I have had my mantis q for a little over 1 week now. Everything was great until yesterday. I went to fly in my yard like I have been doing for the last week and I got a audio message on my phone, warning compass calibration lost due to high magnetic field please move and recalibrate. So I landed and went to a wide open soccer field and recalibrated compass, all went well so I took off and flew it for a couple mins. I took the drone up to 400 feet, flew around for 5-6 mins and then it came with the same warning. Any suggestions? Or just return for money back?
