1) Before proceeding to measure and install the
pushrods, make sure you have adjusted the
ybar to it’s optimal level (ybar paddles at and
parallel to the ground). Adjust the ybar until
the outer at spots align with the set screws
in the ybar control arms (set screws facing
upward and ybar control arms are ush up
against the seesaw).
2) Make certain that the ybar is equal in length
on both sides of the rotor head before tighten-
ing the ybar control arms. Set the ybar control
arms ush and level to the seesaw and tighten
the set screws using locktite.
It is very important that before you install the
pushrod linkages that your transmitter’s bat-
teries are fully charged. Then remove all the
servo horns from the servos and center all the
mechanical or electronic trims on the radio.
Due to the different types of radio and servos
that are chosen to install into the helicopter,
match each pushrod to the lengths in the table
for optimum setup.
Note: All dimensions are in millimeters and
are measured from the centers of the con-
trol balls or ball ends.

These lengths should allow for approximately +/- 12 degress of pitch
with 0 degrees at center stick (typical 3D setup).

taching a master pushrod and match
new pushrods as they are assem-
bled. Gauge has millimeter scale for
accurate lengths center to center.

blades. Self centering weighted
indicator offers easy to read
pitch numbers during setup. No
more need to eyeball the amount
of pitch that’s being dialed in.
