Lithium Polymer Battery Operating Instructions
• YOU MUST READ ALL OF THE SAFETY INSTRUCTIONS AND WARNINGS BEFORE USE.
• Lithium Polymer (LiPo) batteries are volatile. Failure to read and follow the proper use and charging instructions below may result in fire, personal injury and/or damage to property.
• Motion RC / Roban Model does not assume any liability for failures to comply with these warnings, instructions, and safety guidelines.
• By purchasing this battery, the buyer assumes all risks associated with LiPo batteries. If you do not agree with these conditions, return the battery immediately before use.
SAFETY
• Only use a charger which is specifically designed for Lithium Polymer batteries.
• Never charge batteries unattended. You should constantly observe the charging process and immediately react to any potential problems that may occur.
• Batteries should be placed on a heat-resistant, non-flammable surface during charging.
• If you see the battery balloon or swell, stop charging immediately. Disconnect the battery and observe it in a safe place away from flammable materials inside a fireproof container for approximately 60 minutes. Continuing
to charge a battery that has begun to swell will result in fire and/or explosion. Never use or attempt to charge a battery that is swollen or ballooned.
• Certain Li-Po chargers may not work properly and may cause them to charge Li-Po batteries incorrectly or at an improper rate. It is your responsibility solely to assure the charger you purchased works properly. Always
monitor the charging process to assure batteries are being charged properly. Failure to do so may result in fire and/or explosion.
• Never open the battery covering, modify the battery connector, or short the wire leads of a battery. These actions can result in fire and/or explosion.
• Never puncture a battery or store it near sharp or pointed objects or surfaces. A punctured battery can result in fire
• If the battery is involved in a crash, put the battery in a safe fireproof area and observe for 60 minutes. It is highly recommended that batteries involved in a crash are removed from service. Internal damage not obvious
to the naked eye can result in fire.
BEFORE CHARGING
• Please read the charger instruction manual completely before charging your battery.
• Always check the voltage of batteries before charging to ensure they are at or above the minimum safe starting voltage. Never charge a battery pack which is below 3.7V per cell. For example, a 3 cell (3S) pack should not
be charged if it is below 11.1V. If the starting voltage is below recommended levels, then the batteries have been over discharged or have experienced a failure and should NOT be charged.
• Ensure each cell's voltage is within 0.1V of the others. Do not attempt to charge a battery with imbalanced cells.
• Always inspect the battery for any type of damage before charging. Look for any damaged leads, connectors, broken shrink wrap, swelling of cells, or other irregularities. Do not use the battery if you find any of the above
issues with your pack.
• Ensure you are using battery charge leads which are compatible with the connector on your battery.
• Check the polarity of the battery cable and charger lead carefully before the connection to avoid any short circuit.
• Always verify the charger is in good condition before use. A poor-quality charger can be dangerous. It is solely your responsibility to assure that the charger you use works properly. Failure to do so may result in a fire
and/or explosion.
• If your battery develops a distinct smell, often sweet or acrid, this can be a sign of internal damage. Discontinue use immediately and do not charge.
CHARGING
• Always charge batteries in an isolated area on a heat-resistant, non-flammable surface (such as concrete) outside of buildings and away from flammable materials, liquids and surfaces.
• Never charge batteries that are hot to the touch. The battery temperature should be the same as the ambient temperature before charging.
• Always select LiPo balance charging. This requires the use of the white JST/XH balance connector for all charging.
• Make sure to set the charger to the correct number of cells and voltage shown on the battery label.
• The charger should never be set to charge batteries at a rate greater than 1C (One (1) times the capacity of batteries in amp hours).
• Never charge LiPo batteries over 4.2V per cell. Charging a LiPo battery for an extended period will result in fire and/or explosion.
• Never charge multiple battery packs together in series. Charge each pack individually.
• Use suitable and good quality chargers with proper certification marks (UL Listed, etc.). Never use inexpensive and low quality chargers.
• Always disconnect the battery connector from the charger’s charging cable first. Do not remove the charger’s charging cable from the charger first because its exposed leads could contact each other, causing a potentially
dangerous short in the battery attached to it.
STORAGE
• Store at room temperature between 40 and 80 °F (4 to 27 °C). Storage at higher temperatures may result in failure and fire.
• Always store batteries between 3.75V and 3.9V per cell. Storage at higher or lower voltages may result in damage.
• Never store loose batteries together, the terminals may contact one another causing a short circuit.
• Always store LiPo batteries in a safe fireproof container away from flammable materials.
• Never store batteries in extreme temperatures or direct sunlight.
DISCHARGING
• Never discharge LiPo batteries at rates higher than specified C rating on the label.
• Never allow the temperature of batteries to exceed 140 °F (60 °C) during discharge. Adequate cooling for batteries is required, especially when discharging at or near maximum rates.
• Never discharge battery to a level below 3V per cell under load or 3.7V per cell resting.
• Do not run the battery down to the ESC cutoff voltage. Operating an RC product to the point that its motor stops working will result in irreparable damage to the battery. The ESC cutoff voltage is for the safety of the
aircraft and bystanders. When the battery is discharged this far, it should be removed from service.
• Never leave battery unattended during the discharging process.

