Ok. After inserting the wire where you saidZ It snapped in easily. I took it outside, turned on, calibrated the compass and it all seemed fine. Unfortunately I wont be able to put the props on until Sunday and check if it is working.
There might be sand in one of the engines, should i take compressed air and shot it out?
If everything works fine (i did notice every second or two on my phone display when i tested it there was like this small little lag) should i keep flying? What would your advise be?
Those wires looked pretty chewed up. I would replace both the compass and antenna before flying. Why risk your bird for some relatively cheap parts that are critical to flight?
