General Binding Tips and Failsafe BNF

• The included receiver has been specifically programmed for the operation of this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the receiver while binding.
• The orange LED on the receiver will flash rapidly when the receiver enters bind mode.
• Once bound, the receiver will retain its bind settings for that transmitter until you re-bind.
• If the receiver loses transmitter communication, the failsafe will activate. Failsafe moves the throttle channel to low throttle. Pitch and roll channels move to actively stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if needed, contact the appropriate Horizon Product Support office.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft’s ESC protects the flight battery from over-discharge using Low Voltage Cutoff
(LVC). Once the battery discharges to 3V per cell, the
LVC will reduce the power to the motor in order to leave adequate power to the receiver and servos to land the airplane.
When the 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 your Li-Po battery to about half capacity before storage. Make sure the battery charge does not fall below 3V per cell. Failure to unplug a connected battery will result in trickle discharge.
For your first flights, set your transmitter timer or a stopwatch to 5 minutes. Adjust your timer for longer or shorter flights once you have flown the model.

NOTICE: Repeated flying to LVC will damage the battery.

Transmitter Setup

IMPORTANT: After you set up your model, always rebind the transmitter and receiver to set the desired failsafe positions.
If your transmitter allows it, enable the throttle cut feature. Always engage throttle cut before approaching the aircraft.

Dual Rates
Low rate is recommended for the initial flights.

NOTICE: To ensure AS3X® technology functions properly do not lower rate values below 50%.
NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting Guide for more information.

Exponential
After your initial flights, you may adjust the expo value to better suit your flying style.

Transmitter and Receiver Binding

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. You need to ‘bind’ your chosen Spektrum™ DSM2/DSMX technology equipped aircraft transmitter to the receiver for proper operation.
Any full range Spektrum DSM2/DSMX transmitter can bind to the DSM2/DSMX receiver.

| Binding Procedure
---|---
| 1. Refer to your transmitter’s unique instructions for binding to a receiver (location of transmitter’s Bind control).
| 2. Make sure the flight battery is disconnected from the aircraft.
| 3. Power off your transmitter.
| 4. Place the aircraft on a level surface away from wind.
| 5. Connect the flight battery in the aircraft. The receiver LED will begin to flash rapidly (typically after 5 seconds).
| 6. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.
| 7. Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch instructions.
| 8. After 5 to 10 seconds, the receiver status LED will turn solid, indicating that the receiver is bound to the transmitter. If the LED does not turn solid, refer to the Troubleshooting Guide at the back of the manual.

For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.

Integrated Telemetry

This aircraft includes telemetry between the ESC and receiver, which can provide information including; RPM, voltage, motor current, throttle setting (%), FET (speed controller) temperature, and BEC (servo power supply) temperature.
To View Telemetry

1. Begin with the transmitter bound to the receiver.
2. Power on the transmitter.
3. Power on the aircraft.
4. A signal bar appears in the top left corner of the screen when the telemetry information is being received.
5. Scroll past the servo monitor to view the technology screens.

For more information about compatible transmitters, firm-ware updates, and how to use the telemetry technology on your transmitter, visit www.SpektrumRC.com.

SAFE® Select Technology

When SAFE Select is activated, bank and pitch limitations keep you from over- controlling the aircraft. Additionally, by releasing the controls in the event you lose orientation, SAFE Select will keep the aircraft level.
To activate SAFE® Select, flip the Gear channel switch to position 0. Return the Gear switch to position 1 to turn OFF SAFE Select and fly with just the assistance of AS3X® technology.
If you become disoriented or the aircraft is in a confusing attitude, flip the Gear switch to position 0 and release the sticks. With the aileron, elevator and rudder sticks in the neutral position, SAFE Select will automatically keep the airplane in a straight and level attitude.

Disabling and Enabling SAFE Select
By default, the SAFE Select function of your UMX aircraft is enabled and assigned to the Gear channel switch (channel 5). If you do not wish to have access to SAFE Select while flying, 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, throttle and gear channels are all on high rate with the travel set to 100%. Turn throttle hold OFF if it is programmed in the transmitter.

CAUTION : Keep all body parts clear of the rotor, intake and exhaust tube and keep the aircraft securely restrained in case of accidental throttle activation.

1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom corners and toggle the Gear switch 5 times
   (1 toggle = full up and down). The control surfaces of the aircraft will move, indicating SAFE Select has been enabled or disabled.

Repeat the process again to re-enable or disable SAFE Select.
DX4e, DX5e, DXe, and DXS Transmitters
The Gear switch is the FMODE switch on these transmitters, and the switch needs to be toggled between positions 0 and 2 when disabling/enabling SAFE Select.

ESC/Receiver Arming, Battery Installation, and Center of Gravity

CAUTION: Always keep your hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement.

Arming the ESC/receiver also occurs after binding as previously described, but the subsequent connection of a flight battery requires the following steps.
AS3X The AS3X® system will not activate until the throttle stick or trim is increased for the first time. Once active, the control surfaces may move rapidly and noisily on the aircraft. This is normal. AS3X technology will remain active until the battery is disconnected.

1. Remove the battery hatch from the fuselage.

2. Attach the battery to the hook and loop strip so the battery is against the motor mount. Center of Gravity (CG)
   At the wing root, measure the CG location 32mm back from the leading edge of the wing at the center section.

3. Lower the throttle and throttle trim to the lowest settings on your transmitter. Power on your transmitter, then waits 5 seconds.

4. Connect the battery to the ESC, noting proper polarity. Keep the plane immobile and away from the wind for 5 seconds to allow the AS3X system to initialize. A series of tones and a continuous LED indicates a successful connection.
   Spektrum or E-flite 2S batteries with a PH plug require an adapter lead. (SPMXCA327).

CAUTION: Always disconnect the Li-Po battery from the ESC when not flying to eliminate power supplied to the motor. The ESC does not have an arming switch and will respond to any transmitter input when a signal is present .

CAUTION: Always disconnect the Li-Po battery
from the ESC when not flying to avoid
over-discharging the battery. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting in loss of performance and potential fire when batteries are charged.

Control Direction Tests

You should bind your aircraft and transmitter before doing these tests. Move the controls on the transmitter to make sure
the aircraft control surfaces move correctly and in the proper direction. Make sure the tail linkages move freely and that
paint or decals do not adhere to them.

AS3X® Control Direction Test
This test ensures that the AS3X® control system is functioning properly.

1. Advance the throttle above 25% to activate the AS3X system.
2. Fully lower the throttle.
3. Move the entire aircraft as shown and ensure the control surfaces move in the direction indicated in the graphic. If the control surfaces do not respond as shown, do not fly the aircraft. Refer to the receiver manual for more information.
   Once the AS3X system is active, control surfaces may move rapidly. This is normal. AS3X is active until the battery is disconnected.

Control Centering

Before the first flights, or in the event of an accident, make sure the flight control surfaces are centered. Adjust the linkages mechanically if the control surfaces are not centered. Use of the transmitter sub-trims may not correctly center the aircraft control surfaces due to the mechanical limits of linear servos.

1. Make sure the control surfaces are neutral when
   the transmitter controls and trims are entered. The transmitter sub-trim must always be set to zero.

2. When needed, use a pair of pliers to carefully bend the metal linkage (see illustration).

3.  Make the U-shape narrower to make the linkage shorter. Make the U-shape wider to make the linkage longer.

Centering Controls After First Flights

For best performance with AS3X, it is important that excessive trim is not used. If the aircraft requires excessive transmitter trim (4 or more clicks of trim per channel), return the transmitter trim to zero and adjust the linkages mechanically so that the control surfaces are in the flight trimmed position.

Control Horn Settings

The illustration shows the factory settings for the control horns. Fly the aircraft at factory settings before making changes.
After flying, you may choose to adjust the linkage positions for the desired control response.

CAUTION: When these are incorrectly connected for the pilot’s skill level, unexpected aircraft responses to controls can result. This can cause damage to the aircraft and personal injury.

Flying Tips and Repairs

We recommend flying your aircraft outside in calm conditions. Always avoid flying near houses, trees, wires, and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards, or soccer fields. Consult local laws and ordinances before choosing a location to fly your aircraft.

Takeoff
Place the aircraft in position for takeoff (facing into the wind if flying outdoors). Set dual rates to low position and gradually increase the throttle to ¾ to full and steer with the rudder. Pull back gently on the elevator and climb to check the trim. Once the trim is adjusted, begin exploring the flight envelope of the aircraft.
Landing
Land into the wind. This is very important for this model. Fly the aircraft to approximately 6 inches (15cm) or less above the runway, using a small amount of throttle for the entire descent. Keep the throttle on until the aircraft is ready to flare. During a flare, keep the wings level and the airplane pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on all three wheels.
Failure to lower the throttle stick and trim to the lowest possible positions during a crash could result in damage to the ESC in the receiver unit, which may require replacement.

This aircraft is equipped with Over Current Protection
(OCP). This feature protects the ESC from overheating. OCP stops the motor when the transmitter throttle is set too high and the propeller cannot turn. The OCP will only activate when the throttle stick is positioned just above 1/2 throttle. After the ESC stops the motor, fully lower the throttle to re- arm the ESC.

NOTICE: Crash damage is not covered under the warranty.

Repairs
Repair the aircraft using foam-compatible CA (cyanoacrylate adhesive) or clear tape. Only use foam-compatible CA, as other types of glue can damage the foam. When parts are not repairable, see the Replacement Parts List for ordering by item number.
For a listing of all replacement and optional parts, refer to the list at the end of this manual.

NOTICE: Use of foam-compatible CA accelerant on your aircraft can damage the paint. DO NOT handle the aircraft until the accelerant fully dries.
NOTICE: When you are finished flying, never leave the aircraft in direct sunlight or in a hot, enclosed area such as a car. Doing so can damage the foam.
