IMPORTANT: After setting up your model, always re-bind the transmitter and receiver to set the desired failsafe positions. If your transmitter supports it, activate the throttle fail-safe. Always arm the throttle before approaching the aircraft.

IMPORTANT: The Ultrix does NOT require Elevon mixing. Elevon mixing is handled in the receiver.

Dual Rates: Flight modes and Dual Rate / Expo should be on the same switch. A low rate is recommended for the first flights.

NOTICE: To ensure AS3X® technology functions properly, do not lower the frequency below 50%.

Expo: After your initial flights, you can adjust the expo value to better suit your flying style.

Control for Optional Lights: The optional LEDs are controlled by Channel 6. In the channel input menu, set Channel 6 (Aux1) to a momentary switch (I). In the servo setup menu, reverse Channel 6 (Aux1). The LEDs will change to the next light pattern with each change of Channel 6.

Computer-Assisted Transmitter Configuration

Start any transmitter programming with a blank ACRO model (reset model), then name the model.

If Channel 5 and Rates / Expo are assigned to the same switch, there are three flight modes:

• (Pos 0) SAFE
• (Pos 1) AS3X Low Rate
• (Pos 2) AS3X High Rate

Binding Transmitter and Receiver

Binding Procedure

1. Refer to your transmitter's operating manual for instructions on binding the transmitter to a receiver.
2. Ensure the flight battery is not connected to the aircraft.
3. Depending on your transmitter, turn the transmitter off or ensure the RF signal is turned off.
4. Connect the flight battery to the aircraft. The LEDs will begin to flash rapidly, and the LED will flash blue and red, indicating the receiver is in bind mode.
5. Ensure the transmitter control is at idle and the throttle and throttle trim are in the lowest position.
6. Put the transmitter into bind mode. Refer to your transmitter's manual for binding instructions.
7. After 5-10 seconds, the receiver will bind, and the motor will arm. If you encounter problems, refer to the troubleshooting guide in the back of the manual.

For subsequent flights, turn on the transmitter for 5 seconds before connecting the flight battery.

LED Indicator on Receiver

ESC Activation

ESC activation occurs after binding, as previously described, but connecting the flight battery afterwards requires the following steps:

1. Lower throttle and throttle trim to the lowest setting.
2. Turn on the transmitter and wait 5 seconds.
3. Insert the fully charged flight battery and connect it to the aircraft. Slide the battery into the nose.
4. Hold the aircraft still and upright, and keep it out of the wind for five seconds.

Low Voltage Cutoff (LVC)

If a Li-Po cell is discharged below 3 volts, it can no longer hold a charge. The aircraft's ESC protects the battery from deep discharge with Low Voltage Cutoff (LVC). Before the voltage becomes too low, LVC reduces voltage to the motor. The motor will begin to pulse, indicating that there is still enough battery power for a safe approach and landing.

When the motor pulses, land the aircraft immediately and recharge the flight battery.

After flying, ALWAYS disconnect the Li-Po battery from the aircraft to prevent gradual discharge. Fully charge the Li-Po battery and store it properly. During storage, ensure the battery voltage does not drop below 3V per cell.

Tip: Due to the motor's low noise level, you might not hear the pulsing. Therefore, for your first flights, set your stopwatch or timer for 3 minutes. After the first flights, adjust the timer for longer or shorter durations. With controlled throttle management, flight times of 4 minutes are possible. With good throttle management, flight times of 4 minutes or more are possible.

NOTICE: Repeatedly flying until LVC will damage the battery.

Control Surface Centering

Before the first flights or in case of a crash, ensure that the flight control surfaces are centered. Mechanically adjust the linkages if the control surfaces are not centered. When using transmitter sub-trims, the aircraft's control surfaces may not be correctly centered due to the mechanical limitations of linear servos.

1. Ensure AS3X is turned off.
2. Ensure the control surfaces are in the neutral position when the transmitter controls and trims are centered. Transmitter sub-trims must always be in the neutral position.
3. If necessary, adjust linkages. Rotate the ball joint on the linkage to change the length between the servo arm and the control horn until the aileron/elevator is straight.

Centering Controls After Initial Flights

For best AS3X system performance, it is important to avoid large trim adjustments. Do not trim the aircraft while SAFE Select is active. Always trim the aircraft in AS3X mode. If the model requires large trim adjustments (4 or more clicks on the trim), make these mechanical adjustments and return the transmitter trim to the neutral position.

Control Direction Test

Before performing these tests, bind the aircraft and transmitter. Turn on the transmitter and connect the battery. Use the transmitter to control the aileron and elevator controls. When checking control directions, view the aircraft from behind.

