I had an issue I posted elsewhere with Autoflight Autopilot's Follow Me mode overshooting and oscillating when I stop:
I suspected it was a software issue and contacted support (Autoflight, not DJI). They said it may be because my iPhone 5S doesn't have good enough performance for Autopilot...
If you're still looking, this is under "Advanced Settings" within "MC Settings". This and switching to "Hover" on signal loss should solve many but not all Phantom-trying-to-crash-itself problems.
Cool, this is the first thing I've found about upping the max speed in P modes... what would you get without a tailwind? 30 mph? (Still thinking about upgrading to the 4 but not happy about the drop in speed for sensors I don't need)
Did anyone ever figure this out? I have a Phantom 3 and Android and the same problem, no data with WiFi connection to Phantom- and Android won't let us leave those values blank...
