I believe this is one of the lighter DJI setups available today. I previously owned a Firefly Nano 20 that weighed around 42.xx grams stock vs this one coming in around 5 grams lighter. The Falcon Nano isn't the lightest DJI camera but it's all I had on hand and prices for caddx cameras have gone up a bit, though I don't see the Falcon on runcams website anymore either. The battery mount was designed by me to fit 2s 450 - 2s 850 batteries by stretching in size. This was also designed to be printed without supports, though the durability is obviously going to take a hit. I have a more durable version, for those interested in either: https://www.printables.com/model/575579-nanofly20-1s-to-2s-conversion-battery-mount
