Tyro79 - Easy build, very little soldering required. The flight controller comes flashed with Betaflight 3.5.1 but is not at all configured, or wasn't in my case. This is a start to flight build, setup, and fly video, very long and only detailed where i had trouble.
Build tips: 0:20 to 15:30
Betaflight flash and setup: 15:30 to 30:45
BLHeli suite setup: 30:45 to 33:45
Flight with commentary: 33:47 to end
Update: Flash to betaflight 4.0 development is FAR better for the pid settings and feel.
