IX. INSTALLING THE SWASHPLATE, WASHOUT UNIT AND ROTOR HEAD ASSEMBLY

Bag Required: 9A

Tools or Materials Required:

M1.5 and 2.5 Allen tools

Medium Phillips screwdriver

Small good quality pliers

Small flat screwdriver

Step 1: Assembling the Swashplate

Parts Required: Bag #

1 #0009 M3 flat washer (small) 9A

4 #0051 M3x3 socket set screws 9A

1 #0065 M3x12 socket head bolt 9A

3 #0107 M3x6 threaded balls 9A

4 #0109 M3x8 threaded balls 9A

1 #0159 M3x7 ball bearing 9A

1 #0217 Swashplate 9A

1 #0597-3 M3.0x4.75x4.60 brass spacer 9A

Refer to Drawing #9A

A. Select and examine the #0217 Swashplate. Note the four M3 threaded holes at each 90 degree position about

the base of the lower swashplate ring. Select four #0051 M3x3 Socket Set Screws and prepare each with Blue

Loctite. These four holes and set screws are for periodically minimizing any free-play that may develop as the

swash plate bearing wears (excessive free-play can cause inaccuracies in control inputs). Install each set

screw loosely. The adjustment procedure is to rotate the inner swash plate ring within the outer ring and

adjust the set screw until a slight irregularity or Anotchy@ feeling occurs, then loosen the set screw just enough

to return to a smooth rotation of the inner ring. Repeat the procedure for each set screw. In most cases, this

procedure should be done after every twenty gallons of fuel. This procedure can easily be done on an

assembled model by simply disconnecting the related ball links.

B. Examine the swashplate once again and note the positions for installation of the threaded balls into the inner

ring. Four of the six threaded holes (those at each 90 degree position) are utilized. Three threaded holes (at

120 degree intervals) are utilized for three #0107 M3x6 Threaded Balls in the outer ring. Select four #0109

M3x8 Threaded Balls and three #0107 M3x6 Threaded Balls. Prepare each with blue Loctite and install in

each position previously indicated.

C. Slide the swashplate down the main shaft. Rotate it so that one outer control ball is pointed rearward and the

remaining two balls are pointed forward at an angle on each side of the mechanics. This orientation will align

one empty threaded hole straight forward at the #120-44 anti-rotation unit.

D. Select one #0009 M3 Flat Washer, one #0065 M3x12 Socket Head Bolt, one #0159 M3x7 Ball Bearing and

one #0597-3 Brass Spacer. Slide each onto the #0065 Socket Head Bolt beginning with the ball bearing,

followed by the brass spacer and the washer. Apply a small amount of Blue Loctite to the exposed threads,

insert the assembly through the #120-44 anti-rotation unit then into the swashplate and tighten. The

swashplate should now be free to slide upon the main shaft without rotating.
