In the picture above, there is a grey wire routed over one of the GPS antenna leads on my P2V+ V3.
It goes from the GPS module itself to the PCB. I'm not going to dismount the PCB to find out exactly what this wire does. I suspect it provides power of some sort in addition to the other two wires attached in the same fashion.
Wire insulation on metal is something we in aviation would fix and/or repair IMMEDIATELY. Then, install such devices as to prevent chaffing in the future. Things like this have brought down aircraft throughout our history of flight. Simple, small things that had the engineers of been paying attention to could have saved lives. In this case, drones. The vibrations from rotary wing aircraft are pretty severe, much more so than fixed wing aircraft. Just the nature of the beast. While this drone isn't capable of variable pitch blades, it depends on motor speed to produce lift instead of a continuous engine speed and variable pitch, the vibrations experienced in flight are almost as severe as a variable pitch aircraft.
I wonder if this isn't a contributing factor to some of the true flyaways recorded by various DJI/other drone/aircraft owners. Wire against wire isn't something I'm terribly concerned with. However, wire against a hard surface IS something I will remedy before the cover goes back on and the next flight. It is critical that any solution one uses is nonconducting. So cloth tape or foam strips are what I'm left with at first glance. Some of the internal IMU wires are laid right up against the IMU module itself. Not good. Not at all. Other wires lay right up against the PCB. Again, NOT good at all.
I've also noted some other wires against hard surfaces. I'm going to leave the cover off and get myself some foam strips and cut them to size to place in-between the multiple areas I've identified. Cloth tape has a way of coming off in high heat areas.
This isn't acceptable out of a $1200 setup. The drone, two batteries and a nice case. If the drone is damaged, nothing else is worth much when I compare the drone to the articles that came with it.
