Explanation of DXe Transmitter LEDs, Switches and Modes for the Apprentice.

Trainer/Bind/Panic Switch (B):

This switch is used as both the trainer and bind switch as well as the Panic Switch for your Apprentice STS. For complete binding instructions, refer to the binding section below. When using the trainer function, connect the trainer cord (SPM6805) into the trainer port in both the master (instructor) and the slave (student) transmitters. The master transmitter must be powered ON and bound to the receiver. The slave transmitter must be powered OFF. Any time you press and hold the trainer button on the master, it will give control authority to the slave. Releasing the trainer button returns control to the master.

IMPORTANT: The slave transmitter must always have the same settings as the master. See Flight Training section for setup of other Spektrum Transmitters.

Hi/Lo Rate Switch (J ):

This switch supports high and low rate functions on aileron, elevator and rudder channels. In the upper, or “HI” position, servo travel is 100% on these channels. In the lower, or “LO,” position, servo travel decreases to 70%. This switch lets you quickly

change control rates from high for aggressive maneuvers to low for smooth, precise maneuvers. When learning to ﬂ y, use low rate.

Channel 5 Switch (C):

This switch is used to select the SAFE Flight mode. For other conventional receivers, this switch controls a servo connected to the Channel 5/Gear port.

LEDs (D) show: Flashing with beeps Bind mode when Trainer (Bind) switch is held and the

transmitter is powered on (see Binding instructions).

Pulsates with one low tone beep every 2 seconds (when transmitter battery voltage drops below 4.7 volts). Replace the batteries immediately. If this happens while ﬂ ying, land your aircraft as soon and as safely as possible.

WARNING: Before proceeding further, remove the propeller and spinner from the motor shaft. Never attempt

to program the radio components, assemble the aircraft or perform maintenance of any kind without removing the propeller or engaging throttle cut. Serious injury could result if the motor starts inadvertently with the propeller still attached.

1. Remove the spinner (A) from the backplate (B), by pinching the backplate and pulling the spinner away.

2. Remove the hex nut (C), washer (D) and propeller (E) from the collet (F). A 10mm wrench may be required to remove the hex nut.

Transmitter Setup (BNF)

If using any DSMX transmitter other than the included DXe (3 position gear switch, RTF only) the radio will have to be conﬁ gured correctly for the SAFE system to work properly.

• SAFE Flight mode is selected using Channel 5 signal (high, middle, low)

• Panic mode is selected with Channel 6 signal (high, low)

Refer to your transmitter’s manual for more information about transmitter setup.

If using a 2 position switch for SAFE ﬂ ight modes, only Beginner and Experienced modes will be active.

Any DXe Transmitter that was not included with a EFL Apprentice STS RTF will need to be programmed using the Spektrum Programmer (SPMA3065) to function correctly with this aircraft. Visit www.spektrumrc.com to download the correct program for this aircraft.

BNF Transmitter Telemetry Setup

If the transmitter that you intend to use with this aircraft is not displaying telemetry data, visit Spektrumrc.com and update your ﬁ rmware. With the latest ﬁ rmware installed on your transmitter the telemetry option should now be functional on your transmitter.

Transmitter and Receiver Binding

Binding is the process of programming the control unit to recognize the GUID (Globally Unique Identiﬁ er) code of a single speciﬁ c transmitter.

The aircraft should be bound to the transmitter at the factory, but if you need to re-bind them, follow these steps. If your aircraft does not respond to the transmitter when the batteries in the aircraft and transmitter are fully charged, your aircraft and transmitter may need to be re-bound using the instructions below.

Please refer to the optional parts list in this manual or visit www.bindnﬂ y.com for a list of compatible transmitters. For the BNF aircraft, you need to ‘bind’ your chosen Spektrum™ DSMX proper operation.

IMPORTANT: The throttle will not arm if the transmitter’s throttle control is not put at the lowest position. If you encounter problems, follow the binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the appropriate Horizon Product Support ofﬁ ce.

technology equipped aircraft transmitter to the receiver for

Binding Procedure (without GPS Module)



1. Make sure the transmitter is powered off.

2. Make sure the transmitter controls are neutral, the throttle is in the low position, and the aircraft is immobile.

3. Connect the ﬂ ight battery in the aircraft, then power on the ESC switch. The Flight Controller LED will begin to ﬂ ash red and blue.

4. On the remote Spektrum receiver that is connected to the ﬂ ight controller, press and release the bind button. The receiver LED will ﬂ ash rapidly.

5. Press and hold the trainer button on the top of the transmitter while turning on the power switch.

6. When the receiver binds to the transmitter, the receiver LED will be solid on. Flight controller LED in windshield will also be green when in beginner mode. (without LAS or GPS installed)

Once bound the receiver and transmitter should retain their bind for future ﬂ ights.

Applies only when the optional GPS module is installed

IMPORTANT: IF THE OPTIONAL GPS MODULE IS INSTALLED the aircraft will not respond to transmitter commands after binding if it cannot acquire a GPS

signal.

