Instruction manual

C. Select two #0869 Washout Ball Links, two #106-07 M2x16 Pivot Pins, and four #106-08 M2 Circlips (a spare

is also included).

Note: The #106-08 Circlips are most easily installed on the #106-07 Pivot Pins by the following method: Lay

the circlip on a flat surface. Hold the #0106-07 Pivot Pin with a pair of pliers, while aligning one end of the

Pivot Pin vertically on top of the circlip. Tap the opposite end of the Pivot Pin with a small hammer into the

circlip. This will start the circlip onto the end of the Pivot Pin. Drill a hole in a piece of hard wood., slightly

larger than the Pivot Pin. Align the Pivot Pin/circlip over the hole and slightly tap the pin again. This will

drive the pin through the circlip. Repeat on the opposite end of the Pivot Pin after the #0869 links and #106-

05 arms have been joined together. The washout links #0869 should have no end play and pivot freely. If

they do not pivot freely, slide an Xacto blade or razor blade around the pin, in between the plastic link and the

washout arm. This will remove any plastic burrs.

D. Slide the assembled wash out unit down onto the main shaft and snap the two #0869 Washout Links onto any

two opposite #0109 Threaded Balls on the inner ring of the swash plate. The wash out unit should slide freely

on the main shaft. If there is drag, slightly polish the main shaft or the inside of the wash out hub #0571-1.

E. Select the previously assembled rotor head, the #0057 M4x4 Socket Set Screw, and the #0840-6 Dowel Pin.

Slide the rotor head down onto the main shaft and align the cross hole at the upper end of the main shaft with

the hole in the head block just below the flybar pivot bearings (Note: the larger of the two holes is for dowel

insertion and the smaller hole is for pushing the pin back out using a 1.5mm Allen tool). Alignment can be

accomplished by holding the rotor head rotating the main gear clockwise and viewing the holes from the side

at eye level.

Important Precaution:

There have been instances where builders thought they had all the holes aligned but

the main shaft was actually fully beneath the head block holes. To avoid this, it is helpful to confirm the

alignment by simply inserting a 2.0 or 2.5mm Allen tool in place of the dowel pin and lifting the model by the

rotor head. It pays to be cautious.

If the dowel pin will not fully insert through the main shaft with moderate pressure, rotate the head 180

degrees upon the main shaft and repeat. The dowel pin is always to be installed with the Achamfered end@

first. Once the dowel pin is properly fitted, secure it with the #0057 M4x4 set screw and a small amount of

Blue Loctite. Apply Blue Loctite sparingly and only to the set screw to avoid contacting the dowel pin and

making later servicing more difficult. Next, tighten the previously installed #0067 M3x14 Socket Head Bolts

clamping the base of the head block about the main shaft.
