My Yi (original) is too light by itself to meet the minimum weight requirement (125g) for my Zhiyun Crane-M gimbal. I have the waterproof case to add weight but would rather not use it as it muffles the audio recording. I also have a plastic frame that connects to a saddle with a tripod mount, but it's still 15g short of minimum. It works, but I sense a vibration coming from the gimbal which I suspect is caused by the camera not meeting minimum weight. Any advise how I can add weight to the Yi to make 125g? Maybe something with tripod mounts that go in between the gimbal plate and the camera?