Preparation
Removing the items from the packaging
To unpack the product safely:
• Remove all packaging tape that ties down the fuselage inside the transport carton.
• Remove the fuselage from the carton. With the landing gear not extended, it is easy to scratch the painted underside. Place
on a clean, soft cloth.
• Begin unpacking the mechanics, rotor blades and the accessories. Check if all parts are included.
Storing the product
The paint used on the fuselage is made from an environmentally friendly polyurethane resin but is not UV-resistant. It is important to
store the product in a location that protects it from prolonged exposure to sunlight, as the colors may fade and the clearcoat may
yellow.
The epoxy resins and PVC windows have a low glass transition temperature and can become soft and permanently deform at
temperatures as low as 50°C/120°F. Avoid storing the product in a car on hot days or in garages or sheds where temperatures may
exceed this level.
The batteries used in the RC product must not exceed temperatures of 60°C/140°F to prevent damage. Like all electronic products
that bring different metals into contact, exposure to humidity can cause the surfaces to oxidize and potentially harm the product.
To store the product safely:
• Don’t store above 50°C/120°F
• Don’t store lithium batteries above 60°C/140°F or below 0°C/32°F
• Charge lithium batteries only with appropriate chargers
• Use a BAT-SAFE for additional safety on batteries
• Don’t store with exposure to sunlight.
• Don’t store under humid conditions of 60%RH or above over prolonged periods.

Installation of rotor blades
Properly install the rotor blades using the preinstalled screws and lock nuts, following the illustration for the correct rotational
direction. Remove the screws, insert the blades and install the blades. Avoid overtightening the screws, as the blades should not be
too loose in the grips, but also be easily movable by hand inside the grips.
If the blades are overtightened in the grips, this can cause vibrations when the helicopter spools up.
Page 17
Installation of the battery
To begin the installation process, start by removing the nose cover to gain access to the product's interior. Install the battery on its
mount plate as shown and secure with the Velcro by tying it down with a bit of tension. The surface of the tray is rough, providing
enough grip to prevent it from moving if tied down properly.

Page 18
Center of gravity
Install the battery in the center of gravity as shown. Loosen the Velcro strap and move the battery forward of aft until, with the canopy
on, the helicopter is balanced, e.g. the main blades are perpendicular to the horizon. Lift the helicopter on the rotor cap and let it hang
freely and adjust until the main blades are level!
Mark the position with a sharpie for your convenience when you exchange batteries on the battery tray. Always secure the battery
with the Velcro firmly. It mustn’t come loose and move while in flight.
Page 19
Operation/Use
Charging the batteries
Before charging, ensure that you follow the battery operating instructions outlined in Section 3.3 of this manual to prevent damage
to the battery or charger. Proper handling and care during the charging process are crucial for maintaining the longevity and safety of
the battery. Follow the steps below carefully when using the lithium balance charger.
• Connect the charger to a power outlet (100-240VAC). Check the charger’s display for ‘000.’ This indicates the charger is
functioning correctly.
• Choose the correct charging port for your battery. For a 4S 14.8V battery, use the right-hand side port.
• The charger display will show the total voltage once connected.
• When charging is complete, disconnect the battery.
Once the display shows "FUL" and the fully charged voltage alternates on the display “168”, the battery is fully charged. Disconnect
the battery from the charger and unplug the charger from the power outlet.
Charger information
This charger operates with a low charge current. The battery supports charging at a 1C rate (full charge within 1 hour), which translates
to a 5A charge current or approximately 80W of real charging power. However, this charger has a rating of 1A, respectively 15W, so a
full charge may take up to 5 hours, depending on the battery's charge level. Please only use chargers specifically designed for RC
batteries with balance port (white plug) connectors under any circumstance. For safe charging, it is recommended to use a BAT-SAFE
charging enclosure.

