First time drone builder

The AIO FC was great soldered up fine and was simple enough to program on betaflight. shipping was fast as well.

Good board

I actually killed mine with a tiny stray solder blob. Happymodel support is surprisingly good. The board itself is a decent board. Lower amp ceiling than I'd like, so I upsized to a 40A with a separate receiver. The motor pads on this board are quite hard to solder to.
