My previous post showed a damaged 5ghz antenna cable In the controller. The bird was flying good, stable just distance was reduced, I was unable to get further then 700ft without issues, even in clear fields. I had a cable given to me and removed the damaged one and installed the new one without success, the bird was unstable always drifting and moving up and down In elevation by itself. I was also getting a compass error all of a sudden. Now, I scrapped the patch antennas and upgraded to a DBS, which I installed without issues. The bird still drifts. It's not stable. I've tried multiple IMU calibration in clear areas, calibrated the compass numerous times and recalibrate And also relinked the controller. Nothing has worked. I don't know what to do. ???? The mod # in the IMU section keeps jumping around even when the bird is stationary on a flat surface, I'm not sure if this is normal, never checked before. The number is anywhere from 1540-1570, which from what I've gathered is correct. Any help would be appreciated. Is it the remote? Is it the compass? I'm stumped. This is not my video, but this is exactly what my phantom is doing, keep in mind is was flying perfectly fine before.
