Sorry, I thought this might warrant its own thread. First, let me say I have NEVER experienced this problem before 3.06, and I now know its not a 1 time fluke. When I go to do my field compass calibration, I get 1 green light and then 2 flashing red lights. I looked for the pattern on my stickers on the controller but couldn't find out what they mean. Its taking me about 5 tries or more to get it flashing green. And, I'm not sure if its a problem or my imagination, but I was flying pretty far out and went to use my home lock and it appeared to me to go off about 90 degress from where it should have. I switched off home lock and proceeded to use the radar to get the aircraft back home to me. Landed, changed batteries, (tried another calibration, same problem), and this time it flew fine, home lock and fail safe worked as they should. Can someone tell me what 1 green and 2 red flashes are and if anyone else has had this problem when field calibrating the compass. As I said, it all started after 3.06 was installed. Many thanks. J.
