Things You'll Need
Instructions
Use a Phillips screwdriver to remove the retaining screws holding the two plastic housing-panels together. Gently remove the top plastic panel to expose the wires and motherboard of the control pad. The control pad is surrounded by two plastic panel-plates, much like a clam shell. Inspect all wire connections for damaged or disconnected wires. If a wire has been damaged, use wire strippers to remove one inch of the rubber coating from the damaged end of the wire.
Unscrew the retaining screw of the damaged wire and remove the damaged piece of wire. Thread the newly exposed end you have made under the retaining screw and tighten the screw. Blow compressed air on the wires to clean the pad. Replace the control pad housing.
Open the battery panel on the back of the control pad. Remove the old batteries. Look for any corrosion. If corrosion is present, pour cola into a cup, dip a toothbrush in the cola and scrub off the battery corrosion with the cola-soaked toothbrush. Cola breaks down battery corrosion and helps clean battery terminals. Wipe off excess cola with a rag.
Place new batteries in the panel and close the battery housing. Turn the helicopter and control pad on. Test the controls with a Bladez helicopter flight around the house.