Switching the equipment on and off
Turn on the Transmitter
To power on the transmitter, insert 4 AA batteries (not included) into the battery compartment at the back. Next, press and hold both
power buttons simultaneously for two seconds to switch it on, and then release the buttons. In case you receive a warning message
regarding the switches, make sure to flip all four switches on the radio into the top position before switching on the transmitter to
avoid any startup issues.
Page 21
Turn on Helicopter
Install the battery at the appropriate center of gravity location and secure it using velcro straps, ensuring a tight fit. Position the
helicopter on a flat, level surface for takeoff, free of dust and debris. Connect the power plug as shown, ensuring a fully inserted
connection to prevent power loss during flight. Install the canopy.
Wait for the Controller initialization
The controller goes through a boot sequence. It will start flashing green/red, then red and finally flash green. With the mode switch
in the down (3D) position, you can actually start flying the machine, if you are a seasoned pilot. But let’s get started in the GPS mode.
So please make sure the mode switch is in the up (GPS) position. If indoors, you won’t be able to take off in GPS mode.
© 2024 Roban All Rights Reserved. 21
Page 22
Getting ready to fly in GPS mode
Turn on the radio control with all levers in the up position. Dial the motor switch A in the down (STOP) position and leave the mode
switch in the up (GPS mode) position.
With the controller/helicopter being powered up already from the prior step, and the helicopter being indoors without a GPS signal,
the LED will double flash green or blue. This signals the absence of a sufficiently good GPS signal. Once you are outdoors and the GPS
signal is acquired, it will keep on flashing green in GPS mode, in the same way it flashes in the 3D or STABI mode switch positions with
a single flash.
Once the GPS position is locked, you will get a green single flash instead of a double blue flash in GPS mode. It may take up to 2
minutes to acquire a GPS signal. Leave the canopy off and observe, once you are used tho this startup procedure you basically just
wait for a moment until the GPS signal is acquired.
If the sky is blocked by clouds, use droneweather to check conditions. Without a good, high quality GPS signal the machine won’t let
you take off in GPS mode, but in both other flight modes.
Page 23
Arm the helicopter
The controller has a double arming feature to prevent accidental operation for your safety. Before you can start the motors, you must
arm the control unit. It’s done by a simple stick motion on your radio (left stick down and to the middle) and hold it there for 3 seconds.
The controller light will go from green single flash to permanent green. It is now armed. If there is no GPS signal and you have a double
flash, it won’t arm itself!
Start the motors
When you now flip the motor switch A UP, both the main and tail rotor (tail might not until the yaw stick or helicopter is moved) will
start to spool up. Otherwise the helicopter will disarm itself after 15 seconds and start to flash green again if the motors aren’t turned
on, so make sure that not too much time passes between arming from the prior step and switching on the motors. Do not switch off
the motors during flight, unless in emergency situations, as the helicopter will fall to the ground.

Fly the Helicopter
Once the main rotor is idling at constant speed (the rotor sound pitch doesn’t rise anymore), gently lift the helicopter by pushing the
lever upwards as shown, making sure to lift it to a height of at least 3 feet (1 meter) of clearance for safe hovering and maintaining
position. Its now up to you to fly and land the helicopter.

B-206 Water Tank Operation
The B-206 is equipped with fully working water tank that includes a water pump. Before powering on the helicopter, fill the water tank
with tap water until full. Do not seal the filling nozzle, air needs to enter freely when the pump is active, or the tank will get deformed.
Once airborne, you can activate the pump by flipping Switch B to the down (PUMP) position. Once the water has been emptied, turn
the pump off by switching the flip Switch B back into the upper (OFF) position.
The pumps parts are fully insolated from the water, there is not need for you to dry the tank before storage to prevent
rusting/oxidation.

GPS near Ground Interference
We advise against hovering within 3 feet (1 meter) of the ground in GPS mode for extended periods. GPS relies on signals from
multiple satellites, calculating position based on the time it takes for these signals to reach the receiver. However, when flying close
to the ground, these signals can reflect off surfaces—such as moist gravel or concrete—and bounce back to the receiver, causing
inaccurate readings.
This phenomenon, known as multipath error in GNSS systems, becomes more pronounced as the antenna gets closer to reflective
surfaces. In the case of small radio-controlled aircraft, the risk of interference increases, potentially leading to erratic aircraft
movements. For optimal performance and safety, maintain a higher altitude when hovering in GPS mode.
For this reason, we strongly advise against operating in GPS mode near the ground, except during takeoff and landing.
Keep Track of Flight Time
With a fully charged battery, you can fly for up to 15 minutes before needing to land and recharge or replace the battery. Since the
controller maintains altitude using GPS, it may be difficult to notice when the battery is running low based on the helicopter’s flight
behavior alone.
We recommend timing your flight from the moment you turn the motors on. After about 12 minutes, start heading back to your
landing spot and prepare to land. The radio control has an integrated timer function that can be activated to display the flight time.
Instructions for using this timer are provided in the radio control section of this manual.
It is important to monitor the flight time to avoid activating the automatic landing feature triggered by low battery voltage.

