Here is a short demo of a payload release system on an Evo II (Pro) originally designed for a Mavic 2. I show the basic operation and test a drop from a few feet then from about 400' up. Sorry for the somewhat shaky video, this was my first time trying something like this. I had some audio issues as well in the first part, I hope I cleaned them up good enough.

Here is the system I used: https://www.amazon.com/gp/product/B08...
