Help Needed: Air65 Battery Connection Issues

Hello peoples. I am in a predicament. My new air65 is having problems. I have to set the wire for the battery perfectly or the lights and receiver won’t work. It still does the little jingle at the beginning but if it doesn’t show the lights it doesn’t bind or work. What I have found is I have to get the wires perfectly placed away from the area they pinch to get it to work. Is there anyway to fix that? Problem number two is when I fly (I just bought the fat shark echos) I lose my display sometimes and them I loose video feed for a second. It all goes black kinda like it flickers and then I get video back and sometimes I don’t get my display numbers back. What’s going on and is it fixable. All the plugs and stuff on the drone are good except for one of the motors that has like a copper tint on the soldering which I hope isn’t anything bad but I don’t think that would affect the camera. ( I fly in my house btw) later I will try outside and see if I have that same problem.
