I already created a posting about this issue, but it was deleted for some reason. It was stated that it belonged in the sticky thread. It would have been great to be able to get a heads up before deleting. It took a while trying to type out and explain the issues I am having. Also, this thread doesn't seem like the correct place for this kind of posting. This thread was started in the beginning to address updating procedures and not a posting to where people that have updated the latest firmware can list some of the issues they have found with it. Hopefully someone can get a posting started to be able to address these issues with the new firmware. For now, I will try posting here and maybe try to find a way to remedy these issues.
First off, after installing the latest firmware I performed a gimbal calibration and once it had completed, the gimbal was turned about 20 degrees to the left. Before the update, I noticed that may video footage seemed to be turned slightly to the right, but I figured it was an illusion, due to the gimbal looking straight when I would look at the copter. After performing the calibration, I powered down the bird and then turned it back on. Once it had initialized, the gimbal was ever so slightly to the right. I tried the calibration again and it went back to being about 20 degrees to the left of center.
The second issue is much more serious.
I was getting video dropouts quite often. The copter was less than 100' from me, so I know it wasn't a range issue. Instead of dropping out and then picking back up a few seconds later like what generally happens when I get some distance between the bird and the ST16, the video would freeze for about 15-20 seconds and the video would zip back up to the current feed in quadruple time. I already explained this once, so hopefully I am able to explain it clearly again. Instead of freezing for a period of time and then jumping to the current position in an instant. The video feed would start playing again, but it would be behind and would replay everything that had been captured during those 15-20 seconds. However, it would be in almost like a triple-quadruple speed and then when it was back up to the current location, the video would smooth out again. I generally fly FPV, but it was so bad that I couldn't even think of flying via just the video feed. Also, the video feed was very rough. It would stutter at times. I checked the footage afterward and everything is fine. Hopefully, I have been able to explain my issue. I may try starting another posting again. We really need to get another sticky started where members can post their experiences with the new firmware. Positive or negative. I am going to copy this posting in case it gets deleted again.
UPDATE:
I also found out that when I flip the gimbal pan switch to the 1st position, it does not bring the camera back to center. It just sits at whatever position it was previously panned to. However, there is a very slight panning that take place when it is sitting. Very slowly turning. When I flip the switch to the 2nd & 3rd positions, I can pan with the know. However, it won't swing back to front and center when flipped all the way up.
I have experienced the same issue after installing v3 firmware. I noticed that the gimbal (after recallibrating) was moving slightly toward the left (I think a full 360 turn of the gimball would take about 1 minute). I could pan and rotate the gimball with the ST16. Panaroma function took 18 photo's without turning the gimbal. After restating the H the problem was gone. But when I went for the second flight (new battery) I experienced the same problem with the gimbal. Again, after restarting the H, the problem was gone.
