one way to make a chase or follow cam for paragliding with a gimbal

I used the g4 gimbal from: www.feiyu-tech.com plus an optional cable to charge the camera trough the gimbal via an external 4 A/h 2S Lipo battery pack. With this set up you can fly up to 5 hours with the go pro 4 black (it needs a lot of energy). A remote is being used to start/stop the camera or change settings. You can use the go pro app to have a pre view when flying - that works really well with the latest version of the app! It is important to attach the arrow on two points, as you can see in the footage, otherwise you will have vibrations on the roll axis. It needs to be balenced from the top to the end. The wind sack is needed to keep the distance harmonies - one can evan fly reasonably high wing overs with the right sice. The external battery pack should be mounted on the string that is being attached to the glider close to where the wind sack is attached. This way the wait of the battery is smoothing out the movements being created by the wind sack.
You need to drill two holes into the gimbal in order to get the cables in. Minus pole is at the end. You don´t need to do this, but the time u gonna be able to film is being limited to the battery life of the camera and that is not long at all with the wifi being turned on.

Camera setting: I found the 2.7k 4:3 setting being the most efficient, one can choose the crop in the edit later (move up and down) + keep the go pro battery in the camera when u charge it through the gimbal, otherwise it will be unreliable.
Start: It helps if the person helping you to take off understands the process off taking off, otherwise you will see is crash!!!
Landing: With the right length off the line you should be able to catch the arrow in most cases.
Gimbal setting: There are three speed settings on it, fast creates to much unneeded movements, medium I found to work, the best.

Would be really happy to see footage/improvements from other versions!