Landing the Helicopter
When you are ready to land, guide the helicopter to a suitable flat area, such as your original take-off spot, using the flight controls.
Gradually lower the helicopter until the landing gear touches the ground. Once the helicopter has landed, immediately shut off the
motors by flipping Switch A to the "Motor Off" position. Avoid leaving the helicopter with the blades spinning on the ground, except
during take-off or landing.
Flight Modes

GPS MODE
ANGLE MODE
MANUAL MODE
Controller Flight Mode Description
The helicopter offers a variety of control modes, each of which produces a different flight performance of the aircraft. The flight mode
is controlled by Switch C, which offers three modes that can be switched between:
Additionally, from GPS mode you can enter the RTH MODE. The exact functionality is explained below.
Use cases for each mode
GPS Mode: Stable position and altitude, best for beginners.
ANGLE Mode: Self-leveling but requires manual control of height and position.
MANUAL Mode: Full manual control, no automatic stabilization or leveling.
RETURN TO HOME (RTH) Mode: Full automatic control, return to take off location, auto landing.
GPS Mode
In GPS mode, the helicopter uses the GPS sensor to stay in one place and keep the altitude as long as the control stick is not moving.
By moving the control sticks, you move the point and heading the 3D space, and the helicopter will automatically move to this new
location. All directions are fully controlled by the controller. This mode does not require constant control, you can leave your hands
off the control sticks, and it will stay steady in place, and even resist wind and keep the position. The GPS mode is dependent on the
GPS position signal, so a 3 x 3 x 3 ft tolerance window over time is within the actual specifications of accuracy.
Only if you take of in GPS mode the RTH Mode is accessible.

Page 30
ANGLE Mode
In angle mode, the helicopter does not use GPS to stay in one place, but stabilizes the helicopter by returning to a level attitude on
the roll and pitch axis if you let go of the control sticks. But it doesn’t control the position or height like in GPS mode. In Angle Mode,
the helicopter may drif in position and change its altitude, and you will need to control its movement manually. This mode requires
constant manual control.
We advise that you familiarize yourself with these control modes and use them appropriately to suit your flight needs.
If you switch from GPS to Manual or Angle mode while hovering, the helicopter may drop in altitude. Be prepared to compensate
by manually adjusting the throttle.
Note: If you take off in Angle mode, the Return to Home function will not work. You must take off in GPS mode for this feature to
be available.
Manual Mode
In this mode, you have full control. The helicopter does not use GPS to stay in one place, nor self-stabilization via accelerometers. As
a result, you will need to control everything, including altitude and direction as any regular 3D helicopter. The model will keep the
angle on each rotational axis stable as long as the stick of the according axis is in the center postion, as any typical 3D helicopter gyro
for 3 axis offers. If you took off in this mode, the return to home function cannot be activated. This mode also allows for the highest
overall flight speeds in any direction but requires constant manual input.
When you switch from GPS mode to 3D mode during flight, the helicopter will drop in altitude because it loses the automatic height
adjustment. Be ready to control it manually to prevent a crash. Compensate for this by making an upward pitch stick movement if you
see the machine dropping, and a downward movement if the machine climbs. Keep in mind that this maneuver can be dangerous if
you're a novice, especially if you're close to the ground. Only experienced pilots will be able to quickly adjust for the loss of auto
altitude hold function.
In 3D mode, the helicopter does not automatically maintain its position, so it may drift in any direction. You'll need to compensate for
this movement manually. We strongly advise that you have ample flight experience and skills before attempting to use 3D mode.
If you switch from GPS to Manual or Angle mode while hovering, the helicopter may drop in altitude. Be prepared to compensate
by manually adjusting the throttle.
Note: If you take off in Manual mode, the Return to Home function will not work. You must take off in GPS mode for this feature
to be available.
Return to Home (RTH) Mode
This functionality is only available if the machine was armed and taken off in GPS mode only. It is not accessible if you armed the
machine in Manual or Angle mode.
It is an automated flight control that will return the aircraft to the take off point, land it and shut off the motors. There are several
ways to enter this mode, either manually or by a safe-guard automation. Once engaged, the aircraft will rise to 15m above the starting
point flying height, then turn into the home point heading and then fly towards the home point. Once the home point is reached, it
will turn the tail back into the take-off heading, then lower the altitude at a constant sink rate until it has landed and then switch off
the motors.
Page 31
OFF
RETURN TO HOME
While the machine is in its decent phase after reaching the home point, its possible to adjust the position via the pitch and roll control
sticks to get the exact position right.
The RTH mode can be interruped manually. The radio control mode switch has to be in the GPS position and the RTH switch has to
be flipped into the RTH position and then back into the OFF position. This will interrupt the RTH mode.
Please note that while in return to home mode, the helicopter cannot detect or avoid obstacles, so it is necessary to ensure that there
are no obstacles between you and the starting point.
The controller offers three different ways to engage the RTH function:
Loss of Signal:
If the machine was unlocked and taken off in GPS mode, and the transmitter signal is interrupted for more than 3 seconds, the flight
control system will enter the RTH mode. It will take control of the helicopter via the RTH mode and automatically land and shutoff
unless interrupted by the user. This only will be possible if the radio signal returns to normal during the return flight, and the user can
turn on (while being in GPS mode) the RTH mode and off again during the return flight.
Low Voltage Return:
If the machine was unlocked and taken off in GPS mode, and the flight control detects that the flight battery has a too low voltage,
the controller will engage the RTH mode. In low voltage situations, the motor may not be able to output enough power to maintain
altitude and eventually lead to the helicopter falling, crashing, or getting damaged. To prevent this danger caused by insufficient
battery voltage, the flight control system will judge whether the current voltage is sufficient. If the actual voltage falls below the
programmed threshold, the helicopter will automatically enter the RTH. The user can turn on (while being in GPS mode) the RTH mode
and off again during the return flight.
On Command Return:
In the flip is switched into RTH postion (down), the model will also execute the return to home maneuver.

