The blade grips / holders are black clevis like objects which clamp down on the root of each blade and hold it to the main shaft. If one of these becomes damaged, use this procedure to replace it:
- Remove the both of the rotor blades that the blade grips are holding by following the instructions above.
- Lay the RC helicopter on its side and observe the two screws that hold the blade grips together and on the main shaft. This picture shows one screw removed, viewed from the bottom of the helicopter.
- Unscrew the blade grips and keep the screws in a safe place where they can’t roll away.
- Replace the broken blade grip and install the screws.
