Adjust Stick Tension
• Adjust stick tension using the screws on the stick gimbals
through holes in the back of the transmitter.
• Move the grips on the back of the transmitter case to see
holes marked with an M (for Mode), a vertical arrow and a
horizontal arrow.
• Turn the screws in these holes a small amount using a small
Phillips screwdriver to adjust tension on the vertical and
horizontal gimbals.
When changing modes that require the throttle and elevator to
be moved from one side to the other (for example, when chang-
ing from Mode 1 to 2), hold a stick fully up or fully down while
tightening or loosening the centering screw. Holding the stick
decreases the load on the mechanism, making screw adjust-
ment easier.
NOTICE: Always do a test of stick tension while turning these
screws to ensure stick tension is not too loose or too tight.
Tightening a screw too much can damage a spring. Loosening a
screw too much can let a spring fall off and cause short- circuit
in the transmitter.
CAUTION: Always power off the transmitter, disconnect
and remove the battery before opening the transmitter case. Not
doing so could result in property damage or injury.
APPENDIX
Mode Conversion
You can change Modes in your DX7s transmitter among Modes 1, 2, 3 and 4. Make mode changes in the transmitter using the
System Settings Screen. Exit the System Settings Screen to save the new Mode number. Power off the transmitter and disconnect
the battery.
Adjust Friction Straps
• Remove rubber plugs from the back of the transmitter to
adjust friction straps on vertical gimbals.
• Use a small Phillips screwdriver to tighten or loosen the
screw for either the ratchet or smooth friction strap.
• Always install the plugs after adjusting the friction straps.
Move Throttle Stops Between Gimbals
Move the throttle stops or wedges between the left and right
control sticks when changing between Modes 1 and 2 or
between Modes 3 and 4. These wedges limit the range of the
throttle for improved throttle feel.
1. Place the front of the transmitter face down on a foam pad
using care to not push hard on the transmitter which could
damage the gimbals or switches.
2. Carefully pull back the rear grips so two screws show.
3. Remove these Phillips screws and four others from the back
of the transmitter.
CAUTION: Make sure no wiring is damaged when
opening the transmitter or moving parts in the transmitter.
4. Remove the side rubber panel from the right side of the
back of the case (looking from the back of the case).
5. Carefully open the right side of the case and put the back of
the case down to the left of the front of the case.
