Spektrum DXs Transmitter
Stick Mode Change Guide
Mechanical Conversion
Mechanical conversion is required to change between Modes 1 and 2 or between Modes 3 and 4.
The mechanical conversion consists of the following steps:
1. Change the Throttle Ratchet
2. Adjust the Elevator Centering Screw
CAUTION: Always power off the transmitter, disconnect and remove the battery before adjusting
stick tension or friction straps. Not doing so could result in property damage or injury
Changing the Throttle Ratchet
1. Disconnect the battery holder or optional battery
from the transmitter and set aside.
2. Remove the six Phillips head screws that secure the
rear transmitter case half.
3. Put the transmitter face down on a piece of foam or
a towel and remove the rear case.
CAUTION: Use care to not pull or disconnect any of
the wires attached to the back transmitter half.
4. Locate the silver throttle friction straps on both
gimbals. One strap engages a serrated section on the
gimbal for a ratcheted throttle, while the other strap
engages the smooth section on the gimbal.
5. To change the throttle ratchet, loosen the throttle strap so it does not touch the throttle gimbal.
Tighten the opposite throttle strap to engage the desired throttle ratchet.
Adjusting the Elevator Centering Screw
When changing between Modes 1 and 2, or between Modes 3 and 4, you must adjust the elevator
centering screw.
1. Hold the Elevator or Throttle stick in the full up or
full down position when you are adjusting the elevator
centering screw. Holding the gimbal stick reduces the
load on the elevator centering mechanism and makes
it easier to adjust the centering screw.
2. Locate the gimbal where the elevator centering
spring is engaged. Use a Phillips screwdriver to tighten
the elevator centering screw. Tightening the screw will
disengage the centering spring.
3. Using a Phillips screwdriver, loosen the opposite
elevator centering screw until the lever engages.
