I am considering an S900 / A2 / GH4 but I have concerns about the A2's reliability and stability. I am curious to hear the experiences of P2 users who now have an S900 / A2. The P2 has some reliability issues with batteries and we had the horribly annoying compass declination J hook which is now thankfully fixed. Losing a P2 to a duff battery would be bad enough, but losing an S900 would be intolerable. I want to be 99.99% certain it's going to stay in controlled flight. I am also curious to know if the A2 auto-declinates. Do you rotate the puck? And if so, does it fly arrow straight in high-declination areas or does it hook? Anyone have some GPS plots of an A2 in a high declination area (+/- 12 or higher). With that much money in the air, it had better be rock steady and straight as an arrow! I also read about the GPS dropouts and I am curious to know what may be the cause. They could be isolated one offs (bad hardware, install issue) or it could be a common hardware GPS reset causing a cold start. GPS issues would be a deal breaker even if infrequent. And why is the A2 banned by the CAA? Ignorance or is there something to it?
