Ok... Good thing it's Friday because I'm ready for beer! I started removing the motors to install a set of TBS 900's and as I was doing so I tested continuity again and guess what... Nothing. Figured maybe I did have a screw touching that I couldn't see so I reinstalled the motors this time with the problem motor (#1) on arm #2. Tightened everything down and still not positive continuity. Went to test fly and no change... Still wobbling. Came back in and changed motors. Right after I got back in I grabbed the multimeter again and now was testing positive again. Put the TBS motors on and went to test fly. Same damn issue, wobbling with rudder/yaw. Also, theses known good motors also tested positive for continuity after flying. I'm going to put the TBS esc's on tomorrow and see what happens. If wobble goes away I'm going to have a conversation with Castle on Monday. If that doesn't fix it the only thing left I can think of is the Naza unit. I'll report back! Thanks for all the input.
