Hoping someone can help me fix my silver umax. I decided to open it up and check out where the ground balance trim pot is and discovered that there was a loose wire in there. The white wire shown in the first picture, was connected to the sensitivity pot but not connected anywhere on the board. I looked around everywhere and found only one spot on the board that looked like a possible spot where a wire might have broken off so I soldered it back to that spot as shown in the second picture. Not so sure that was correct cause I did an air test with a dime and changing the sensitivity doesn't seen to make any difference at all. The dime hit at the same distance with the sens at 1 as it does maxed out. Can anyone tell me if I got it right. Thanks
