General BNF Binding and Integrated Safety Tips
- The included receiver has been specifically programmed for use with this aircraft. Refer to the receiver manual for proper setup if it needs to be replaced.
- Stay clear of large metal objects when binding.
- Do not point the transmitter antenna directly at the receiver when binding.
- The orange LED on the receiver will flash rapidly when the receiver enters bind mode.
- Once bound, the receiver will retain its binding settings for that transmitter until you re-bind.
- In case of loss of communication between the receiver and transmitter, the integrated safety mode is activated. Integrated safety sets the throttle channel to a low throttle position. The elevator and aileron channels will move to stabilize the aircraft in a descending position.
- If you encounter problems, consult the troubleshooting guide or, if necessary, contact Horizon's after-sales service.
Low Voltage Cutoff (LVC)
A Li-Po battery discharged below 3V will not accept a charge afterwards. The aircraft's ESC (Electronic Speed Controller) protects the flight battery from over-discharge with the Low Voltage Cutoff (LVC) system. When the battery is discharged to 3V per cell, the LVC reduces motor power to the receiver and servos so they can support a landing.
When motor power decreases, land the aircraft immediately and replace or recharge the flight battery.
Always disconnect and remove the Li-Po battery from the aircraft after each flight. Charge the battery to about half its capacity before storing it. Check that each battery cell voltage does not drop below 3V. If you do not disconnect the battery, it will over-discharge. For the first flights, set your watch or transmitter timer to 5 minutes. Adjust the flight duration once you have flown the model.
NOTE: Repeated activation of the Low Voltage Cutoff (LVC) will damage the battery.
Transmitter Setup
IMPORTANT: After configuring your model, always re-bind the transmitter and receiver to set the desired integrated safety positions. If your transmitter allows, activate the Throttle Cut function. Always activate Throttle Cut before approaching the aircraft.
Dual Rates
Low rates are recommended for initial flights.
NOTE: To ensure AS3X technology functions correctly, do not reduce the rates below 50%.
NOTE: If you experience high-speed oscillation, consult the troubleshooting guide for more information.
Expo
After your initial flights, you can adjust the expo value to better match your flying style.
Computerized Transmitter Setup (DX Series, NX Series, iX Series)
Start all transmitter programming with a blank ACRO model (perform a model reset), then name the model.
Setting | Value |
---|---|
Reversing | Normal |
Dual Rates | HIGH 100%, LOW 70% |
Exponential | 10% for aileron, elevator, and rudder |
Servo Travel | 100% |
Timer | 5 minutes |
Throttle Cut (engine cut) | -100% |
Transmitter to Receiver Binding
Binding is the process that programs the receiver to recognize the unique code (called GUID - Globally Unique Identifier) of a specific transmitter. You must 'bind' your chosen Spektrum DSM2/DSMX aircraft transmitter to the receiver to ensure proper operation.
All Spektrum DSM2/DSMX transmitters are compatible with the receiver.
Binding Procedure
- Refer to your transmitter's instructions for binding to a receiver. (Access the bind function).
- Ensure the aircraft battery is disconnected.
- Turn off the transmitter.
- Place the aircraft on a flat surface, out of the wind.
- Connect the battery to the aircraft. The receiver LED will begin to flash (typically after 5 seconds).
- Ensure transmitter controls are in the neutral position and the throttle is low.
- Put your transmitter into bind mode. Refer to your transmitter's manual to perform this procedure.
- After 5 to 10 seconds, the transmitter's status LED will remain lit, indicating the receiver is bound to the transmitter. If the LED does not light up, refer to the Troubleshooting Guide at the end of the manual.
For subsequent flights, turn on the transmitter for 5 seconds before connecting the flight battery.
SAFE® Select Technology
The UMX Twin Otter features two flight modes controlled by channel 5: SAFE and AS3X. Switch A is the default Spektrum setting for channel 5. Position 0 is SAFE, position 1 is AS3X only.
When flying in SAFE mode, the aircraft will return to level flight as soon as the elevator and aileron controls are in the neutral position. Using the aileron or elevator controls will cause the aircraft to bank, climb, or dive. The amount of stick movement will determine the aircraft's flight attitude. Holding the control stick will drive the aircraft towards the preset bank and roll limits, but without exceeding these angles.
When flying in SAFE Select mode, it is normal to hold the control stick with a moderate aileron input when flying through a turn. For smooth flight in SAFE mode, avoid frequent control changes and do not try to correct minor deviations. Holding deliberate control inputs will command the aircraft to fly at a specific angle, and the model will make all necessary corrections to maintain that flight attitude.
Return the elevator and aileron controls to neutral before switching from SAFE mode to AS3X. If you do not neutralize the controls when switching to AS3X mode, the control inputs used for SAFE mode will be excessive for AS3X mode, and the aircraft will react immediately.
Differences Between SAFE and AS3X Modes
This section is generally accurate but does not account for flight speed, battery charge status, and other limiting factors.
Control Input | SAFE Select | AS3X |
---|---|---|
Control stick neutral | Aircraft automatically levels | Aircraft maintains the same flight attitude |
Holding a small amount of control | Aircraft banks or pitches to a moderate angle and maintains the same flight attitude | Aircraft continues to pitch or roll slowly |
Holding full control | Aircraft banks or pitches to preset limits and maintains the same flight attitude | Aircraft continues to pitch or roll rapidly |
Disabling and Enabling SAFE Select
By default, your UMX aircraft's SAFE Select feature is enabled and assigned to the Gear channel switch (channel 5). If you do not wish to have SAFE Select available during flight, you can choose to disable the SAFE Select functionality. AS3X will still be active when SAFE Select is disabled.
IMPORTANT: Before attempting to disable or enable SAFE Select, ensure the aileron, elevator, rudder, and throttle channels are all at full rates with the travel set to 100%. Disable Throttle Hold if it is programmed into the transmitter.
CAUTION: Keep all body parts away from the propellers and keep the aircraft securely immobilized in case of accidental throttle activation.
- Turn on the transmitter.
- Power on the aircraft.
- Hold both transmitter sticks towards the lower inside corners and flip the Gear switch 5 times (1 flip = fully up and fully down). The aircraft's control surfaces will move, indicating that SAFE Select has been enabled or disabled.
Repeat the procedure to re-enable or disable SAFE Select.
DXe and DXS Transmitters
Switch A is the FMODE switch on these transmitters, and the switch must be flipped between position 0 and 2 to disable/enable SAFE-Select. (1 flip = fully up and fully down). The aircraft's control surfaces will move, indicating that SAFE Select has been enabled or disabled.
Repeat the procedure to re-enable or disable SAFE Select.
Transmitters in Mode 1 and 2
Switch A is the FMODE switch on these transmitters, and the switch must be flipped between position 0 and 2 to disable/enable SAFE-Select.
ESC/Receiver Arming and Battery Installation
CAUTION: Always keep your hands away from the propeller. Once armed, the motor will drive the propeller with the slightest movement of the throttle stick. Controller arming occurs after the binding process described previously; however, for subsequent battery connections, you must follow the steps below.
AS3X
The AS3X system will not activate until the throttle stick is advanced past 25% for the first time. Once activated, the control surfaces may move rapidly and noisily on the aircraft. This is normal behavior. The AS3X system will remain active until the battery is disconnected.
- Open the battery hatch.
- Secure the battery to the hook-and-loop strap so that the battery is centered in the battery bay.
- Lower the throttle and turn on your transmitter. Activate the throttle cut switch.
- Connect the battery to the ESC, observing correct polarity. Keep the aircraft stationary and out of the wind for 5 seconds to allow the AS3X system to initialize. A series of tones and a solid LED indicate a successful connection.
A solid blue LED indicates the aircraft is in SAFE flight mode, and a solid RED LED indicates the aircraft is in AS3X flight mode. When the aircraft is in SAFE mode, the servos will move without increasing the throttle above 25%.
