A great step in the right direction to making OpenIPC a usable product. And a big upgrade over version 1. You can tell a lot of effort has gone into shrinking everything down to fit in a nice package.
The only thing that could use work is documentation on how to adjust various settings. If you're not getting good range you'll want to increase your txpower. I have a tutorial on how to do that here: https://youtu.be/7vp3ayxZwIs
