New here, and new to the Karma. Been flying a DJI for quite some time so not new to the drone world. Recently picked up the Hero7 black and I wanted the Karma grip for it. Ran across the refurbished deal that cost the same as the Karma grip so that was a no brainer. Anyway...yesterday the Karma showed up. I charged it all up, performed all updates and got myself familiar with both the drone and grip. Went outside to calibrate...fail. Tried over and over...fail. Always on step 2. I get full blue circles on both steps but calibration fails EVER. SINGLE. TIME. just when it gets to the end of step 2. I've tried everything. Restarted both units countless times. Moved to a dirt road in the country in the middle of nowhere a half mile away from any power line or anything. Walked 100 yds from my truck, left my phone and watch in the truck. Walked away from the controller etc... I've literally tried everything. What a bummer. Thinking I need to send this heap back? Any suggestions?
