Hi!
Yes, my imu wire going trough sliprning on the pitch arm without problem.

Cheers

No, only at the board.

Slip ring contacts are not perfect, especially when they get older and are rotating. So even if one gets it working now, it could later on be problems. This is one of the reason I am avoiding them.

My question would be why to run I2C trough them? the only axis I see beneficing rotating more than 360 degrees is Yaw on arial gimbal, usually the board is below that and I think second IMU works better below Yaw.

If second IMU is needed above yaw and limitless yaw rotation in needed, then I understand the need, but maybe it would be good to keep the second IMU below the yaw and use FC connection. PWM signal would go trough the slipping much better than I2C.

Today i was testing continuous 360 on yaw. And yo know what? slip rings sucks!

The idea was to use hollow shaft motor with slip ring to deliver wires to battery and joystick above yaw. Within a day some wires on 2 slip rings stop working. First i assumed that the amperage from battery is too high for these thin wires (for sure). But then even power wires from joystick stop working.

So now i've abandoned the idea of continuous 360 - as slip rings seem to me really unreliable. Maybe large diam slip rings work better but these 12mm just suck. get away from them! haha
