yes, the wires are your antennas for the drone. They are important..... however when you buy a new set of landing gear they come with the new wires. You have to disconnect the gimbal from the drone and there are 4 wires attached with little gold connectors. They need to be disconnected, then they should be able to be pulled through the landing gear mounts. However, if you want to do it the easy way. order new landing gear, keep it just in case of another crash, and then just use the doors that came with it. LOL. I hope this helps. I have had the drone completely torn down all the way to the core. I had to replace the body.
As a side note, I think i figured a fix for my problem, except I was trying it today, dropped the camera with the cable attached, and I tore the cable. I am so mad at myself.
