Some things I've learned from using Litchi waypoints for 20+ missions, down rivers, over lakes, around schools and parks etc:
- Always check (and recheck) your altitudes of each waypoint
- If you're crossing something (anything), make sure your altitude changes to clear that obstacle
- Place a waypoint before an obstacle to get to a clear altitude, Litchi gradually changes altitude.
- Always check your cruising speed
- Don't be afraid of using a bunch of waypoints to get your camera into position.
- Be wary of putting POI's, in succession, on opposite sides of the compass, you'll get crazy swings.
- Revise your gimbal speed settings to get smoother changes of angles (look them up on youtube, I forget what I have)
- Revise your mavic turning and speed settings to get smoother changes of angles (look them up on youtube, I forget what I have)
- Always check which POI's you're pointing at
- Always check to make sure "POI" button is selected at every waypoint, if you're using them.
- You lose "actions" at each waypoint with curved lines (except I do get "start recording", but only that one), but curves makes video so much smoother.
- I don't think you have obstacle avoidance when running a mission, but I have gotten warnings when I faced the sun on a mission.
- Make your first waypoint directly above your home point. Especially if your 2nd waypoint is behind an obstacle.
- Make your last waypoint directly above your home point. If you lose contact, Litchi will finish the mission, right above you.
- Remember the altitudes are referenced from your take off point. So if you have the altitude at 150 feet, that is 150' above the take off point. Mind where your take off point is in relation to the surrounding terrain.
- If you think you're far enough away from a waypoint to get good video of it, you're probably not. Back up some more.
- ALWAYS ALWAYS make sure you set your RTH altitude much much higher than any obstacle it would fly over to come back home.
This was my first real mission around our local high school. Flew there (probably a mile from my house), then started the recording...it's pretty dark, I was still new
