I pay for it and find it useful, I've used it twice.
1. I was flying and some birds came to attack my drone and this was within the first two weeks of having it and so I decided to bring it in quickly, the thing I didn't realise was when the drone is facing you the controls are opposite, so while I'm afraid that the birds are going to crash my drone, I bring it in and flying forward and sideways I see that it is going to hit the clothes line so I fly sideways the other way and crash! I hit the tree on the other side(only 2 metres from the ground when it crashed but the gimbal had the gimbal stuck error code. So that was the first time I crashed my drone.
2. The next time I crashed.my drone was when 8 was flying fpv mode gimbal, and when I came to stop flying the drone didn't brake properly and kept drifting when I let the control sticks off, so I hit a bush and crashed and decided if the drone is not going to stop when it should then I should get it replaced.
