Had the same problem and the solution was STUPID!!! I use a JR 9303 with Spektrum 8 channel RX. Everything was set up correctly and showed that all controls were moving in the proper direction in assistant, however, just by chance I noticed that if I applied ANY downward pressure on the throttle it moved it into failsafe. I disconnected the USB, moved my right stick bottom left, then with my throttle stick set at zero throttle I moved it to the right trying not to pull down on it at all. BINGO! Motors armed and everything worked perfect. I played with some trims and it still did it, not sure why, and I couldn't get away from it happening. It took me several arming sequences to learn to gently push the throttle stick to the corner without pushing it down. Hope this works for you.
