Hello my Phantom 4 also shakes when I fly in a straight line forward, sometimes aggressively, after the update. The update process was perfect. All calibrations were done. Everything else on the phantom works great except for this shaking sometimes. When I fly slowly in P, S, A or in Tripod mode its fine but as soon as I fly a little bit faster it starts shaking. I put on new propellers and the mounting plates were fine. There must be something with the output of the motors after the update, also note when you start the Drone it runs slower as before the update. Hope it can be fix soon because it is dangerous to fly like this.
That pretty much sums up the situation with my own drone as detailed in the actual firmware update thread.
I successfully updated the RC with the DJi Go4 app, then the drone using the latest DJI Assistant. I then updated each battery using DJI Assistant.
I have calibrated the IMU, compass and VPS and all are OK according to the DJI Go4 app.
Like others, the first thing I noticed is that idling seemed to be a little slower and quieter (that was a good change).
When moving forward or backward, though, the drone became extremely unstable, tilting violently backwards and forwards. I could hear the motors rapidly changing speed in a very aggressive manner. At one stage, I thought it was going to invert.
It occurs at any time when moving forward and, to a lesser extent when hovering with even the slightest of breezes. At times, it tilts violently backwards and forwards at an angle which must be approaching 45 degrees, even without making any changes to the RC controls.
I have flown this P4 and my previous P3A for hundreds of flights so I'm very familiar with what is normal.
The violent wobbling after this latest firmware update makes it virtually unusable. |