• Ailerons:
• 1. Move the aileron stick left. The right aileron should move down, and the left aileron should move up, causing the aircraft to bank left in flight.
• 2. Move the aileron stick right. The right aileron should move up, and the left aileron should move down, causing the aircraft to bank right in flight.
• Elevator:
• 3. Pull the elevator stick back. The elevators should move up, causing the aircraft to climb in flight.
• 4. Push the elevator stick forward. The elevators should move down, causing the aircraft to descend in flight.
• Rudder/Differential Thrust:
• 5. Pull the elevator stick back. The elevators should move up, causing the aircraft to climb in flight.
• 6. Push the elevator stick forward. The elevators should move down, causing the aircraft to descend in flight.

Tip: If the throttle stick is in the OFF position, the motors will not accelerate with rudder input.

Diagram: Illustrations showing correct control surface movements for ailerons, elevator, and rudder in response to stick inputs.

Smart Technology Telemetry

This aircraft is equipped with Spektrum Smart Technology in the receiver, which can provide telemetry information such as battery voltage. To use Smart Technology, you need a compatible transmitter. A firmware update for your transmitter may be required.

To View Smart Telemetry:

1. Start with the transmitter bound to the receiver.
2. Turn on the transmitter.
3. Turn on the aircraft.
4. The Smart logo will appear under the battery icon on the home screen. A signal strength bar will be displayed in the upper left corner of the screen.
5. Scroll past the servo monitor to view the Smart Technology screens.

SAFE® Technology

The Ultrix features two flight modes on Channel 5: SAFE and AS3X. When the aircraft is flying in SAFE mode, it will return to level flight when the aileron and elevator controls are at neutral. Using the aileron or elevator controls can cause the aircraft to bank, climb, or enter a dive. The intensity with which the control stick is moved determines the aircraft's attitude. Maintaining full control challenges the aircraft's preset pitch and bank limits but does not cause it to exceed these angles. When flying with SAFE, the control stick is typically held in the deflected position, with moderate input used for turns. To fly smoothly with SAFE, avoid frequent control changes and try to minimize correcting minor deviations. Deliberate control inputs command the aircraft to fly at a specific angle, and the model makes all adjustments to maintain that attitude. Set the elevator and aileron controls to neutral, then switch from SAFE mode to AS3X mode. If the controls are not neutralized when switching to AS3X mode, the control inputs used for SAFE mode are too large, 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 state, and other limiting factors.

Tips for Flying and Repairs

WARNING: If your transmitter supports it, always arm the throttle before approaching the aircraft.

Radio System Range Check

Perform a range check after final assembly. Refer to your transmitter's manual for instructions.

Flying

It is recommended to fly your Ultrix outdoors only in moderate wind conditions or in large indoor facilities. Avoid flying near houses, trees, power lines, and buildings. You should also avoid flying in areas with many people, such as busy parks, schoolyards, or football fields. Please observe local regulations and laws before choosing a place to fly.

Hand Launch

To hand launch the aircraft, grip the wing from behind between the tail fins with your thumb on top. It is recommended to start in SAFE flight mode. Move the throttle stick to full throttle and gently and lightly throw the aircraft forward into the wind (5-10 degrees above the horizon). After the model gains altitude and speed, reduce throttle as desired.

Takeoff

Roll the model into takeoff position (outdoors, facing into the wind). Gradually increase throttle to full, holding slight up-elevator. Use rudder to maintain the takeoff direction. Climb and check trim. Do not trim the aircraft while SAFE Select is active. Always trim the aircraft in AS3X mode. Once trimmed, you can begin to explore the model's performance.

Landing

Always land into the wind. During the approach, keep the wings level and the aircraft into the wind. Gradually reduce throttle and simultaneously ease back on the elevator to land the aircraft on its belly.

TIP: Belly landings on soft ground are recommended. If landing on hard surfaces is the only option, consider installing the optional nose skid.

NOTICE: To avoid damage to propellers and motors, always reduce throttle completely when the aircraft touches the ground during landing. If the throttle stick and trim are not set to the lowest possible positions during a crash, damage to the receiver's ESC may occur.

Post-Flight Checklist

1. Disconnect the flight battery from the ESC.
2. Turn off the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace any damaged parts.
6. Store the flight battery separately from the aircraft and monitor its charge.
7. Record flight conditions and flight plan results to plan future flights.

Maintenance and Repairs

Crash damage is not covered by the warranty. Perform repairs with foam-compatible CA glue or clear tape, as other types of adhesives can damage the foam. If parts are not repairable, please refer to the parts list for the part number. A list of all replacement and optional parts is on the back of the instruction manual.

Disassembly

CAUTION: DO NOT handle the motor while the flight battery is connected. This could cause injury.
