Remove the three screws holding the two halves of the tail rotor gearbox together and open the gearbox, leaving the shaft assemblies on the right side. Insert the tail boom so that the keying hole is engaged. Insert the drive wire into the forward input shaft and align the shiny flat spot with the allen screw hole and secure with the two 4mm allen screws. Re-assemble the two gearbox halves.
Insert the tail boom assembly into the mainframe. Insure the flat of the drive wire is properly engaged into the front drive shaft and the round keys are properly keyed into the slots. Secure with the four long bolts and lock nuts. Screw the coupler (15 to 20 turns) to the front of the tail rotor control rod on the tail boom. Screw in the ball link to the front end (with the bend) of the other tail rotor control rod (15 to 20 turns). From the servo tray area, insert the remaining threaded end of this rod through the large tail rotor rod guide at the back of the top frame and screw into coupler (15 to 20 turns). Now adjust the length from the front ball link to the rear one at the tail rotor bellcrank to 894mm. Attach the front link to the tail rotor servo wheel.
Attach the two tail boom support struts to the horizontal fin mount on the tail boom with the two screws supplied and to the lower rear of the mainframe assembly using the two M3x9x4 plastic spacers and the appropriate hex bolts with locknuts.Attach the vertical and horizontal fins to the tail boom assembly. Cut out the appropriate decals and apply to the fins.
	Attach the two 106mm pushrods (shorten to 104mm for training) to the short balls on the swashplate and to the short balls on the bell mixers on the main rotor blade grips. NOTE: For faster cyclic response in 3D you may want to change the bell/hiller ratio by moving the A-arms from the washout assembly to the short balls on the inner star of the swashplate and attach these 106mm rods to the longer balls on the inner star.
	Attach the 103mm throttle control rod to the throttle servo and the throttle arm on the carburetor. Be sure that when the throttle collective stick is in the middle, that the throttle servo arm is straight up, and that the carburetor barrel is half open and its’ control arm is also pointed straight up. Shorten the 104mm collective control rod to 102mm for training or to 100mm for 3D. Attach this rod to the collective control lever and collective servo. Be sure the collective servo wheel is attached so that at mid stick is pointed straight up.
	Lengthen the two 156mm aileron control rods to 158mm and attach to the two balls on the aileron servo wheel and to the two aileron bellcranks. Shorten the 137mm elevator control rod to 135mm and attach to the elevator servo arm and elevator bellcrank.
