WK-M and Naza Truly Weird Problem

[Search49]

I have two units that use two different flight Control Systems. My DJI F550 uses the WK-M and my TBS uses the Naza. The Naza flys fairly well, and thd F550 is still in the tuning stages. But I've noticed a problem with both units. They both start out flying proper like. However after a few mintues they will go crazy. They will wobble, and spin and it appears they lose power. I haven't crashed as of yet, they both have landed rather rough, but stay on their skids. I have re-done the compass, checked and checked everything I could think of. I have every moved to a location about 4 miles away. I first thought it was because of the metal in the area, ie Lamp poles, Mesh fencing etc....., (First location is a baseball field, second is a open field with some power lines in the area and a billboard sign) Any one have any suggestions?

Thanks

ok, see how you got wires touching the cases that hold your gyros? =bad

take and reroute, redo whatever you gotta do to make them not touch and try again. the next step would be to hear the onboard video from each and make sure you can hear all 4 or 6 motors......
