I recently got my RSC 2, today I balanced the gimbal, did the balance test (all excellent) and the autotuned, I was using the joystick and tilted the gimbal up (lens to the sky) and the motor started to make a noise, has anyone has this issue?
Sony A7III with sigma 24-70mm f2.8

I noticed it only seems to make the noise when the gimbal is upright on the tripod, I'm not sure what this could be?

All the other movements are normal.

Thanks in advance to anyone that takes the time to read/reply!

I just got that effect with my newly bought RSC 2. When tilting over +90 degree, there is an annoying, squeaking noise, that one wants to stop immediately. It stops when going below +90 degree again. :-( The Gimbal is perfectly balanced, and as you said any other movement is normal
I did another calibration, and it vanished... not very satisfying, but for now an 'one time error'
