My understanding of a Litchi Waypoint Mission:
You can make a mission with poi's and have the drone/camera automatically point towards this/these. Fine, thats one of the main features of Litchi.
Another main feature is it will complete your mission even if connection is lost! Behaviour if/when connection is lost can be configured in app.
You can even set custom heading or even initial heading for those spesial cases/shots.
Do we have more options?
Yes, you can set actions on waypoints!
Speed, gimbal pitch, take photo, start/stop movie etc..
Important notice about actions is if you set any speed change or gimbal pitch change on your waypoints, you need a solid RC-AC connection! I always plan missions with actions on wp's to be within range of RC.
When uploading you mission to your drone, it will not contain everything about your mission. Some stuff, like actions, is controlled by your app through RC-AC connection.
Same with speed, cruising speed is your initial/programmed mission speed.
It can be changed by your RC stick, and new mission speed will be set. If you have no speed set at your wp's, this will be your speed the rest of the mission.
Manual clearly state that if connection is lost, mission will be completed with the speed the drone had when connection was lost.
Okay, waypoints..
They can be curved or not.
Regardless, the drone will slow down.
Curved waypoints cannot have actions set, because drone clearly misses the actual waypoint. But thats wanted behaviour, right? ?
A curved waypoint, by default, is devided into 5 "invisible" wp's.
And that's the reason it slows down during the curved turn..
Most of my missions is done with curved turns, and if cruising speed is set to 30 kmh, it will do the curves in 15-20 kmh. This will also be the speed in the curves if my cruise speed is set to 50 kmh!
By now, you understand that you will not be able to do an orbit mission around that famous lighthouse in 50 kmh!
Still reading?
Do not expect obstacle avoidance to work during your missions. Always plan your missions like it isn't active!
Spark front sensor limit is 5 meters and speed must be max around 10 kmh..
Most missions will not point the front face of the drone in the flight heading direction.. that's why we make missions, right?
Fly safe and make your missions well cleared of any obstacles.. and ground!