Binding: After binding with the GPS module installed, the aircraft will search for a GPS lock, indicated by the elevator slowly cycling up and down. After acquiring a GPS lock, all ﬂ ight controls will respond normally except throttle. The throttle will be limited, allowing the aircraft to be taxied out to takeoff position on the runway. Set the home position to regain full functioning throttle. See the Powering On With GPS section of this manual for further details.

Compass calibration: After binding the ﬁ rst time with the GPS module installed in the aircraft, compass calibration is required. The aircraft will automatically enter the compass calibration sequence after installing the GPS for the ﬁ rst time. This is indicated by the ailerons slowly cycling up and down. The aircraft will not respond to transmitter commands with the GPS module installed until calibration has been completed. See the Compass Calibration section of this manual for further details.

Subsequent binding with the GPS module will not require compass calibration.

Flight Battery Installation, SAFE system and Electronic Speed Control (ESC) Arming

1. Rest the aircraft on a ﬂ at surface with the landing gear facing up and make sure the switch is OFF.

2. Turn the latch (A) and open the battery hatch.

3. Lower the throttle and turn on the throttle hold switch, then power on the transmitter for at least 5 seconds.

4. Connect the ﬂ ight battery to the aircraft.

5. Secure the ﬂ ight battery (B) in the battery compartment using the hook and loop straps (C) so that the aircraft has a balanced Center of Gravity (CG).

TIP: Connect the battery to the ﬂ ight controller plug before securing the battery. Tuck the battery wires through the opening in the battery compartment. Then secure the battery with the hook and loop straps.

Important: Before ﬂ ying, refer to the “Verifying Your Aircraft’s Center of Gravity (CG)” section for details about ﬁ nal battery placement.

6. Close the battery hatch and turn the latch to secure the hatch shut.

Mode 2 Mode 1

7. Put the aircraft on its landing gear, then power ON the Switch (D). The aircraft should be on level ground and must be kept immobile while the SAFE system initializes. If the aircraft does not initialize after about 30 seconds because of too much movement, power OFF the ESC Switch and power it on again to reinitialize the system.

After the SAFE system initializes, the rudder will move back and forth, then come to neutral to indicate the SAFE system has initialized and is ready to operate. If you accidentally connect the battery while the throttle is not a its lowest position, the ESC will not arm the motor. Reduce throttle to lowest setting for motor to arm.

IMPORTANT: SAFE technology is not active until you advance the throttle past 25%. Once it is active, the control surfaces may move on the aircraft. This is normal. The SAFE technology will remain active until the ESC is turned off.

CAUTION: Always disconnect the Li-Po ﬂ ight battery from the aircraft

receiver when not ﬂ ying 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 ﬁ re when batteries are charged.

CAUTION: Always keep hands away from the propeller. When armed, the

motor will turn the propeller in response to any throttle movement.

Center of Gravity (CG)

An aircraft with a correct CG has its weight balanced at a calculated point where the entire airframe will balance when suspended at that point. After installing the battery (in the recommended position) and before powering on the ESC switch, verify the CG by supporting the aircraft 79.0mm (approximately 3.125 inches) back from the front edge of the wing, as shown.

Keep immobile and

out of the wind for

5 seconds

Balance the aircraft on your ﬁ ngertips near the fuselage under the wings.

• If the nose goes down, move the ﬂ ight battery back until the aircraft balances.

• If the nose goes up, move the ﬂ ight battery forward until the aircraft balances.

When ﬂ ying with correct CG in beginner mode, the aircraft should climb gradually at full power and ﬂ y level at 50%–60% power with no elevator input. If the aircraft CG is too far forward (nose heavy), up elevator is required to ﬂ y level at 50%–60% power. If the aircraft CG is too far aft (tail heavy), down elevator is required to ﬂ y level. Adjust the battery position as needed.

Control Direction Test

WARNING: Do not perform this or any other equipment test with the

propeller installed on the aircraft. Serious injury or property damage

could result from the motor starting inadvertently.

1. Set the ﬂ ight mode switch to Experienced mode (position 2).

2. Keep the throttle at zero and place the model on level ground away from obstacles.

3. Move the sticks on the transmitter as described in the table to ensure the aircraft control surfaces respond as shown.

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.

If the aircraft responds as shown, continue on to the Flight Control section.

Choose a Flying Field

Consult local laws and ordinances before choosing a location to ﬂ y your aircraft.

In order to have the most success and to protect your property and aircraft, it is very important to select a place to ﬂ y that is very open.

Remember, your aircraft can reach signiﬁ cant speeds when ﬂ ying and can cover ground quickly. Plan on ﬂ ying in an area that gives you more space than you think you need, especially with ﬁ rst ﬂ ights.

The ﬂ ying site should:

• Have a minimum of approximately 1300 feet (400m) of clear space in all directions.

• Be clear of people and pets.

• Be free of trees, buildings, cars, power lines or anything that could entangle your aircraft or interfere with your line of sight.

Range Test

WARNING: Do not perform this or any other equipment test with the

propeller installed on the aircraft. Serious injury or property damage could result from the motor starting inadvertently.

WARNING: While holding the aircraft during the range test, always keep body parts and loose items away from the motor. Failure to do so could cause personal injury.

