after taking my phantom 2 apart and thoroughly blowing out everything and drying it i let it set a couple of more days and today i put it back together. it turns on and makes a weird beepity beep beep sound and the ride lights are alternating. they don't quite seems in sync i notice nor does the beeping stay quite in the same time. i hooked it up to the assistant software and it says it needs imi calibration but when i hit go it does not do anything. it does appear that the compass is ready in range and moves up in number when i lift the phantom. i am not absolutely sure i have the plugs in right on the imu but i am fairly sure. i think the gps is plugged into the right spot. it is in the large black plug on the main board near the battery. any ideas of how to proceed with troubleshooting? i am guessing i have a bad i.m.u.? thanks for all the help.
