Transmitter and Receiver Binding

Binding Procedure
1. Refer to your transmitter manual for instruction on binding the transmitter to a receiver.
2. Ensure the flight battery is not corrected to the aircraft.
3. Depending on your transmitter, either power off the transmitter or ensure the RF signal is off.
4. Connect the flight battery to the Aircraft. The LEDs will begin flashing fast, the LED will flashing blue and red indicating the receiver is in the binding mode.
5. Make sure the transmitter controls are at neutral and the throttle and throttle trim are ii the low position.
6. Place the transmitter in bind mode. Refer to your transmitter manual for tindrig instructions.
7. After 5-10 seconds. the receiver will connect and the motor will arm. if you encounter problems refer to the Troubleshooting Guide at the bad( of the manual.

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

Low Voltage Cutoff Red Flashing

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

Arming the ESC

  1. Lower throttle and throttle trim to lowest settings. Power on the transmitter then wait 5 seconds
    HORIZON E-file Ultrix 600mm - Arming the ESC 1
  2. Install the flight battery and connect it to the ESC.  Slide battery to nose

  3. Keep the plane immobile,  upright, and away from the wind for 5 seconds. A series of tones indicates the aircraft is armed and ready.
    HORIZON E-file Ultrix 600mm - Arming the ESC 3

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). Before the battery charge decreases too much, LVC removes power supplied to the motor. Power to the motor quickly decreases and increases, showing that some battery power is reserved for flight control and safe landing.
When the motor power pulses, land the aircraft immediately and recharge the flight battery. Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. During storage, make sure the battery charge does not fall below 3V per cell.
TIP: Due to the quiet nature of the aircraft, you may not hear the pulsing of the motor.
For your first flights, set your transmitter timer or a stopwatch to 3 minutes. Adjust your timer for longer or shorter flights once you have flown the aircraft. Flights of 4 minutes or more are achievable if using proper throttle management.
NOTICE: Repeated flying to LVC will damage the battery.

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. The use of the transmitter sub-trims may not correctly center the aircraft control surfaces due to the mechanical limits of linear servos.

HORIZON E-file Ultrix 600mm - Control Centering

  1. Ensure AS3X 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, adjust the linkage. Turn the ball link on the linkage to change the length between the servo arm and the control horn until the elevon is straight.

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.

Control Direction Test

Properly bind your aircraft and transmitter before doing these tests. Verify the linkages move freely. Switch ON the transmitter and connect the battery. Use the transmitter to operate the aileron and elevator controls. View the aircraft from the rear when checking the control directions.
HORIZON E-file Ultrix 600mm -Control Direction TestAilerons

  1. Move the aileron stick to the left. The right elevon should move down and the left elevon up, which will cause the aircraft to bank left in flight.
  2. Move the aileron stick to the right. The right elevon should move up and the left elevon down, which will cause the aircraft to bank right in flight.
  3. Pull the elevator stick back. The elevons should move up, which will cause the aircraft to pitch up in flight.
  4. Push the elevator stick forward. The elevons should move down, which will cause the aircraft to pitch down in flight.
    Rudder/ Differential Thrust
  5. Move the rudder stick to the left. The right motor will accelerate, which will cause the aircraft to yaw left in flight.
  6. Move the rudder stick to the right. The left motor will accelerate, which will cause the aircraft to yaw right in flight.
    Tip: The motors will not accelerate with rudder input when the throttle is in the OFF position.

Smart Technology Telemetry

This aircraft includes Spektrum Smart Technology in the receiver, which can provide telemetry information like battery voltage. To take advantage of Smart Technology, you will need a compatible transmitter. A firmware update for your transmitter may be required.
To View Smart Telemetry:

  1. Begin with the transmitter bound to the receiver
  2. Power on the transmitter.
  3. Power on the aircraft.
  4. The Smart Logo appears under the battery logo on the home page. A signal bar appears in the top left corner of the screen.
  5. Scroll past the servo monitor to view Smart technology screens.

For more information about compatible transmitters, firmware updates, and how to use the Smart Technology on your transmitter, visit www.SpektrumRC.com.

SAFE® Technology

The Ultrix has two flight modes on Channel 5, SAFE and AS3X.
When flying in SAFE mode, the aircraft will return to level flight any time the aileron and elevator controls are neutral. Applying aileron or elevator control will cause the airplane to the 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 a SAFE  ode, 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.

SAFE Select AS3X
Control Input The 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

Flying Tips and Repairs

WARNING: If your transmitter supports it, always engage throttle cut before approaching the aircraft. 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.
We recommend flying your aircraft outside in no greater than moderate winds or inside in a large gymnasium. 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.

HORIZON E-file Ultrix 600mm - Flying

Hand Launching
To hand launch the aircraft, pinch the wing from the rear between the vertical stabilizers with your thumb on top. We recommend launching in SAFE flight mode. Advance to full throttle and release the aircraft with a gentle forward toss, slightly up (5–10 degrees above the horizon), and directly into the wind. After the model gains altitude and speed, decrease the throttle as you desire.
Always land into the wind. During the flare, keep the wings level and the aircraft pointed into the wind. Slowly lower the throttle while easing back on the elevator to bring the aircraft gently down for a belly landing.
TIP: We recommend belly landings on a soft surface. If hard surfaces are your only option for landings, consider installing the optional nose skid.
NOTICE: Always fully lower the throttle at the touch down when landing the aircraft to prevent damage to the propellers and motors.
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.
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.
Crash damage is not covered under warranty.
Repair this aircraft using foam-compatible CA glue or clear ape. Only use foam-compatible CA glue as other types of glue can damage the foam. When parts are not repairable,
see the Replacement Parts List for ordering by item number.
