Hi, Recently had a crash with the FC40. Wasn't too bad but it wasn't flying. Opened it up to find that the power cable had came separated from the motherboard. I had to unplug one of the wires from the naza controll board that was attached to the top of the drone so I had more room. Superglued the power cable back in and plugged the wire back into the motherboard and I was stoked to find it worked! I have flown it and it seems to work fine but it only blinks red...green right at the start then only red..I think it's red although in discussing there may be a little yellow tinge to it...so not sure if it is yellow or red..actually maybe orange. I'm in Austria so maybe a GPS problem but we have wifi and it's a popular place, so it should have gps. I flew it and it seems to fly fine, but when switching the S1 to return home, it just immediately descends to land. Any thoughts or advice on this? Luckily it works well enough to use for my purposes but I'm very afraid to fly it at any great distance where I loose orientation. I have it modified to fly a go pro so no FPV. Just thought I'd ask to see if maybe something I could check. Thought that maybe I might have plugged the motherboard wire into the wrong port possibly?....batteries are all charged. Oh and I try to calibrate by switching the S1/S2 switches up and down rapidly 10+ times and nothing happens. I've calibrated before, so it seems it is not reading this calibration command...but again, seems to fly as usual.
