Ratcheted Throttle – Smooth Throttle Adjustment

Ratchet

1. Locate the throttle strap adjustment screws on both gimbals.

The ratchet set screw engages a serrated section on the

gimbal for a ratcheted throttle, while the tension set screw

engages a strap for smooth tension on the gimbal.

2. To engage the throttle ratchet turn the ratchet set screw

clockwise until the ratchet engages.

3. To disengage the throttle ratchet turn the screw counter

clockwise until the gimbal moves freely.

Smooth Tension

1. To engage the throttle tension, turn the tension set screw

clockwise until the Tension engages.

2. To disengage the throttle Tension turn the screw counter

clockwise until the gimbal moves freely.

Mode Conversion

Centering screw

You can select transmitter modes 1, 2, 3 or 4 for the NX20.

Converting the mode requires both a programming and a

mechanical change.

Programming Conversion

1. Change the mode within the System Setup -> System Settings.

2. Calibrate the sticks within the System Settings menu.

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/throttle tension; remove the

tension on the side that was throttle, and apply the tension on

the side that will be throttle.

2. Adjust the elevator centering screw. When changing between

modes 1 and 2, or between modes 3 and 4, you must adjust

the elevator centering screw.

a. 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.

b. Use a Phillips screwdriver to adjust the elevator centering

screw. Tightening the screw will disengage the centering spring.

Loosening the screw will engage the spring.

IMPORTANT: Do not remove the mode change screws too far

or you will have to open the case to put it back together.

Antenna Position

We recommend setting up your antenna to be positioned vertical

when you are in your most comfortable position for ﬂying. The

antenna may also be folded for storage.
