Sorry it's taken so long to get back to this. Life's been a bit nuts. I went out this morning and shot some new footage just so it was all fresh in my mind. So, here it is.
Flight Control V0.0.2.26
Gimbal V1.1.5.5
When starting up the EVO, the camera goes through it's calibration process and begins horizontal on the ground.
By the time I reached altitude, it was no longer horizontal.
In the first video I'm in precision mode and the camera is rotated down to about -7deg. Notice at about the 3 second mark the camera raises a bit and begins to rotate clockwise. This is when I began to yaw to the right. This isn't with full stick. I'm about 30-50% stick at this point
in precision mode.
By the time I get to the end of the yaw, the horizon is past horizontal level in the opposite direction.
At about 26 seconds, I'm beginning my yaw to the left. The camera rotates counter-clockwise so the horizon is no longer level before the EVO begins to spin.
At 54 seconds I'm yawing to the right again, the camera raises a bit and rotates clockwise. At 1:21, I rotate the camera up to 0deg, and wow. I have the left prop in the shot. What the what? That caught me by surprise. As the EVO sits without being moved, the camera is ever so slowly rotating counter clockwise.
The second video is shot in standard mode just to emphasize how bad the problem is. Again, the left front prop makes a guest starring appearance throughout the shot.
I've examined the rubber dampers that suspend the gimbal and they look fine from what I can see. I have to suspect that the firmware update has caused the issue as I didn't have it before. Just to ensure that I did have a good firmware update, I've updated it 3 more times (once for each battery). I've also spent an evening and almost a half a battery calibrating the gimbal several times.
Now, the bigger problem is that I'm supposed to shoot a wedding in two weeks and the EVO just isn't going to be able to do it in this state. So, I basically have two questions. Am I correct with my suspicion of firmware? And, if so, is there a way that I can downgrade to the previous firmware to test that theory out?
Thanks,
Rick
