GIMBAL STICKS
Ball-bearing construction allows both sticks to provide the ultimate in smooth, precise control. Stick
length
can be adjusted for optimum feel and control. Each stick consists of a base and a tip. To adjust, hold the base
tightly, then loosen the tip by turning it counter-clockwise. Adjust the stick tip to the desired length. Tighten
the stick by holding the tip in place and turning the base counter-clockwise until it’s tight against the tip.
STICK TENSION AND THROTTLE RACHET
Each control stick can be adjusted for softer or stiffer movement tension. A ratchet is also included for the
throttle stick which can be adjusted for feel depending on personal preference. Adjustment of either feature
requires removal of the rear of the Tx case as explained in the CASE SEPARATION AND ASSEMBLY
section below.
CASE SEPARATION AND ASSEMBLY
WARNING!
Failure to follow these instructions for separating and re-assembling the Tx
case can result in permanent damage to the transmitter and void the warranty. Contact
Hobby Services if you do not feel comfortable that you can safely and accurately perform
these steps.
ALWAYS disconnect and remove the batteries from the battery compartment FIRST. Failure to
do so can result in permanent damage to the Tx.
Remove the six screws from the back of the Tx case. Carefully pull the case rear away from the case
front and note exactly how all wires are routed inside the case.
After adjustments are made as described in other sections of this manual, close the case by fi rst carefully
tucking all cables back inside as when the case was opened. Align the case rear back onto the case front,
making sure that no wires are pinched between the case parts. Press the case halves together. Insert
the screws back into their positions and carefully tighten them
until snug
- making sure not to cross the
threads or over-tighten the screws. Re-connect the battery holder’s connector to the socket inside the
Tx. Insert the battery into the compartment, and carefully tuck the wires inside the cavity so they do not
become pinched when the door is closed. Close the battery door.
STICK TENSION:
Silver screws on the back of each gimbal are used to adjust the stick tension. Turn the
screw clockwise to make stick tension more fi rm. Turn the screw counter-clockwise to make stick tension
more light.
THROTTLE RATCHET:
A silver ratchet bar is mounted across the throttle gimbal. For airplane use, a
more fi rm ratchet feel might be desired for the throttle. In this case, turn the adjustment screw clockwise.
For helicopter use, less of a ratchet feel might be desired. Turn this adjustment screw counter-clockwise
to achieve the desired feel.
DIGITAL STICK TRIMS
The trim controls for the four main channels are digital. Holding the trim lever will cause the servo output
to move repeatedly. Trim positions are visible on the LCD’s home screen, and stored into that respective
memory. Changing the model memory will also cause trim settings to change accordingly.
For aircraft with glow engines, the precise position of the trim lever is helpful when determining the engine’s
preferred idle point. When the throttle stick is above 50% full throttle it will not be possible to trim the throttle
servo – even though the indicator on the LCD will move.
The amount of servo movement for each increment of a digital trim can be adjusted as desired, as explained
in the TRIM STEP SETTING section on page 10.
