Say you are flying your drone not too far away from your home and someone comes and insist they will do something bad to your drone when it lands because they are not particularly happy about it.
What you need, in that case, is a Litchi mission that automatically takes your drone to your backgarden and lands.
This is very easy to do in the mission hub: create waypoints navigating to your backgarden, you may also want to include few evasive manoeuvres to descise the location of your home. Then you need to finish the mission with landing the drone. This is done by going to mission settings and selecting land at the end of the mission.
I have tested mine this morning. The drone landed exactly on the spot and turned itself off!
So if someone approaches you in a confrontational manner about your drone, just start your escape mission and go home.
This feature is genius!
Disclaimer: if you are planning on doing a long range flight with your drone make sure you follow local regulations, such as CAA in the UK.
In this tutorial, I will use waypoint navigation in Litchi app together with its online mission hub for creating waypoint flights. I could, of course, create the whole flight in Litchi app but it’s much more convenient to do so on a PC using Litchi website https://flylitchi.com/hub.
Few things to bear in mind when planning such flight:
- Make sure it’s no longer than 15 minutes including the flight back, such that at the end of the flight you have at least 30% of battery available. This is in case you have a strong headwind.
- Use UAV Forecast website or their app to check for weather conditions, especially for the wind direction. You want to begin the flight into the wind so that on the way back you fly with the wind. Use many of the apps available for checking the wind direction in the area you want to fly (such as MyRadar, WINDY or tens of other similar apps).
- Litchi is capable of completing the mission even if there is no signal from your controller. However, there are some limitations such as it will fly at the last commanded speed and the gimbal pitch will no longer be pointing to the POI.
Registering with Litchi
If you haven’t already got an account with Litchi, go to https://flylitchi.com/hub and create a new account. By doing so all the missions you create on the website can be synced with the mobile app.

Return to Home
If you are finished flying and want the drone to land itself from where it took off, you need to activate the return to home function (RTH).
To activate the RTH, quickly toggle the S2 switch back and forth. The controller would then start beeping and the return to home procedure will be initiated.
To cancel RTH toggle the S1 switch back and forth and move the S2 switch to the uppermost position. The controller should then stop beeping and the drone will simply hover until you take over.

The outline of the CAA guidelines:
The regulations for recreational drone flights are contained within the Air Navigation Order 2016 (ANO) which is the primary document for all aviation regulations within the UK. In order to keep the regulations at a proportionate level for these small drones, a set of specific, simpler, regulations apply to aircraft that have a mass of 20kg or less (which are termed ‘small unmanned aircraft’ within the ANO).
In simple terms, these regulations state that:
- you are responsible for flying your drone in a safe manner
- you must keep the drone in your direct sight at all times while it is flying so that you can ensure that it does not collide with anything, especially other aircraft
- you must not endanger anyone, or anything with your drone, including any articles that you drop from it
- if your drone weighs more than 7kg, additional rules apply if you fly in certain types of airspace and you must not fly above 400ft above the surface
If your drone is fitted with a camera, there are also a number of additional limitations surrounding where you can fly it, and how close you can fly it to other uninvolved people or objects. In order to be able to fly within these areas, or closer than the minimum distances that are in the regulations, you must obtain prior permission from the CAA to do so.

Phantom 3 series drones use brushless motors for propulsion. At full speed with sharp blades, especially the carbon fibre ones, they have enough force to chop yours or somebody else’s finger off. If your drone hits someone it can seriously injure the person. Having the propeller guards should at the very least mitigate the injury caused.
Safety issues aside, they could stop you from crashing and destroying your drone. Say your drone touches a wall. Now those high RPM propellers would break to pieces sending your drone to the ground. If it was high enough chances are you would need to get a new one or at the very least spend hundreds of £ replacing the gimbal, camera and possibly the shell.
With the guards attached it would simply bounce off and carry on flying.
I understand that the guards add to the total weight of the drone and mess a little with the airflow, shaving off valuable 10-30 seconds of the flight time. Now imagine what you could have done with all that time? Personally, I have never used more than 75% of the battery.
There are two types of guards available: permanent ones and detachable ones. There almost zero difference between the two and the obvious choice is to go for detachable ones.
They cost few quid and take about 10 minutes to install, only because you have to deal with 16 screws.
My personal view is that DJI should have included that accessory by default. I see no reason why you shouldn’t install them on your drone as they don’t affect the flying characteristics of the drone and encourage everyone to do so. I have mine the same as in the picture above, they are nothing special but they do the job.
