Ditto on the P4 RTK. Still using mine after several years and going strong. Eventually batteries will be difficult to obtain but that's not the case now nor in the foreseeable future. It's also a large beast compared to new mapping drones like the DJI Mavic 3E with RTK which are more readily...
When you say "I always have airplane mode turned on", what do you mean by airplane mode? I fly a Phantom 4 RTK and don't own an Air 3 or Mini 3 so am curious what options those newer aircraft have on them. Thanks.
Phantom 4 RTK user for about two and a half years. Mostly used for mapping of my stream channel and fishery enhancement projects. Not an intensive flyer but I do enjoy it.
