Hope you have better luck than I did with mine. First half dozen flights were impressive, then tilt went to hell, oscillations.
Worked 2 weeks on it getting it all dialed back, only to have it happen again.
Did lots of research.
Found out it's an old first version Martinez board with real old, first version software that has been 'nulled', meaning you can not upgrade firmware.
So, I gave up on it. Ordered a new AlexMoss SimpleBGC board to replace it with.
Will be setting it back up tomorrow.
