[QUOTE="RotorWash, post: 102089, member: 18210"] Were you in Sport mode at the time and/or was it windy at 30m? Not that you would need to be to have it drop to ATTI but the Spark seems more susceptible to do so in those scenarios. For the first month I had my Spark I could get it to drop to ATTI pretty much at will by whipping it around in Sport mode. A third and very slow compass cal reduced the problem from 90% occurrence to around 5% for me. When the issue was prevalent ATTI was always preceded by yaw errors in the log. It's as though the onboard CPU couldn't handle the data fast enough if there was any "slippage" while in flight. Yet a compass cal did improve it by a lot so I dunno, maybe it's just super sensitive. Thought I'd mention this as other new pilots may run into the same issue. No doubt you're already aware and in your case it may have been some form of interference. I've got 730km on this bird and never had it drop GPS while in P-Mode and in the open and I've flown around all sorts of electrical fields and have had no issues in that regard but Murphy’s law is always applicable.
