Hello all I purchased my P2V+ in Hong Kong and have been flying around the world with it for 2 months. No issues whatsoever in Fiji, Hong Kong, Indonesia, Thailand. Sample footage here: https://www.youtube.com/watch?v=4B1YPD5b5lk However, I brought it with me to my home country of Canada (Quebec area) and the unit compass calibration got so out of whack that it decided to go for a dive in the ocean. It's now gone and I have lost $1500. I would need your help in understanding what happened as I've been flying this thing for months without any issues and pondering the option of buying another unit. Here are a few more details. - Initial takeoff was followed by a circling that got bigger and bigger (and faster) unless I intervened to stabilise the unit. - After about 10 flights, the P2V software detects a compass calibration issue and requires an advanced calibration. - I complete the advanced calibration (all confirmed in the software) and take the baby out for a test flight. Same issue occurs, but with less magnitude. - I take it to the ocean front and take off with no issues. Stable for first 2-3 minutes (altitude about 100 feet) and then enters a high speed 45 degree dive straight into the water. I try to recover by sending the unit straight up but with zero response from the Phantom. On the bright side, no one was injured (this has always been my worst fear), but at the same time, I don't believe I made a piloting error. I am seeking for your opinion on what could have potentially happened. Was this an engine failure, compass issue, or something else?