Before each ﬂ ying session, and especially with a new model, you should perform a range check. If you have the BNF aircraft, refer to your transmitter manual to perform a range check of your system.

The RTF included DXe transmitter incorporates a range check mode to reduce the output power of the transmitter. Follow the directions below to enter range check mode for the DXe transmitter:

1. Power on the transmitter for 5 seconds or more with the throttle stick and trim low. Plug in the aircraft battery and keep the aircraft immobile for 5seconds.

2. Face the model with the transmitter in your normal ﬂ ying position.

3. Toggle (back and forth = 1 toggle) the HI/LO Rate switch rapidly 4 times and then press and hold the bind button. The transmitter LEDs will ﬂ ash and the alarm will sound. The system is in range check mode. Do not let go of the bind button until you are ﬁ nished with the range check.

IMPORTANT: You must hold the BIND/Panic button during the entire range check

process. Releasing the button will exit the range check mode.

4. With the radio system powered on and the model restrained on the ground, stand 28meters (90 feet) away from the model.

TIP: In some aircraft, when the model is placed on the ground, the antenna(s) can be within inches of the ground. Close proximity of the antenna(s) to the ground can reduce the effectiveness of the range check. If you experience issues during the range check, restrain the model on a non-conductive stand or table up to 2ft (60cm) above the ground, then range check the system again.

5. Move the transmitter rudder, elevator, aileron and throttle controls to ensure they operate smoothly at 28 meters (90 feet).

6. If control issues exist, do not attempt to ﬂ y. Refer to the contact table at the end of the this manual to contact Horizon Hobby product support. Also, see the Spektrum website for more information.

7. When the range check is successfully completed, release the bind button to exit range check mode.

CAUTION: Due to reduced output power of the transmitter, NEVER attempt to ﬂ y while the transmitter is in range check mode. Loss of control will occur.

WARNING: Do not install the propeller until the aircraft has been

completely assembled, all the systems have been checked thoroughly and you are located at a suitable ﬂ ying site.

Follow the instructions below to install the propeller and spinner.

1. Install the propeller (E), backplate (B),washer (D), and hex nut (C) onto the motor shaft.

2. Thighten the hex nut with a 10mm wrench to secure the propeller into place.

3. Push the spinner (A) onto the backplate until it clicks.

IMPORTANT: The motor shaft and prop nut are reverse-threaded. Turn the prop nut counter-clockwise to tighten it to the motor shaft.

SMART Technology Electronic Speed Control (ESC)

The Apprentice STS is equipped with an exclusive Smart ESC that can provide a variety of real-time power system related telemetry data including motor RPM, current, battery voltage and more to compatible Spektrum AirWare™ equipped transmitters (including the DX6e and 8e, DX6 and 8 G2, the DX9, iX12 and others) while you ﬂ y.

Access the telemetry data by plugging the ESC into channel 6 on the A3230 Flight Controller. The ESC will send the below information to the ﬂ ight control and the information will be displayed on the compatible transmitter.

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 ﬂ ight battery.

NOTICE: Repeated ﬂ ying 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.

Sensor Assisted Flight Envelope (SAFE) Technology Flight Modes

At any time during a ﬂ ight you can switch between the 3ﬂ ight modes or use Panic recovery to get your aircraft to a safe ﬂ ying attitude. Change between ﬂ ight modes by changing the ﬂ ight mode switch position.

Beginner Mode (position 0) Green LED on Aircraft

• Envelope limit: Pitch (nose up and down) and Roll (wing tips up and

down) angles are limited to help you keep the aircraft airborne.

• Self-leveling: when the pitch and roll controls are returned

to neutral, the aircraft returns to level ﬂ ight.

• Stability assisted takeoff and landing.

• Throttle based climb and descent.

Intermediate Mode (position 1) Blue LED on Aircraft

• Natural Flight Experience: In normal training ﬂ ight conditions, the pilot

experiences natural AS3X

• Large Flight Envelope: The pilot is only prevented from entering

extreme ﬂ ight conditions outside the training ﬂ ight envelope.

TIP: When ﬂ ying Intermediate Mode, the Apprentice STS will automatically be in beginner mode when below 100 feet. The Blue LED will still be shown.

• Unlimited Flight Envelope: No limit on Pitch and Roll angles (airframe limited).

Panic Recovery

This function is intended to provide you with the conﬁ dence to continue to improve your ﬂ ight skills. If you become disoriented or the aircraft is in an unknown or uncomfortable attitude in any ﬂ ight mode:

1. Press and hold the Bind/PANIC button on the transmitter and release the control sticks. The aircraft will immediately pull out of a dive and roll wings upright and level.

IMPORTANT: The aircraft will recover to a safer attitude even if sticks are held while holding the PANIC button. However, release the control sticks for the quickest recovery.

Flight Control

IMPORTANT: Even though SAFE technology is a very helpful tool, the aircraft

still needs to be ﬂ own manually. If incorrect input is given at lower altitudes or at slower speeds, the aircraft can crash. Study these control inputs and the aircraft response to each carefully before attempting your ﬁ rst ﬂ ight.

