Yeah, mine only takes a couple seconds to stop blinking; that's why I thought I might be disrupting the gyro initialization by jarring the copter while plugging in the batt, the thing would just stop wobbling by the time the light went solid.
Good to hear ya got it fixed, now I know what to look for if I got a board problem.
I'm almost ready to start hover'n round the yard with mine, just trying to nail down how long I've got to fly and get er on the ground before I lose control due to low batt. So far I'm figuring about 3 mins and 30 secs, on the standard batt.
