Here is Mantra flying some aerobatics using the Openpilot Coptercontrol flight board. Love it!
Here are some great videos by Warthox that show his stick movements for aerobatic flying.
Practiced my flips, rolls and loops today. My PID settings allow for real fast flips, which are getting easy to do (and at lower altitudes). It is doing large loops that I think are tricky, have to time it and judge how much nick/roll to give it.
Learning to do fast flips and rolls with Jötunn. Thanks to Warthox for the MWC gain settings. Best viewed in HD and fullscreen to see what is going on. Wide gopro makes things look small.
