Hello my name is shamarr. Recently ive noticed that my typhoon H has been drifting alittle to the right. Having this same H brought to yuneec for a fly away i begine to have flashbacks of such a dreadful day. Anywho i did countless calibrations and nothing worked. Finally it hit me and i checked the st16 and noticed that my right stick caused the drone to tilt 25% to the right (j4). So i looked on here and saw the recommended video,watched it, and attempted it and the j4 will not clear the calibration test. All the others are green yet j4 is stubborn. What should i do? I dont want to take it to yuneec and possibly deal with a fee to fix it. I tought about taking the st16 apart and trying to locate the issue myself. The st16 has been sitting all winter. I brought it out today and this bug shows up. Thanks for any help gievn in the near future.
