I want to install an Spektrum AR6115e receiver into a 4 channel coax heli. There are four leads from the 3 in 1, 1 each for the aileron and elevation servos, these I believe are self expanitory and go to the AILE and ELEV pins. My problem is with the motor leads, what pins do the outer and inner shaft motors go on. I'm guessing probably the pins for THRO and RUDD but which ones. The existing receiver just adds to the confusion since their terminology is different.