For ﬁ rst ﬂ ights, set the SAFE

For smooth control of your aircraft, always make small corrections. All directions are described as if you were sitting in the aircraft.

Flying faster or slower: When your aircraft is stable in the air, push the throttle stick up to make the aircraft go faster. Pull the throttle stick back to slow down. The aircraft will climb when the throttle is increased.

Elevator up and down: Push the elevator stick forward to make the aircraft go down. Pull the elevator stick back to go up.

Aileron right and left: Move the aileron stick right to make the aircraft roll or “bank” right. Move the aileron stick left to bank left.

TIP: Always picture yourself in the aircraft when determining which way to bank the aircraft wings. When the aircraft is ﬂ ying away from you, banking the aircraft right or left appears normal. When ﬂ ying toward you, the aircraft will appear to bank the opposite direction to the control input given. This will become more instinctual with experience.

Rudder left and right: Push the rudder stick left or right to yaw or point the nose of the aircraft left or right. The rudder stick is also used to steer the aircraft left and right while taxiing on the ground.

Flight Training

Instruction

To the new pilot:

This aircraft is easy to ﬂ y and helps you apply beginner skills to ﬂ ying; however, we recommend you get help from a qualiﬁ ed ﬂ ight instructor for your ﬁ rst radio controlled ﬂ ights. Some model ﬂ ying clubs provide ﬂ ight training at their ﬂ ying ﬁ elds. Find a nearby ﬂ ying club through your local hobby shop. In the U.S., visit the Academy of Model Aeronautics at www.modelaircraft.org. for more information on clubs and ﬂ ight instruction.

To the ﬂ ight instructor:

Feel free to experiment with the SAFE technology before instructing your student on this aircraft. The progressive switch positions in the SAFE technology are intended for a new pilot to learn with minimal instructor assistance. We recommend using Channel 5 Switch Position 1 to instruct a new pilot. Switch positions 0 and 2 may stabilize the aircraft more or less than you desire for instruction purposes.

DXe Trainer Feature

Your DXe transmitter may be connected to another transmitter through the trainer ports using a trainer cord (SPM6805, sold separately).

Top

Trainer Button

Trainer port

The DXe transmitter is ideal* as the master as it is compatible with all Spektrum transmitters when using this feature. Servo reversing and trims must be the same on both transmitters.

This “buddy box” approach has helped many new pilots get the feel for aircraft control with the close assistance of a ﬂ ight instructor. Connecting two transmitters enables your ﬂ ight instructor to hold the master transmitter while you hold the slave transmitter. While you learn to ﬂ y, the instructor holds the trainer switch to give you control of the aircraft. If you need help, the ﬂ ight instructor can release the switch to take control.

IMPORTANT: If a transmitter other than the included DXe is used for master or slave, refer to Optional Transmitter Setup in this manual.

* Failsafe (RED LED FAST FLASHING)

If the receiver loses transmitter communication, the failsafe will activate. When activated, failsafe moves the throttle channel to its preset failsafe position (low throttle) that was set during binding. All other channels move for the aircraft to slowly circle and descend until radio link is re-established.

Buddy Box Setup

IMPORTANT: If using the buddy box option for training on a transmitter other than

the included DXe use these settings for a Master and or Slave Transmitter. Failure to do so will not allow SAFE technology Flight modes to work correctly.

IMPORTANT: If using the buddy box option the transmitter must be conﬁ gured using the Transmitter Setup and Buddy Box setup charts.

Ground Launch

Once the aircraft is ready for ﬂ ight, slowly advance the throttle to start the takeoff roll into the wind. Small rudder inputs may be required for heading correction as the aircraft will begin a slow climb out as the throttle is advanced.

TIP: Rudder / nose wheel control throw is automatically set for taxi mode in beginner mode when on the ground and under 6 meters of altitude.

This provides more control to taxi the aircraft and yaw control during landings.

Once airborne, rudder control throw is automatically reduced to beginner ﬂ ight mode.

In Flight

Let the aircraft climb at full throttle, into the wind, until the aircraft gets about 300 feet (91m) above the ground, then decrease the throttle to half (50%).

Make small and gentle stick movements to see how the aircraft responds.

Flying with the nose pointed toward you is one of the hardest things to do when learning to ﬂ y. Practice ﬂ ying in large circles high off the ground.

If you lose orientation of the aircraft, press and hold the PANIC button and the aircraft will return to level ﬂ ight.

NOTICE: If a crash is imminent, activate throttle hold or quickly lower the throttle and throttle trim. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

Wind

Slowly advance

the throttle stick.

When properly trimmed, the aircraft’s wing design causes a climb at full throttle without the use of elevator.

Adjusting Trim in ﬂ ight

If your aircraft does not ﬂ y straight and level at half throttle with the sticks at neutral, ﬂ y into the wind and adjust the trim sliders as indicated in the table until the aircraft maintains a reasonably straight and level ﬂ ight path.

• Trimming is best done in calm wind conditions.

• The SAFE ﬂ ight mode switch should be set to Experienced mode (position2) before adjusting the trims.

After the aircraft is trimmed in ﬂ ight, land the aircraft and proceed to the Manually Adjusting Trim section to set the trim mechanically.

