ok this is from memory Your rx is marked with channel number soooo.
when you plug in the connector the black or dark wire on it is towerds the bottom of the rx, next wire is the red and the top wire is the signal wire which is usually white.
chan 1 is the Ail servo back side on left (behind pilot)
chan 2 elev servo thats the one on the front of the heli
chan 3 is the conn from the esc
chan 4 is the wire from the gyro
chan 5 is empty as it is used for the single wire from a hh gyro
chan 6 is the pitch servo thats the one on the backside on the RIGHT behind the copilot

you know that when you hook your motor up if it turns the wrong way you reverse any two wires on it? that will reverse the motor.
btw as long as you went brushless you didnt mention what kind but if its NOT an Esky you may have to program the ESC to turn the brake off and set for a brusless motor and soft start etc.
Hope this helped you a little [8D]
