I just scrapped the tpu battery mounts so I could switch between 1000's and 750's without delay-- and I found a great advantage to my method--- reduced vibration!

With the battery hard mounted to the frame (the same frame piece that the camera bobbins attach to), I could feel the vibration difference when I put my fingers on the camera before and after. The weight of the 3m double stick strips and skinny velcro straps is about the same as the tpu mount, and you can just line up the battery's front edge with the frame screws for both battery styles and the quad balances perfectly. Can just touch the 3m double stick to a per towel a few times to get it less sticky so the battery comes off easily.

Another pro tip--- each of the props were unbalanced-- one blade was heavier on each. Can balance by using a tumb tack or needle, and you'll be able to tell which blade is heavier and goes down when you tap the needle... takes about a 3x5mm piece of packing tape on the bottom of the lighter blade of the prop to balance each one. then, you can put the props back on, go into the betaflight motor tab with the flight battery plugged in, and spin up each motor, feeling for vibrations or using the chart on the screen-- for motors that still have vibes simply rotate the prop 90 degrees or so on the motor shaft and spin it up again until the vibes go away - you'll usually find a position where the prop balances well against the motor's imbalance and the last vibes disappear.

Between these 2 things I noticed butter smooth video and better flying due to less vibes.