The included RTF DXe transmitter features electronic trim buttons. The transmitter emits a faint beep with each click of the trim buttons in either direction. Holding the button in either direction quickly adjusts the trim several steps until the button is released or until the trim reaches the end of its travel. If the trim button does not beep when clicked, the trim is at the far end of its travel. Center trim is indicated by a slightly louder beep.

TIP: Trim the aircraft at sufﬁ ciant altitude of 30 meters (about 100’). Having an experienced ﬂ ight instructor trim your aircraft during the ﬁ rst ﬂ ight is recommended.

Landing

Land the aircraft manually when GPS is not installed

1. Reduce the throttle to around 50% to slow the airspeed.

2. Fly the aircraft downwind past the end of the runway.

3. Turn the aircraft into the wind and line the aircraft up with the runway center line.

4. Decrease the throttle further and begin descending towards the runway, keeping the wings level during approach. Try to have the aircraft at 10ft altitude as it passes over the threshold of the runway.

5. As the aircraft passes over the threshold of the runway decrease the throttle fully.

6. Just as the aircraft is about to touch down, gently pull back on the elevator to raise the nose and ﬂ are for a gentle landing.

65ft (20m)

Wind

NOTICE: If a crash is imminent, activate throttle hold or quickly lower the throttle. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

IMPORTANT: When ﬁ nished ﬂ ying, never keep the aircraft in the sun. Do not store the aircraft in a hot, enclosed area such as a car. Doing so can damage the foam.

Water Takeoff and Landing Using the Optional Float Set

IMPORTANT: We recommend ﬂ ying with ﬂ oats only once you have become able to

ﬂ y comfortably in Experienced ﬂ ight mode.

Only use the ﬂ oats if you are comfortable ﬂ ying your aircraft and have repeatedly taken off, ﬂ own and landed with success. Flying off water poses a higher risk to the airplane because the electronics can fail if fully immersed in water.

Always ensure the optional ﬂ oats (ELFA550, sold separately) are secure on the fuselage and that the ﬂ oat rudder linkage is correctly connected and moves freely before putting the aircraft in water.

To take off on water, steer with the rudder and slowly increase the throttle. Keep the wings level on takeoff. Hold a small amount (1/4–1/3) of up elevator and the aircraft will lift off once ﬂ ying speed is reached. Avoid rapidly increasing the throttle as torque from the motor may cause the aircraft to roll to the left when on water.

To land this aircraft on water, ﬂ y the aircraft to a couple of feet off the surface of the water. Reduce throttle and add up elevator to ﬂ are the aircraft.

When taxiing, you must use throttle to move the aircraft forward, but steer with the rudder stick. The stick will turn both the aircraft rudder and a small rudder attached to the left ﬂ oat.

CAUTION: Never swim or go alone to get a downed model in the water.

CAUTION: If at any time water splashes in the fuselage while ﬂ ying from

water, bring the airplane to shore, open the battery hatch and immediately remove any water that may have gotten in the fuselage. Leave the battery hatch open overnight to let the inside dry out and to prevent moisture damage to the electronic components. Failure to do so could cause the electronic components to fail, which could result in a crash.

Avoid taxiing cross wind if there is a breeze, as this can cause the aircraft to ﬂ ip over if wind gets under the wing. Taxi 45 degrees into the direction of the wind (not perpendicular to the wind) and use aileron to hold the upwind wing down. The aircraft will naturally try to face into the wind when taxiing.

Always fully dry the aircraft after landing on water.

Post Flight

1 Disconnect the ﬂ ight battery from the ESC (Required for Safety and battery life). 2 Power OFF the transmitter. 3 Remove the ﬂ ight battery from the aircraft. 4 Recharge the ﬂ ight battery.

Optional Landing Assist Sensor (LAS) Upgrade

The Apprentice STS is upgradable with the addition of the optional LAS module (SPMA3180 not included) this allows the advanced SAFE features to be combined with an Landing Assist Sensor (LAS) for smoother gentler landings.

IMPORTANT: For best results when using LAS, land on grass surfaces or a

light colored surface, such as light colored concrete. Black surfaces or water normally do not have enough reﬂ ection for the sensor to receive accurate readings.

Installation of the LAS module

1. Remove the wing to gain access to the ﬂ ight controller compartment.

2. Rotate the aircraft to access the bottom of the fuselage.

3. Press the factory installed plug (A) to release it. Then removed it from

the LAS pocket. Save the plug for ﬂ ights without LAS module.

4. Feed the LAS connector through the channel in the base of the LAS pocket.

5. Align the LAS module with the wires facing the back of the aircraft. Place the LAS module into the pocket and press it to secure it into place with a click.

6. Place the aircraft on its landing gear and connect LAS connector to Channel 7 on the ﬂ ight controller. For correct polarity of the plug ensure that the orange (not brown) signal wire (B) is facing towards the front of the aircraft when plugged into the ﬂ ight controller.

Landing with LAS

Reduce throttle, keep the wings level and slowly reduce the altitude of the aircraft. When the aircraft’s landing approach reaches an altitude of roughly 1m the LAS will level off the aircraft, manage the throttle and then ﬂ are the aircraft for touchdown.

