So i have had my 3dr Apm 2.6 up and running nicely on my tricopter and everything was working fine (rtl,loiter,arco,everything) and i pulled all my electronics, from that frame and put them on another 3d printed frame. Armed it to check motor dir. and after a few times arming it, it stopped arming. So i took it and plugged it in to my PC and it would not find the board, even under Device Manager i couldn't find it. Tried uninstalling and reinstalling drivers and mission planner, tried a different computer and a ton of different usb cables and ports. Also tried 3d radios and still nothing. So my question is do all $160 boards last 3 months?
