Hi, i am very new to r/c helis. I have figured out all of the radio controls but one. I have a Futaba skysport radio and the control I can't figure out is the hov. pit. knob. I think it has something to do with bias between the main rotor and tail rotor controls. Can anybody explain it to me and maybe where I should have it set? I have a Kyosho Concept 30 SR.
