Hello from Newbiville. Actually I've been in RC for over 20 years but just got into drones recently. Purchased my first P2 used with an H3-3D that needs a little work. Will be doing the whole FPV OSD thing with it. My question is what is the purpose of the red/brown/yellow ribbon cable that runs halfway down one of the landing gear legs? When I first pulled the unit out of the box I was really miffed because it looked like it had be cut off. Then I realized it was made that way. Searched various sources for about the past hour and can't find an answer. Saw in one video where it was connected to a board but doesn't seem to be used for anything. This leads to my next question which is where do you find a good technical manual for the P2 that would show all the components, cables and whatnot? Haven't found that either. Thank you. Never mind. Found the answer while reading the user manual. Imagine that.
