General Binding Tips and Failsafe

• The included receiver has been specifically programmed for 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 red 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

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 in AS3X, in SAFE mode high rates are recommended.

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 exponential 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.

SAFE® Select Technology

The UMX WACO has two flight modes controlled by Channel 5, SAFE and AS3X. Switch A is the Spektrum default for channel 5. Position 0 is SAFE, Position 1 is AS3X only.

When flying in SAFE 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 predetermined bank and pitch limits, but it will not go past those angles.

When flying in SAFE mode, it is normal to hold the control stick deflected with moderate aileron input when flying through a turn. To fly smoothly with SAFE, 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.

Return the elevator and aileron controls to neutral before switching from SAFE mode to AS3X mode. If you do not neutralize controls when switching into 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 take into account flight speed, battery charge status, and other limiting factors.

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 propeller, 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 to disable or enable SAFE Select. The aircraft will cycle both ailerons up and down to indicate a change has been made.

DXe and DXS Transmitters

Switch A is the FMODE switch on these transmitters, and the switch needs to be toggled between position 0 and 2 when disabling/enabling SAFE Select.

Transmitter Switch Diagram Description

Illustrations show transmitter switch operations. For DXe/DXS transmitters, Switch A functions as the FMODE switch, toggled between positions 0 and 2. For other transmitters (Mode 1 and 2), a diagram indicates a repeated action on a switch, labeled 'x 5', suggesting a sequence of five toggles.

ESC/Receiver Arming and Battery Installation

CAUTION: Always keep 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 subsequent connection of a flight battery requires the following steps.

AS3X Initialization

The AS3X® system will not activate until the throttle stick or trim is increased above 25% 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.

Battery Installation Steps

1. Open the battery hatch by lifting from the front.
2. Attach the battery to the hook and loop strip so the battery is centered in the battery cavity.
3. Lower the throttle and power on your transmitter. Enable throttle cut switch.
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 series of tones and a continuous LED (LED may be difficult to see as it is located inside of aircraft) indicates a successful connection.

A solid blue LED indicates that the aircraft is in SAFE flight mode, and a solid RED LED indicates that the aircraft is in AS3X flight mode. When the aircraft is in SAFE, the servos will move without increasing throttle above 25%.

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.

Battery Installation Diagram Description

The steps are illustrated: 1. Shows opening the battery hatch. 2. Shows attaching the battery to the hook and loop strip. 3. Shows powering on the transmitter with throttle low. 4. Shows connecting the battery and a timer graphic indicating 1-5 seconds for initialization.

Center of Gravity (CG)

The CG location is 38mm ± 8mm behind the leading edge of the top wing. This CG location has been determined with the recommended battery. Check the CG with the model upright. Adjust the battery forward or aft so the model balances level at the recommended point.

CG Diagram Description

A diagram shows the top wing of the aircraft with a measurement line indicating '38mm from leading edge of top wing +/-8mm' to denote the CG location.

Control Direction Test

WARNING: Do not perform this or any other equipment test without turning on throttle cut. Serious injury or property damage could result from the motor starting inadvertently.

If the control surfaces do not respond as shown, DO NOT FLY. Refer to the Troubleshooting Guide for more information. If you need more assistance, contact the appropriate Horizon Hobby Product Support department.

Test Procedure

1. Power on the transmitter.
2. Enable the throttle cut.
3. Connect the battery.
4. Use the transmitter to operate the aileron, elevator, and rudder controls.

NOTICE: View the aircraft from the rear when checking the control directions.

Control Surface Responses

• Elevators: Pulling the elevator stick back moves the elevator up, causing the aircraft to pitch up. Pushing the elevator stick forward moves the elevator down, causing the aircraft to pitch down.
• Ailerons: Moving the aileron stick to the left moves the left ailerons up and the right aileron down, causing the aircraft to bank left. Moving the aileron stick to the right moves the right ailerons up and the left ailerons down, causing the aircraft to bank right.
• Rudder: Moving the rudder stick to the left moves the rudder to the left, causing the aircraft to yaw left. Moving the rudder stick to the right moves the rudder to the right, causing the aircraft to yaw right.

Control Direction Diagram Description

A diagram shows three sections for Elevator, Aileron, and Rudder. Each section depicts the transmitter command (stick movement) and the corresponding control surface response (viewed from the rear of the aircraft), illustrating the correct movement for each control.

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 centered. The transmitter sub-trim must always be set to zero.
2. When needed, use a pair of pliers to carefully bend the metal linkage.
3. Make the U-shape narrower to make the linkage shorter. Make the U-shape wider to make the linkage longer.

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.

Centering Controls Diagram Description

An illustration shows how to adjust the control linkage by bending the metal rod to achieve proper centering of control surfaces.

Hand Launching

NOTICE: Hand Launching in AS3X mode is not recommended as it may result in a crash. Always hand launch in SAFE Mode.

Always hand launch in SAFE mode, into the wind at 100% power, in high rates. When hand launching in SAFE mode, the control unit will immediately sense the force of the launch and will automatically enable the Hand Launch Assist feature. When this feature is active, the control unit will add up elevator automatically so the aircraft climbs at a higher angle for a few seconds. It will return to standard SAFE mode shortly after launch.

Grip

We recommend holding the aircraft just behind the wings, as shown.

Follow Through

Use an overhand throw and launch with wings level and the nose of the model slightly upwards. Follow through with your hand launch by pointing your fingers at the airplane after the throw. Avoid an arcing throw which can pull the nose down at release.

Post Flight Checklist

• Disconnect the flight battery from the ESC. (Required for safety and battery life.)
• Power OFF the transmitter.
• Remove the flight battery from the aircraft.
• Store the flight battery apart from the aircraft and monitor the battery charge.