Controller Port Wiring and Specifications
The controller can be powered either through the Batt.In connector or the USB connector.
An internal step-down converter provides 5V DC from the Batt.In connector to power the RC.In receiver port, which is isolated from
the other channels.
The servo and ESC channels share a common power and ground connection, but do not have their own internal power supply. Instead,
the ESC supplies power to the servos through a 7.4V DC BEC in a high-voltage configuration.
Note that the power connector is not polarity-protected.
Channels 1 through 10 are bridged for power and ground and must be supplied with power from an external source, such as the ESC.
Channel 13 (the receiver port) is powered internally by a 5V DC supply.

LED Light system
The helicopter comes equipped with a preinstalled LED light system, which has its own dedicated controller. The system is powered
by the 7.4V BEC supply through the bridged rail on the main controller, and is connected to servo port 6.
The LED controller can be controlled by the radio control. The right-hand side switch on the back side of the radio can be used to cycle
through 8 different patterns. The position light pattern always starts on the same pattern mode on power up. The controller is separate
from the main controller and can be controlled immediately.

Troubleshooting, Support and Warranty
Adjusting the controller
The controller is based on the ArduCopter Heli open-source software. To modify the parameters, you can use the APM Mission Planner,
which is available for iOS, Windows, and Linux. It connects via USB (or optionally through a wireless WiFi connection).
We provide a separate manual and video tutorials covering the usage of the software and the setup process in detail. The ArduCopter
platform offers a wide range of features, and many parameters are accessible for adjustment. However, we recommend making
changes only when necessary, such as after replacing servos that require setpoint adjustments.
For further guidance, please visit our website at www.robanmodel.com . On the product page, you will find links to the control
software manuals and support videos.
Helicopter blade tracking and maintenance
The helicopter comes fully adjusted, so no blade tracking is necessary. If you use our original rotor blades, even replacing a set will not
require blade retracking.
Blade tracking refers to the process of ensuring that both rotor blades follow the same path during rotation. Misaligned blades can
cause vibrations and reduced flight stability. Typically, blade tracking involves adjusting the pitch of one or both blades to make sure
they rotate in the same plane.
However, if a mishap damages the blades, or bends the rotor grips or grip link connectors, it can misalign the control system. In such
cases, we recommend replacing the grips and pitch levers as well.
For this specific helicopter, there is no need to adjust blade tracking as the control system is non-adjustable. After a crash, the only
thing you may need to verify with a pitch gauge is that the swashplate is still level. Adjust any necessary center points through the
controller software interface, rather than making mechanical adjustments to the helicopter itself.
