MODIFYING THE SERVOS FOR INSTALLATION
4 & 5. (optional) Trim both servo mounting flanges from each
servo.
6. (optional) Cut the protruding portions from the bottom of
the servo case as pictured. This will allow the best fit in the
model. Note that the cut is made on the far end from the
servo lead.
7. (optional) After modifying the servo it should appear as
pictured.
8. Before entering section 3 you will need to remove the
pushrods from the swashplate of the helicopter.

MOUNTING YOUR SERVOS
1. Insert the pushrod into the hole on
the servo arm farthest from the output
(10-12mm from center).
2. Place servo tape on the mounting
surface before mounting the servo.
3. Position servo so that the arm can
travel freely and the pushrod is straight
up and down.
4. Once the mounting position of the servo is
determined carefully mount the servo to the mast
tower. If the servo has a label on the same side
that will mount with double sided tape, peel off
the label and clean the surface using rubbing
alcohol.
5. After mounting the servo place the plastic ball
link on the corresponding control ball on the
swashplate. Only use the large opening on the
ball link. (see below)
6. There are only 2 servos needed. When
mounted they should appear as pictured.

7. Turn the radio on with all sticks and
trims centered except for throttle. Make
sure the throttle is in the lowest position.
Use servo horns that have a hole 10-
12mm out from the servo pivot center and
place it as pictured (parallel to swashplate
and frame). Verify also that flybar paddles,
swashplate & servo horns are parallel to
each other and also 90 degrees to the
main shaft. You can adjust the lengths of
the pushrods by twisting the ball links
clockwise to shorten the length and
counterclockwise to increase the length.
