This was the first 3S pack, so please forgive the lack of flow, I was just testing out flips and punchout ;) Jello in the punchouts is from too high p-gain.
Had great fun with the EMAX Babyhawk running 2S, but it lacked a little power when recovering from bigger dives and hard turns. It's rated for 2S, so I wasn't sure it would survive 3S. I had to lower the PIDS a little, and it's still getting some oscillation on punch outs, but it flies FANTASTIC. I also removed the prop guards and changed the power connector to XT30. Running Betaflight 3.1.7 w/ DSHOT 600 (requires a wiring mod for motor 4)
3 minutes flight time, battery came down slightly warm @ 3.78v per cell, and the motors were barely warm to touch.
