STEP 32

From parts bag 7, assemble the Blade Grip Halves over the bearings with the nuts on the gearbox side

using two 2x10mm Phillips Machine Screws and 2mm Nuts using threadlock. Snap the ball on the tail

rotor grip into the adjoining pitch slider link on both sides.

Install the Tail Rotor Blades using two 3x16mm Socket Cap Screws and M3 locknuts. Note the

direction of the blades on the diagram, the leading straight edge of the blade should be on the same side

as the ball on the blade grip.

over the hole in the shaft )

and secure with one 3x4 mm

Set Screw using threadlock.

Using one 3x16mm Socket

Cap Screw, attach one Ball

Bearing on each side of the

hub assembly using threadlock

( apply the threadlock to the

threads in the hub to avoid
