pressing brass inserts into the legs, I've run a 1/8" (3.2 mm) drill bit through the two long holes in the legs. An M3x0.5 50mm bolt fits between the top and the legs perfectly, with room for an M3 locking nut at the bottom.
I've kept pretty good notes on my build -- if anyone is interested in a detailed bill of materials, let me know and I'll post it.
