How to Mount RC Helicopter Blades

Remove any blades that already exist on your helicopter with a screwdriver, and set them aside. Clean the mounting surface carefully with a clean dust rag to remove any particles, dust, dirt or other solid material. Clean the small, upward-facing holes where the blades' mounting nodes will fit as well.

Blow the surface of the helicopter's blade mount completely clean with a can of compressed air. Do this immediately before you intend to install the new blades to minimize the amount of accumulated dust as much as possible.

Attach your new rotor blades one at a time to the mount by sliding each rotor's mounting node into the appropriate guide hole and snapping the blades together to form a single spinning unit. Secure this unit with the included screws using a screwdriver. Make sure that each screw fits evenly and that the propellers' slopes all tilt in the right direction, i.e., upward in the direction that the rotors will be turning.