IMPORTANT: LAS is functional for all SAFE ﬂ ight modes except for

Experienced Mode. When the ﬂ ight mode is switched to Experienced mode the LAS is deactivated and the pilot will have zero assistance on landing, a traditional manual landing of the aircraft is necessary.

IMPORTANT: Installation of the LAS module is not auto land. The aircraft must be guided and aligned with the landing strip for landing.

LED indicator

When the LAS module is installed the aircraft’s LED indicator for beginner and intermediate ﬂ ight modes will be followed with a purple ﬂ ash to indicate that the LAS System is active.

LAS with GPS

With GPS installed LAS will assist the Auto Land mode during landing of the aircraft. When the aircraft’s landing approach reaches an altitude of roughly 1m the LAS will level off the aircraft, manage the throttle and then ﬂ are the aircraft for touchdown.

TIP: If the speed of aircraft is too fast for landing or above 20% throttle setting, LAS is not effective.

TIP: If the Aircraft’s landing approach is too low and fast, LAS will not ﬂ are.

The Apprentice STS ﬂ ight controler is upgradable with the addition of the optional SPMA3173 GPS module (not included) which enables advanced SAFE+ features. With SAFE+, the aircraft can ﬂ y a holding pattern on its own, return home and land by itself, and prevent the model from ﬂ ying too far from the pilot.

IMPORTANT: Read the information in this manual covering the optional SAFE+ GPS upgrades, and learn the use of Holding Pattern and Autoland modes before ﬂ ying with GPS. SAFE+ features are only available with the SAFE+ module installed and properly calibrated.

Follow the steps to add SAFE+ functions to your aircraft.



1. Charge the ﬂ ight battery.

2. Set up your transmitter (BNF only).

3. Install the GPS module.*

4. Find a safe and open area.

5. Power the model on outdoors and perform the compass calibration.

6. Unplug the battery after the compass calibration is complete.

7. Power the model on and allow it to acquire a GPS lock. The elevator will move up and down until GPS lock is acquired, and then re-center.

8. Set the home position (and ﬂ ying ﬁ eld location for ﬂ ying ﬁ eld mode). IMPORTANT: Do not ﬂ y at this time.

9. Place the aircraft into Experienced mode (Mode switch position 2) for the control direction test. Place the aircraft on the ground facing away from you.

10. Perform Control Direction Test.

11. Place the aircraft into Beginner mode (Mode switch position 0) and cycle the throttle to activate SAFE.

12. Perform SAFE Control Direction Test.

13. Plan ﬂ ight for ﬂ ying ﬁ eld conditions.

Compass Calibration

Compass calibration might be required after installing the GPS module, before ﬂ ight. The aircraft will automatically enter compass calibration on the ﬁ rst power up after the GPS module is installed, after binding.

IMPORTANT: The aircraft must be outside and needs to acquire a GPS lock in order to begin compass calibration. The aircraft will not enter compass calibration mode until the GPS lock is established.

Perform the compass calibration before the ﬁ rst ﬂ ight or to correct the heading during auto landing if it varies signiﬁ cantly from the heading set during takeoff.

Before calibration GPS lock must be established for your location:

1. Remove the propeller if it is installed or activate throttle cut.

2. Powe ON the transmitter and receiver and set the model on the ground on its wheels. The aircraft’s elevator will slowly move up and down until GPS lock is established. When ﬁ nished the elevator will move up and down once quickly and center.

3. Power OFF the receiver and then the transmitter.

Once initial GPS lock is established Compass Calibration can be performed.

1. With the transmitter trims centered, power ON the transmitter and the aircraft while holding the transmitter sticks as shown. The aircraft will indicate the GPS is searching for satellites by cycling the elevator up and down. Continue to hold the transmitter sticks as shown.

2. After satellites are acquired, the aircraft will signal it has entered compass calibration mode by the following:

-The ailerons will cycle left and right slowly.

-The LED will ﬂ ash red and blue.

3. Once in calibration mode, the throttle is not active and the transmitter sticks can be released. The transmitter must remain powered ON.

4. Flip the aircraft twice nose over tail as shown.

5. Turn the aircraft 90 degrees and roll the aircraft twice, as shown.

6. Turn off the transmitter.

7. Wait 3 seconds and turn OFF the aircraft.

CAUTION: Keep aircraft away from magnetic sources such as cameras, camera mounts, speakers etc. These may interfere with the GPS system and loss of control may result.

Compass Error (LED Flashing Red and Blue)

If at any time you experience no throttle response after power up and the ailerons are deﬂ ected full right and the LED is ﬂ ashing red and blue, the aircraft is indicating a compass error. This may be due to a lost GPS signal or from powering on the aircraft at a new ﬂ ying location. Disconnect the ﬂ ight battery and perform the compass calibration procedure.

3. Turn the airplane switch to ON. The elevator will move up and down slowly, indicating the the GPS is searching for satellites. When GPS is aquired, the elevator will move quickly and then center.

• If you wish to change the virtual fence mode, input the transmitter stick commands as described in the Virtual Fence Mode and GPS section of the manual. The fence can be changed at any time before the home point is set.

