Hello, We had great early experiences with our P2V, but after six flights or so we are having a real problem with stability and control. We are concentrating our efforts on the compass calibration. After some conflicting info from the dealer, can someone please tell us what should the LED status be after the "Nose Down" step? We get a slow yellow flash indication. We have demagnetized the compass several times, and all the data on the Assistant is within spec, the the P2V has a mind of it's own when it flies, and is really unusable now. Thanks!
