I was shooting from a moving boat. Seems that as I moved, I went beyond the range based on the home point and the drone just hovered until we went back near the drone. I haven't had that problem in the past, what happened? I ran through all the settings and couldn't find anything obvious. I have max range set to on. What am I missing?
Did your Phantom lose signal and hover because you had set Hover as the Loss of Signal action?
One thing you also need to be aware of if flying from a moving boat is Low Battery RTH.
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect the safe return of the aircraft.
Users are advised to return home or land the aircraft immediately when prompted.
The DJI GO app will display a notice when a low battery warning is triggered.
The aircraft will automatically return to the Home Point if no action is taken after a ten-second countdown.
The user can cancel the RTH procedure by pressing the RTH button on the remote controller.
The thresholds for these warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point.
You don't want to be flying near your moving boat and have the Phantom wanting to go back because it thinks the battery level is just enough to go back where it started.
The way around that is to reset your home point during the flight so the Phantom knows it is not far from home.
You can reset home in the app and you get two options.
Reset home to the current location of the Phantom
Reset home to the current location of the controller (only if you have a GPS enabled phone or tablet).
Either should be fine to keep the home point nearby.
Reset a few times during the flight as you keep moving.
Here's where you reset the home point in DJI Go 4.
Your version may be different but it should be similar:
