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, firmware updates, and how to use the telemetry technology on your transmitter, visit www.SpektrumRC.com.

ESC/Receiver Arming, Battery Installation and Center of Gravity

NOTICE: Always keep material or debris away from the intake. When armed, the rotor will turn in response to throttle movement and could ingest loose objects.

The UMX A-10 requires a 3S 850mAh Li-Po battery with an IC2 connector (SPMX8503S30 recommended). Add a piece of hook and loop material (hook side) to the side of the fuselage along the battery compartment. Add a small piece of hook and loop material (soft side) to the side of the battery at the same end as the power lead. It is important to only use a small piece to prevent the battery from shifting. Using too large of a piece will make it difficult to remove the battery and may lead to fuselage damage.

Arming the ESC/receiver also occurs after binding as previously described, but subsequent connection of a flight battery requires the following steps.

1. Lower the throttle and throttle trim to the lowest settings on your transmitter.

2. Remove the battery/canopy hatch from the fuselage and install a flight battery (A) all the way to the back of the battery comportment.
   
   Center of Gravity (CG)
   The CG location is 32-34mm back from the leading edge of the wing at the root. Balance the airplane inverted on this recommended CG mark with all landing gear installed. Adjust as needed by sliding the battery forward or back.
   

3. Power ON your Transmitter, then wait 5 seconds.

4. Connect the battery to the ESC, noting proper polarity. Keep the plane immobile and away from wind for 5 seconds to allow the AS3X system to initialize.
   
   A successful connection is indicated by:

   • A series of tones
   • A continuous LED

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.

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 toturn 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 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 the these transmitters, and the switch needs to be toggled between position 0 and 2 when disabling/enabling SAFE Select.

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. Ensure SAFE Select is OFF.

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

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

4. Make the U-shape narrower to make the connector 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. Do not trim the aircraft while SAFE Select is active. Always trim the aircraft in AS3X mode. If the model 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.

Factory Control Horn Settings

The illustration shows the factory settings for linkages on the control horns. Linkage connections on the control horns directly affect aircraft response.

Landing Gear Removal

The landing gear may be left installed or removed to suit your flying area. We recommend using the landing gear when you can take off and land from a smooth surface. If you have long grass you may choose to remove the landing gear, in which case you will need to hand launch the aircraft and belly land.

1. Carefully pull the gear straight out of the retainer clip that secures it into the fuselage.
   

When needed, assemble in reverse order.

Flying Tips and Repairs

Range Check your Radio System

After final assembly, range check the radio system with the aircraft. Refer to your specific transmitter instruction manual for range test information.

Flying

We recommend flying your aircraft outside in no greater than moderate winds or inside in a very large indoor facility. Always avoid flying near houses, trees, wires and buildings. 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.

Hand Launching

Hold the aircraft above the wings between the canopy and motor nacelles. Apply full throttle and launch directly into the wind with an underhand toss with the nose pointed up at approximately 45 degrees above the horizon.

Tip: Electric ducted fan (EDF) aircraft require airspeed for control and have less control authority at slow speeds without a propeller slipstream moving air over the control surfaces.

Takeoff

Taxi the aircraft in position for takeoff (facing into the wind if flying outdoors). Gradually increase the throttle to full power, holding a small amount of up elevator and steering with the rudder. Climb gently to check trim. Once the trim is adjusted, begin exploring the flight envelope of the aircraft.

Landing

Always land into the wind. Fly the landing pattern with a slightly nose high attitude. Use throttle management to control the decent rate of the aircraft.

During 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 the main wheels or to belly land without landing gear.

NOTICE: Always fully lower the throttle when landing the aircraft to prevent intake of foreign objects, which can damage the ducted fan and motor.

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.

Over Current Protection (OCP)

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

Low Voltage Cutoff (LVC)

LVC is a function built into your ESC to protect the battery from over- discharge. When the battery charge is low, LVC limits power supplied to the motor. The aircraft will begin to slow and you will hear the motor pulse. When the motor power decreases, land the aircraft immediately and recharge the flight battery.

NOTICE: Repeated flying to LVC will damage the battery.

Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Charge your Li-Po battery to about half capacity before storage. During storage, make sure the battery charge does not fall below 3V per cell.

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.

SAFE Select Flying Tips

When flying in SAFE Select mode the aircraft will return to level flight any time the aileron and elevator controls are at neutral. Applying aileron or elevator control will cause the airplane to bank, climb or dive. The amount the stick is moved will determine the attitude the airplane flies. Holding full control will push the aircraft to the pre-determined bank and roll limits, but it will not go past those angles.

When flying with SAFE Select, it is normal to hold the control stick deflected with moderate aileron input when flying through a turn. To fly smoothly with SAFE Select, avoid making frequent control changes and don’t attempt to correct for minor deviations. Holding deliberate control inputs will command the aircraft to fly at a specific angle, and the model will make all corrections to maintain that flight attitude. When flying with SAFE Select, throttle will make the aircraft climb or descend. Full throttle will cause the aircraft to pitch up and climb slightly. Mid throttle will keep the airplane flying level. Low throttle will cause the airplane to descend slightly nose- down.

Return the elevator and aileron controls to neutral before switching from SAFE Select mode to AS3X mode. If you do not neutralize controls when switching into AS3X mode, the control inputs used for SAFE Select mode will be excessive for AS3X mode and the aircraft will react immediately.

Differences between SAFE Select and AS3X modes

This section is generally accurate but does not take into account flight speed, battery charge status, and other limiting factors.

| SAFE Select|

AS3X

---|---|---
Control Input| Control stick is neutralized| Aircraft will self level| Aircraft will continue to fly at its present attitude
Holding a small amount of control| Aircraft will bank or pitch to a moderate angle and maintain the attitude| Aircraft will continue to pitch or roll slowly

Holding full control

| Aircraft will bank or pitch to the predetermined limits and maintain the attitude| Aircraft will continue to roll or pitch rapidly

Throttle

| Full throttle: Climb Neutral: Level flight
Low throttle: Descend nose-down| Throttle will not affect flight response.

Motor Service

Disassembly

CAUTION: DO NOT handle the rotor or motor while the flight battery is connected. Personal injury could result.

1. In order to access the motor connector(s) it is necessary to separate the top and bottom of the fuselage to access the receiver/ESC. The top and bottom fuselage parts are secured with glue and clear tape. Carefully cut the clear tape and follow the seam with a knife to cut the glue and remove the bottom of the fuselage.
   
   NOTICE: Removing tape or decals can damage paint on your aircraft. Avoid pinching or otherwise damaging any wires when opening or closing the fuselage.

2. Disconnect the motor(s) from the receiver.

3. The fan may be accessed at any time for service by removing the two screws securing it to the front of the motor.

4. The motor may be removed by accessing the rear of the fan assembly through the back of the fan unit. You do not need to separate the nacelle in order to service the motor.
   

Assembly

• Assemble in reverse order, connecting the top and bottom half of the fuselage with clear tape and/or foam safe CA.
