Sorry to here of your issues 53, that has not been my experience at all. I would not ever be without one now. Sounds like you just got a bad one which sucks. I'm sure they will make it right for you. By the way what are you powering it up with. I have an old 6v nicad I use. I have to date used it on about 10 different models and each has worked perfect. The fact that there was little to no elevator trim needed proves its accuracy, provided you measure correct.
