@Dbez1 Litchi is awesome, been using it going back to the
Phantom 4. Only issue is DJI's withdrawal of support for autonomous execution in third-party apps like Litchi, ending with the
Mavic 2.
The 'Virtual Stick" operation that DJI has made available on some DJI drones since the M2 leaves much to be desired, and for most post-M2 drones the app is the new, under-development Litchi Pilot, not Litchi, the former having bugs and being very feature-limited compared to Litchi.
For these reasons if you go the Litchi route to get your waypoint legs, I'd strongly recommend picking up a used older drone that supports Litchi and on-board waypoints, like the
M2P or
M2Z. The first Mavic Air, and Mavic Pro, as well as the Phantoms all work with Litchi.
If you want to use a more recent drone like the Minis,
Air 2(S),
Mavic 3 (non-enterprise) you're looking at Virtual Stick operation, and the limited Litchi Pilot app. I can't recommend this solution at this point.
Rather, for a more modern drone I'd recommend the
Mini 4 Pro,
Air 3, or
Mavic 3 and use the DJI waypoint functionality integrated in DJI Fly. It's based on the same on-board, autonomous execution that works with Litchi on older drones.
