Better late then never. On the Husban, sometimes it is needed to run throttle to full then back to zero, you will hear a beep, move the left stick down and far left, and move the right stick down and far right (Basically down and away from each other) You should hear a beep or two the lights will flash then go solid, at that point you should be able to fly. If that fails you can try to move the sticks down and out again. I have found after a hard crash you may have to do this two or three times. I will also add during this process you want the quad very very level. The 6 axis is sensitive and even 2-3 degrees off level will cause the quad to drift in hover.
