This link should have the entire HBK2 TX manual down at the bottom of the thread. You can also download this manual as well as an updated K2 manual from the Esky website (

My K2 hovers at mid throttle with the left (HOV.PIT) knob set at the 2:00 position while a 12:00 setting on the right (PIT.TRIM) knob seems to give a reasonable headspeed and servo response. The setup on your K2 may require slightly different settings.
Good luck and good flying!
P.S. There is no such thing as a "dumb" question.
