It is nice the 7th channel works with the update for the P2V, but not as I would have hoped it would. This is what I have found by installing the potentiometer on the controller. As always, YIMV(your installation may vary). First I had a 5K pot on mine. To get the camera to move up or down was only about a 3 degree movement of the control knob. Very delicate. So the next one was a 500 ohm pot. That spread the movement out to about 90 degrees of rotation. So I tried a 100 ohm pot. That moved the adjustment out to around 110 degrees of rotation. But, and a big BUT, it is not a smooth movement from up to down. If camera is up and I start to slowly move the knob, nothing happens. Then all of a sudden the camera starts to move and continues to move all the way down. The only way to stop it from moving is to rotate the knob in the other direction a very large amount of rotation. You get to a spot where the camera will stop dropping. Same operation when moving from all the way down to up. It is almost as there is no command to the gimbal until a certain point on the pot and then the "move" command is given. It acts just as if you had your quad in atti mode. It, the camera, just keeps moving. You have to give it the "up" command to get it to stop moving. This operation makes the exact position of the camera difficult. It is better than having to reach, in my case, deep into the box I use to block the sunlight on my display. It just would be "nice" if the camera would only move when you turned the knob on the potentiometer. I have tried almost every possible setting with the quad connected to the laptop without any improvement.