IMPORTANT: The throttle is active but only slowly pulses the motor, allowing you to taxi the aircraft. Either taxi to or place the aircraft in the desired home location, pointing the nose of the aircraft into the wind and the desired takeoff direction.

4. Once the aircraft is on the ground at the desired home location, and pointed into the wind. Press and hold the HP/AL (bind) button.

• If either of the circle Virtual Fence modes are active or if virtual fence is off, all control surfaces will wag and the throttle will now operate, indicating the aircraft is ready for ﬂ ight.

• If the Airﬁ eld Virtual Fence mode is active, only the ailerons will wag left and right. Release the HP/AL (bind) button. location you must then indicate where the ﬂ ying side of the airﬁ eld is in relation to the home location. The throttle will be inactive until the ﬂ ying side direction is set. Set the ﬂ ying side direction by moving the aileron stick either left or right in the direction of the ﬂ ying area:

-If the ﬂ ying side is off the right wing of the aircraft as it sits in the home location, push the aileron stick right to the stop and release (as shown in the example). The right aileron will move up and down indicating right direction has been set.

-If the ﬂ ying side is off the left wing as the aircraft sits in the home location, push the aileron stick left to the stop and release. The left aileron will move up and down indicating left direction has been set.

Once the home location and ﬂ ying location is set, all surfaces will wag, indicating the aircraft is ready for ﬂ ight.

CAUTION: If the aircraft is in Airﬁ eld mode, the line that deﬁ nes the no ﬂ y

zone will be aligned with the center line of the aircraft, and approximately 10 meters behind you to ensure the fence does not interfere with take-offs or landings. Make sure the aircraft is point directly down the runway in one direction or the other to correctly set the Airﬁ eld mode. If the aircraft is not aligned with the runway, the no ﬂ y zone will not be set in the correct location.

Flight Modes

Beginner, Intermediate and Experienced modes still operate the same with SAFE+ as they did with SAFE. With SAFE+, The Holding Pattern (HP) and AutoLand (AL) modes may be used as well.

Holding Pattern and AutoLand Trigger:

Holding Pattern: Press and release the HP/AL (Bind) button. Press and

release the HP/AL (Bind) button again to exit.

AutoLand: Press and hold the HP/AL (Bind) button for 3 seconds. Press and release the HP/AL (Bind) button again to abort AutoLand.

Changing the ﬂ ight mode will exit Holding Pattern or AutoLand and resume manual control in the selected ﬂ ight mode.

The “I” button is used for these features on BNF models when using the recommended transmitter setup.

IMPORTANT: LAS is functional for all SAFE ﬂ ight modes except for Expert Mode. When the ﬂ ight mode is switched to Expert mode the LAS is deactivated and the pilot will have zero assistance on landing, a traditional manual landing of the aircraft is nessesary.

Virtual Fence Mode and GPS

CAUTION: Keep aircraft away from magnetic sources such as

cameras, camera mounts, speakers etc. These may interfere with the GPS system and loss of control may result.

Your aircraft uses GPS to establish a home location and a virtual fence to keep the aircraft within a given distance from the home location. While ﬂ ying, the aircraft will automatically turn around and ﬂ y back towards the home location if it approaches the edge of the virtual fence. Once back inside the fence, the aircraft will “wag” its wings, indicating full control has been given back to the pilot.

The Virtual Fence feature is active in all SAFE ﬂ ight modes, provided the GPS function is active. There are 4 variations of Virtual Fence mode, which are selectable from the transmitter while the aircraft GPS system initializes.

Virtual Fence Off: turns off the Virtual Fence function. Circle Virtual Fence, Small (Default): sets the virtual fence in a circle with a

radius of approximately 175 meter from the home location. Circle Virtual Fence, Large: sets the virtual fence in a circle with a radius of

approximately 225 meters from the home location. Airﬁ eld Virtual Fence: sets the virtual fence in a rectangle of approximately

400m long x 200m wide and establishes a “no ﬂ y zone” approximately 10m (about 30 feet) inside of the center line.

LED Indication

Virtual Fence Off: Slow yellow ﬂ ash until home point is set. Once

home point and direction is set, a solid LED (without LAS installed). Circle Virtual Fence, Small (Default): 1 Red, 1 yellow ﬂ ash until home

point is set. Once home point and direction set, a solid LED (without LAS installed).

Circle Virtual Fence, Large: 2 Red, 1 yellow ﬂ ash until home point set. Once home point and direction is set, solid LED (without LAS installed).

Airﬁ eld Virtual Fence 3 Red, 1 yellow ﬂ ash Set home, slow yellow ﬂ ash. Set direction, right or left aileron depending on direction of ﬂ ying ﬁ eld. Home point and direction set, solid LED without LAS.

*A purple ﬂ ash will follow all mode indicators to indicate LAS is installed.

Once a Virtual Fence mode is chosen, the aircraft will remember that mode until another mode is chosen. It is not necessary to select the Virtual Fence mode every time the aircraft is powered on.

