Have just gotten a HBK2 with the E-sky controller included. Have read the instructions booklet but it didn't give me much info. I've had a E-sky lama before so the 4 channel controller from e-sky is no problem to use. But the 6-channel one which I got with the HBK2 has got some extra switches one it. One at the top left corner and one at the top right one. And one more at the top left side of the controller which has the text "gyro.sw". And I wonder what these switches are for. Can anyone here help me?
