4. The replacement spindle is supplied with one bolt and washer
pre-installed with thread locking compound, and the other bolt and
washer are partially installed using thread locking compound.
Remove the partially threaded socket head cap screw from the
spindle using a 1.5mm allen wrench. 5. Insert the 1.5mm allen wrench into the remaining bolt in the
spindle. Insert the replacement spindle into the blade grip where
you removed the screw. When performing the next step, hold onto
the blade grip on the opposite side of the rotor head. Use the
1.5mm allen wrench to press the replacement spindle through the
head which will push the old spindle out the other side. Discard old
spindle. Make sure no parts fall out during this step.
7. Reinstall the main rotor blades using the 1.5mm allen wrench as shown above. Be sure that the blades are mounted with the leading
edges facing the correct direction as shown above. When the helicopter is held up on its side the main blades should support their own
weight. When held in this position and shaken the blades should fall equally. Happy Flying!