CAUTION: Always disconnect the battery from the controller when not flying to cut off motor power. The controller does not have an arming switch; it will respond to any stick movement when the signal is present.
CAUTION: Always disconnect the Li-Po battery when the model is not in use. You risk damaging the battery due to over-discharge.
Center of Gravity (CG)
The CG location is 23 mm (+/- 2 mm) behind the wing's leading edge. Check the CG with the model held vertically. Adjust the battery forward or backward to balance the model at the recommended level.
Control Direction Test
Turn on the transmitter, activate throttle cut, and connect the battery. Use the transmitter to control the aileron, elevator, and rudder. Observe the aircraft from the rear to verify control directions.
Elevator
- Pull the elevator stick back. The elevator surface moves up, causing the aircraft to pitch up.
- Push the elevator stick forward. The elevator surface moves down, causing the aircraft to pitch down.
Ailerons
- Move the aileron stick to the left. The left aileron moves up, and the right aileron moves down, causing the aircraft to roll to the left.
- Move the aileron stick to the right. The right aileron moves up, and the left aileron moves down, causing the aircraft to roll to the right.
AS3X Control Response Tests
This test verifies that the AS3X control system is functioning correctly.
- Activate AS3X by placing the throttle stick above 25%.
- Lower the throttle completely and activate throttle cut.
- Move the aircraft as shown in the illustrations and check that the control surfaces move in the direction indicated in the illustration. If the control surfaces do not respond as shown in the illustrations, do not fly the model. Refer to the receiver manual for additional information.
Once the AS3X system is activated, the control surfaces may move rapidly. This is normal behavior. AS3X will remain active until the battery is disconnected.
Control Centering
Before your first flights or after an accident, check control surface centering. If the control surfaces are not centered, adjust the linkages mechanically. Using the transmitter's sub-trims may not be able to center the control surfaces correctly due to the mechanical limits of the linear servos.
- The transmitter's trims may not be able to correctly center the aircraft's control surfaces due to the mechanical limits of the linear servos.
- If necessary, use pliers to carefully adjust the 'U' bend in the linkage (see illustration).
- Crimp the 'U' to shorten the linkage. Spread the 'U' to lengthen the linkage.
Control Centering After First Flights
For optimal AS3X system performance, it is important not to use trims excessively. If the aircraft requires significant trim correction (4 clicks or more per channel), return the trims to zero and mechanically adjust the linkages to compensate for the trims.
Float Installation (Optional)
Landing Gear Removal
- Pull the front landing gear assembly from the plastic support.
- Gently press the sides of the main gear and pull the main gear from the fuselage. If applicable, reassemble in reverse order.
Float Installation
- Assemble the floats as shown in the instructions provided with them, but use the struts supplied with the UMX Twin Otter.
- Note: The front and rear float struts supplied with the UMX Twin Otter are identical.
- Insert the flying wire into the slot at the bottom of the fuselage, tilting the wire as you insert it.
- Gently tighten the front flying wire and the spreader wire, then insert the flying wire into the slot.
- Repeat step 3 for the rear flying wire.
- Ensure the wires of both flying wires are fully inserted into the fuselage slots.
If necessary, proceed in reverse order to remove the floats.
Default Linkage Positions
The illustration shows the linkage positions on the control horns for the most acrobatic handling. Linkage position directly affects the aircraft's response.
CAUTION: If the position does not match the pilot's flying level, the aircraft may react in ways that could surprise the pilot. The aircraft may be damaged, and personal injury may occur.

Flight and Repair Tips
CAUTION: Always activate the Throttle Cut function before approaching the aircraft.
Check Your Radio System Range
Check the radio system range with the aircraft. Consult your transmitter's manual for range testing instructions.
Flying
We recommend flying your aircraft outdoors in calm or light wind conditions, or indoors in a large gymnasium. Always avoid flying your aircraft near homes, trees, power lines, and buildings. Also, be careful to avoid flying your aircraft in crowded areas such as parks, schoolyards, or football fields. Consult local laws and ordinances before choosing a flying site.
