Hi Kyoo, I am also back here I am sorry that I didn't follow your case, because I was thinking our aftersales team has already supported yougood. I've repeatedly tried to get a response from Peter@SJCAM on whether or not the high pitched buzzing on the M20 has been fixed, with no response from him after several follow ups.
Do you think we can get more original uncut / raw drone footage shot using your SJCAM's? If so, we have someone who can edit your videos and make a compilation. We'd give you credit for footage when posting to social media of course.M20 on a Q333 quadcopter ( a mini dji inspire 1 clone)
