How to Flip a KK2 Quadcopter
Short Video on how to do flips and rolls with a KK2 quadcopter. I just started doing them my self one day ago. I crashed a bunch trying to figure out the best PI settings and stick scaling settings which i have at the end of the video. I had a hard time finding a good video on youtube on setting up and how to do your first flips, so i made this video. I am not an expert acrobatic pilot so anyone should be able to do flips and rolls as long as you can fly comfortably in Acro Mode with your KK2 Controller. My KK2 is upgraded to the ver 1.6 firmware but i think these settings should work well on ver 1.5 firmware, but i am not sure about ver 1.2 firware that comes on a stock KK2 controller from hobbyking.
I found it easiest to start low, gain attitude, reduce throttle till it stops rising, full aileron (left or right), flip then back on the power quickly do it does not drop too quickly.
rolls use aileron (left or right), flips use elevator (forward or backward)
