Updates:
. My KK2.1 flight controller ended up being defective, after much effort and several props I removed it.
. After a not-so-interesting crash, one of my arms snapped almost clean through.
. Overall I suppose I got what I paid for, which didn't amount to much.

First off, apologies for the audio. I discovered after recording that the Mobius recording in MP4 has audio sync issues, Also that should have been talking louder.
This video does not cover the setup of the KK2.1 controller. There are a bunch of setup guides and the manual is a quick read. I didn't need to mess with the PID settings to get a good initial flight. https://www.youtube.com/watch?v=M6HndVz5adM
