The RC helicopter's receiver is used to receive the controller's signal and allow the helicopter's motor, rotation strength, pitch and rudder to be controlled remotely. Based on the RC helicopter's design and capabilities, the receiver will have between three and five channels. Each channel needs to be hooked up to a servo wire. It is important that the servo wires are insulated and protected from any moving parts on the helicopter. They must also be secured well to avoid vibrations and damaging other parts, like the receiver's antenna, during flight.
Gather the wires on the assembled helicopter.
Label the wire leads with masking tape so that you will know which servo they connect to.
Plan out the route for the wires to travel from the servos to the receiver. Avoid any moving parts of the helicopter.
Insulate the wires with braided sleeving if they must be routed by moving parts. You may place more than one wire through the same piece of braided sleeving.
Secure the wires along the route to the helicopter frame with zip ties or velco straps.
Wind the excess wire into a coil to shorten it. You may use a screwdriver as a guide to wrap the wire around and then slide it off.
Plug each wire from the servos into the receiver channels. Each receiver channel is labeled for the servo wire it needs. The labels on the servo wires and the receiver channels should match.
Mount the receiver to the receiver plate using double-sided tape.
Secure the coiled wires to the helicopter with zip ties or velcro straps. Avoid having any of the coiled wires touch the receiver's antenna.
Wires that are not connected properly will adversely affect the helicopter's flight. They will interfere with the receiver's ability to properly communicate with the helicopter's steering mechanisms.
