ZMR NX4 PRO Fixed-Wing Gyro Flight Controller
Technical Highlights
Three-Axis Aircraft Stabilization
The ZMR NX4 PRO provides gyroscope-assisted stabilization for the aileron, elevator and rudder axes of compatible fixed-wing RC aircraft.
Three Selectable Flight Modes
Rate Mode provides corrective stabilization, Hold Mode maintains the commanded aircraft attitude, and Gyro Off Mode passes direct transmitter control without gyro assistance.
Multiple Wing Configurations
Onboard configuration supports single-aileron, dual-aileron, flapperon, delta-wing and V-tail aircraft layouts.
Adjustable Axis Gain
Aileron, elevator and rudder gain can be adjusted independently with the onboard potentiometers, while the connected radio system can provide overall remote gain control.
Compact Fixed-Wing Installation
The lightweight controller is designed for installation near the aircraft center of gravity with its long side aligned to the fuselage heading.

Flight Modes
| Rate Mode | Applies gyroscope correction to reduce unwanted rotational movement. |
|---|---|
| Hold Mode | Provides attitude-locking assistance when the control sticks return to their neutral positions. |
| Gyro Off Mode | Disables stabilization so the transmitter controls the aircraft surfaces directly. |
Supported Aircraft Configurations
Conventional fixed-wing aircraft with one aileron channel
Fixed-wing aircraft with separate left and right aileron channels
Flapperon-equipped aircraft
Delta-wing aircraft
V-tail aircraft
Installation Notes
Supply the controller with a stable regulated DC 5–6V source.
Mount the controller firmly near the aircraft center of gravity.
Keep the label side facing upward and align the controller with the aircraft heading.
Select the correct aircraft type with the onboard switches before flight.
Start with a low gyro gain and increase it gradually during controlled test flights.
Verify that every stabilized control surface moves in the correct corrective direction.
Relearn the neutral position after changing the receiver, transmitter trim or sub-trim.
Disable transmitter mixing when the required delta-wing or V-tail mixing is handled by the controller.
This product does not provide GPS navigation, altitude hold, waypoint flight or return-to-home functions.

FAQ
Is the NX4 PRO the same as the NX4 EVO?
No. They belong to the same NX4 product family but have different voltage ranges, dimensions, weights and flight functions.
Which flight modes does the NX4 PRO provide?
The NX4 PRO provides Rate Mode, Hold Mode and Gyro Off Mode.
What input voltage does the NX4 PRO require?
Use a stable regulated DC 5–6V supply from a suitable receiver or BEC system.
Does the NX4 PRO support delta-wing and V-tail aircraft?
Yes. It supports conventional, dual-aileron, flapperon, delta-wing and V-tail configurations when the onboard switches and wiring are configured correctly.
Can the gyro gain be adjusted?
Yes. Aileron, elevator and rudder gain can be adjusted independently, and overall gain can be controlled from a compatible radio channel.
Does the NX4 PRO support GPS or autonomous flight?
No. It is a fixed-wing gyro stabilizer and does not provide GPS navigation, waypoint missions or return-to-home functions.
When should the neutral position be recalibrated?
Recalibrate after initial installation, replacing the transmitter or receiver, or changing transmitter trim or sub-trim.
B2B Procurement FAQ
What exact model should be stated on a purchase order?
Specify ZMR NX4 PRO Fixed-Wing Gyro Flight Controller. Do not identify the item only as NX4 PRO EVO because NX4 PRO and NX4 EVO are separate variants.
Does the word Plastic identify a separate version?
No separate plastic-version specification was found. The supplied archives show the same transparent plastic enclosure and appear to be duplicate product listings.
What should be checked during incoming inspection?
Verify the NX4 PRO model label, transparent enclosure, connector arrangement, cables, mounting pad, adjustment tool and physical condition.
Should the flight mode and voltage be confirmed before purchase?
Yes. Confirm the NX4 PRO model, Rate/Hold/Gyro Off functions and DC 5–6V input to prevent substitution with the NX4 EVO.
Are MOQ, lead time and packaging fixed?
MOQ, lead time, available quantity and packaging requirements must be confirmed during quotation.