Takeoff
Position the aircraft for takeoff (facing into the wind if flying outdoors). Set dual rates to low and gradually increase throttle to full throttle, then steer with the rudder. Gently pull back on the elevator and climb to check for trim. Once trimmed, you can begin to explore the aircraft's flight envelope.
Hand Launch
To hand launch the aircraft, gently grasp the underside of the fuselage just behind the wing. We recommend launching in SAFE flight mode. Apply full throttle and release the aircraft by launching it...
Hand Launch
NOTE: Hand launching in AS3X mode is not recommended as it may lead to a crash. Always hand launch in SAFE mode.
- We recommend flying the aircraft without landing gear for hand launches.
- Always hand launch in SAFE mode, into the wind, at full power, and with high rates.
The control unit immediately detects the force of the hand launch in SAFE mode and automatically activates the hand launch assist feature. When this feature is active, the control unit automatically adds elevator to climb, causing the aircraft to climb at a higher angle for a few seconds. The SAFE standard mode is re-established shortly after launch.
Grip
We recommend holding the aircraft just behind the wings, as illustrated.
Follow-through
Launch over your shoulder, with wings level and the model's nose slightly up. Follow through with your launch by pointing your fingers towards the aircraft after releasing it. Avoid an arched launch that could cause it to nose over when you let go.
...gently forward, slightly upward (5 to 10 degrees above the horizon) and directly into the wind. As the model gains altitude and speed, reduce throttle to the desired level.
Landing
Always land facing into the wind. During the flare, keep the wings level and the aircraft facing into the wind. Slowly reduce throttle while gently pulling back on the elevator to gently land the aircraft on all three wheels.
NOTE: Always reduce throttle when the aircraft touches the ground during landing to avoid damaging the propellers and motor.
If you do not reduce the throttle stick and trim to the lowest possible position during a crash, the ESC in the receiver may be damaged.
Overcurrent Protection (OCP)
The aircraft is equipped with overcurrent protection. OCP protects the ESC from overheating and shuts down the motor when the transmitter throttle is too high or the propeller cannot turn. OCP will only activate when the throttle is set just above 1/2 throttle. After the ESC shuts down the motor, lower the throttle completely to re-arm the ESC.
Repairs
Damage resulting from a crash is not covered by warranty.
Repair this aircraft using foam-compatible cyanoacrylate glue or clear adhesive tape. Use only foam-compatible cyanoacrylate glue, as other types of glue are likely to damage the foam. When parts are not repairable, consult the Parts List and place your orders by part number.
Differential Thrust
When the rudder stick is moved to the left, the right motor will accelerate, causing the aircraft to yaw left in flight.
When the rudder stick is moved to the right, the left motor will accelerate, causing the aircraft to yaw right in flight.
Tip: Motors will not accelerate with rudder input when the throttle stick is in the idle position.
Post-Flight Checks
- Disconnect the battery (for safety and battery longevity).
- Turn off the transmitter.
- Remove the battery from the model.
- Store the battery safely away from the aircraft.
Motor Maintenance
Disassembly
CAUTION: DO NOT handle the propellers while the flight battery is connected to the ESC. You risk injury.
Propellers
- Gently grasp the spinner (A), being careful not to crush it, and pull while rocking the spinner back and forth to remove the adhesive. The propellers and spinner are glued together; any residual glue will need to be removed from the spinner or propellers when reusing these parts.
- Carefully remove the two M2 x 6mm machine screws (B) using a #1 Phillips screwdriver.
- Carefully remove the propellers (C) from the motor shaft.
Assembly
Assemble in reverse order.
- The left and right indicators 'L' (left) and 'R' (right) on the front of the propellers must face forward for correct propeller operation.
- Attach the spinner to the propeller using foam-compatible glue.
- Ensure the propeller adapter and motor mount are fully engaged with the motor.

CAUTION: We only perform paid repairs on electronic components and motors. Repairs involving mechanics, especially those of helicopters and radio-controlled cars, are extremely costly and must therefore be carried out by the buyer themselves.
