The real advantage of waypoints are:
- to get close to tragets farer away instead of being 100m over them because you are afraid hitting something when flying manual
- to follow fast targets on known paths like cars, trains where you dont have time to correct heading
- get really smooth!! circles you dont get with manual yaw stick
However most of this you cannot do with DJI GO app.
1. the 500m radius is rediculous, try to follow a train with this or even a bicycle
2. flying the mission before - forget it you will probably loose connection behind a tree or not be able so see how near you are over trees ----> you will stay much too far away of everything because on the tablet you cannot estimate the distance and with the eye - ever estimated correctly the distance of the trees behind?
3. I think there is a additional speed limit also in DJI GO for waypoints?
I understand why DJI did this with their P3S now in kiddies pricerange as everyone can afford a drone now but most are too stupid for it, there will be casualties soon. Unfortunately Inspire Pilots do suffer under kiddies restrictions as DJI does not spilt the Firmware/Software.
We pay enough so they should do so!
So how to make safe waypoints?
Waypoint planning over far distance is a lot of preparation. You have to know real ground altitude and hight of trees or buildings in the area.
Lets say your starting point is in 510m alt. On your path the terrain will go up to 560m in 1000m distance. There are up to 30m high trees.
A safe waypoint must be at least set 85m at this point - in real it will be only 35m high just over the trees. You have to do this calculation for each waypoint! And you have to consider obstacles in the path. Its a lot of work but its possible and the only way to stay near a POI which you could not do manually from the same distance.
Also be aware of handytowers and research powerlines 100 KV+ in the area. You can find them here:

Also even if your last waypoint is far away set a back path anyway - it will return on this path even if there should be a connection lost and avoid less controlled failsafe mode (depending on FW and app). Like on the waypoint path you can adjust speed and always know where it goes, while in RTH mode you have to wait some time to be sure it points in your direction, depending on rth alt this can take some time and you never know sure. In the worst case you think to get it home faster but actually drive it more far away.
