I purchased my Q500 from a private owner in Livermore California. Which is in the Northern part of California. I live in the central part of Calif. around Bakersfield. I powered up my Q for its first flight and all light indicators gave me the okay to fly. I have not done a compass check yet and have to this writing no problems.The 1 thing I do try and do is start in true North. The reason for this post is all the back and forth about the Typhoon compass calibration.Now on my xk 380 I always do the dance prior to every flight. I think it is just a confidence thing.