WARNING: Never attempt to ﬂ y under the no ﬂ y zone. The bottom of

the no ﬂ y zone is elevated to only allow for taxiing of the aircraft in the pit area of the airﬁ eld. Due to variances in the barometric sensor, attempting to ﬂ y in this area may cause the aircraft to suddenly ﬂ y back toward the home location, during which time the pilot will have no control over the aircraft until the aircraft reaches the home location. The pilot will have no way to avoid any obstacles between the no ﬂ y zone and the home location.

Holding Pattern (HP) Mode

If at anytime the aircraft seems too far away, press and release the HP/AL (bind) button on the transmitter.

The aircraft will maneuver to an altitude of approximately 120 feet (36m) and begin to ﬂ y a circular pattern over the home location.

If Airﬁ eld Virtual Fence mode is active, the aircraft will ﬂ y to approximately 120 ft (36m) altitude and ﬂ y a circular pattern about 100 ft (30m) in front of the home location.

The aircraft ﬂ ies fully autonomously when HP mode is active. The transmitter sticks have no control.

NOTICE: As a safety precaution, Holding Pattern mode will not function when your aircraft is below an altitude of approximately 20 ft (6m).

To deactivate HP mode and regain control, press and release the HP/AL button again or change ﬂ ight modes.

IMPORTANT: When the HP feature is activated, the aircraft should immediately respond to the command. If the aircraft does not respond immediately, GPS signal may have been lost. In this case, the aircraft will have to be ﬂ own back to the home location manually.

Failsafe (LED: RED SLOW FLASHING)

If at anytime the aircraft loses radio connection, the aircraft will activate Holding Pattern mode until it re-establishes radio connection. If radio connection is not regained, the aircraft will land near the takeoff location as in AutoLand mode.

Holding Pattern Mode

If radio connection is lost while the aircraft is already in Holding Pattern Mode, the aircraft will circle for approximately 35seconds and then set up to land as in AutoLand mode.

Deactivating GPS in Flight

If the GPS system malfunctions while in ﬂ ight, deactivate it to regain full manual control.

To deactivate the GPS in ﬂ ight:

1. Press and hold the HP/AL (bind) button down and fully cycle the ﬂ ight mode switch 3 times. The rudder will wag to indicate GPS is deactivated.

2. Set the ﬂ ight mode switch to beginner mode for full SAFE Plus function. The GPS system will remain off until the aircraft is landed and the ﬂ ight battery is unplugged and reconnected.

NOTICE: If GPS is deactivated, none of the Virtual Fence modes, Hold Position mode or Auto Land mode will function. The pilot will have to manually ﬂ y the aircraft back to a safe landing.

AutoLand Mode

When you are ready to land or your ﬂ ight timer has signaled, press and hold the HP/AL button on the transmitter for 3 seconds.

The aircraft will instantly respond and begin a landing approach in the direction set during initialization. The aircraft will land near your initialization point/location and come to a complete stop.

When AutoLand is activated, you can still control the aircraft to avoid obstacles like trees or poles. The aircraft will allow you to make corrections if you apply aileron or elevator commands, and will momentarily return throttle control to the throttle stick while the elevator or aileron commands are being used. Once clear of the obstacles just let go of the control sticks and the AutoLand feature will take over and resume the landing.

At any time you can abort a landing by pressing and releasing the HP/AL button or by changing the ﬂ ight mode.

If you want to takeoff again after landing pull the throttle to low position and then press the red HP/AL button again to deactivate AutoLand, or change ﬂ ight modes.

IMPORTANT: The AutoLand feature can not be initiated when your aircraft is below an altitude of approximately 20ft (6m).

NOTICE: The AutoLand feature does not possess the ability to avoid obstacles. Ensure that your ﬂ ying location is free of obstacles (trees, buildings, etc) before you start ﬂ ying.

Manually Assisting AutoLand Mode

No stick inputs are required when AutoLand is activated. However, stick inputs can be used at anytime during AutoLand to avoid an obstacle, lengthen the landing or smooth the ﬁ nal ﬂ are on landing.

Aileron stick:

Use the aileron stick to steer left or right to avoid an obstacle or make slight heading adjustments when on ﬁ nal approach. When aileron is given, the throttle will automatically advance slightly. Release the aileron stick and the system will take over full control.

Throttle stick:

Use the throttle stick to set a throttle max point. When elevator stick input is given, the throttle will go to the max point.

Elevator stick:

Up elevator: Allows the aircraft to stretch its approach by gaining altitude. When up elevator is applied the throttle increases to the throttle max point that you have established with the throttle stick. As the aircraft passes over the runway threshold, pull the throttle stick fully back and use up elevator to ﬂ are the aircraft to a soft touch down on the runway. This is the best practice for landings and will help prevent accidental propeller strikes. Down elevator : Allows the aircraft to stretch its approach without gaining or losing altitude. When down elevator is applied, the throttle increases to the throttle max point that you have established with the throttle stick without gaining or losing altitude. As soon as the right stick is centered, the system will take over full control again.

Example: When landing into a headwind, set the throttle stick to approximately 3/4 power. When the elevator stick is moved to extend the landing approach, the power will only progress to 3/4 power. Set to a higher throttle point in stronger wind or lower throttle point in low wind.
