Properly routing electrical wires in a radio controlled helicopter kit will not only enhance your helicopter’s appearance but will also prevent future performance issues. Poor wiring techniques could result in wires being cut or frayed by moving parts, such as the main rotor blade, and a loss of power resulting in a crash. Protect wires from damage with a good installation to the base component and you will be rewarded with hours of enjoyment.
Begin wiring your model helicopter by washing your hands free of dirt and oil with hand soap to ensure a good electrical connection. Dirt and grime buildup could cause the craft to perform poorly.
Open your plastic model kit and arrange the electrical pieces in order of attachment to the main component frame as outlined in the instruction manual that is included with the kit. Using a step-by-step approach will help you avoid mixing up electrical wires, which could cause performance issues.
Clean all surfaces where double sided tape will be applied, using rubbing alcohol and a lint free towel. Clean surfaces will adhere the tape better and ensure a long-lasting grip.
Label each servo with a piece of tape to identify which channel on the base component it belongs to. Mislabeled wires will cause the helicopter not to work properly. Servos are wires attached to connectors that attach to receivers that provide power to operate certain parts of the helicopter, like the rotor blades and engine.
Mount receivers that do not have an outlet source (commonly called a speed control or governor) by wrapping them in a piece of foam rubber. Attach a rubber band or Velcro strap to secure it to the base to protect it from coming loose during vibration of the helicopter.
Install the servo extension leads that are attached to the main component into the receiver. Look for a way to lay the wires so they don't come in contact with any hot or turning objects, like the engine and exhaust components on a fuel powdered model or the motor and speed control on an electric model.
Secure the routed wires with a short piece of fuel tubing and zip ties. Place the tubing on top of the wires and firmly secure it with a tie to the base. Braided sleeves or spiral tubing may also be used to protect the wiring and keep it in place with a tie.
Complete the final inspection by carefully looking over the model, looking for loose wires, tape and tubing. A quality inspection will ensure nothing is missing. Finish the model by attaching the cover and the remaining parts to the helicopter.
