Hi. I began building my quad from scratch, learning along the way. 2 years ago, after it's first flight, and crash, I set it aside, until now. I seem to have forgotten some of the info I had gathered previosly, such as which model of controller I am using, and which version of Simon K software to upload. It may be a KK 2.1 board? It has no programmable panel.
Attached is a photo of the board (it is wired in place, and has the USBasp header attached).
It controlls 4 motors in X config via the 4 simon K ESC's. The system connects to the RC and the motors spin up to full speed, tho there is no directional control.
If anyone can shed some info on this, I be most grateful.
