Go to boot up and it just sits there and spins. One of the top operators that I know has had many issues with the original Zenmuse having horizon issues during certain maneuvers along with not working at all on occasion. Where else can you connect to get the info from the FC? That's fine if you running a quad or a hexa but for an octo the F1 and F2 are use for motor 7 and 8. I think there's a few folks trying to hack the frame to do this by hand, but it's unclear if that will be possible. I love the airframe, but it looks like TBS may need to revise the upper plate to provide a feed from the FC. Unfortunately, in my case I am using the TBS Discovery Pro airframe which has a version of the AlexMOS controller embedded in the frame, apparently with no ability to pass the pitch/roll feeds in from the flight controller.
TBS DISCOVERY PRO GIMBAL TWITCHING FULL
The airframe body axes come from a full solution with compass and GPS.įrom what I read, the AlexMOS Simple BGC allows for pitch and roll inputs from the flight controller. However, DJI connects that gimbal to the flight controller, and therefore knows the airframe body-axes.

I have spent some time reviewing videos around the web, and I have yet to find an example of horizon drift on that gimbal. On the other forum, one of the contributors that struggled long and hard on this issue claimed that the only gimbal he tried that did not suffer from horizon drift was the DJI Zenmuse H2-3D. I suppose this is needed to account for centrifugal acceleration which skews the accelerometer data. there needs to be additional information, usually compass or GPS (GPS provides good quality heading data when in motion). I guess a straight IMU (just gyros and accelerometers) cannot keep track of the horizon perfectly. He had me cut some sample videos to show in class, as this is apparently a classical problem. I presented this problem to a colleague that teaches controls.
