Without going into any detail to send you to sleep, my Zenmuse H3-3D v1.1 is clearly unbalanced - it doesn't stay in the same position when powered off. When powered on, I can hear the motors working quite hard as it runs through the start-up sequence to get it straight, and even when finished it tends to point slightly to the left. I also get a "whining"/"beeping" noise which appears to be an issue with the flimsy cable connected to the GoPro. Would you recommend: a)Returning this for a new replacement and hope everything is perfect, but run the risk of the same problem or worse issues with the replacement? b)Sticking with what I have, and trying to balance it out using tape as I've seen elsewhere on the forum?
