Hi, I have a P2 that I have recently had to some moderate repairs (replace main circuit board). After lots of trial and error I have manage to iron out several little kinks (reverse stick, gimbal H3-3D bricked). I bench tested the P2 and I was concerned about the left stick. If I place the left stick into its locked position the system would shut down the motors. This is different than the original setup. Originally I could lock the left stick into the down position, the craft would descend under control until I landed it. Originally I had to place the left stick in the locked position and then move both sticks toward the middle bottom to shut down the motors. After my repairs and ensuring all my upgrade are current, the motors will shut down when the left stick is held down, and it is not in the locked position. This is freaking me and do not want to fly until some can help me determine a solution. Please comment.
