Bought one, - 210 non RTK with the Z30 and XT and Cadence. Nothing worked properly, 210, display, Z30, controller, dealer said software issues, DJI may fix within 6 weeks, sent it back got a refund. I think its someone else's turn to waste 2 weeks trying unsuccessfully to make things work. Fantastic dealer, great potential aircraft, shame it didn't work as it should but lucky I got it back after the flyaways. RTH didn't function. At all. In any shape or form. And I'm not the only one.... Be a beta tester, you learn lots about controlling panic attacks.
