FCC Statement
This equipment has been tested and found to comply with the limits for a Class A digital de-
vice, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference, in which case the user will be required to correct the
interference at his own expense.
Changes or modications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the device.
The antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 20 cm / 7.87 in from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter. End-users must be provided with transmitter operating
conditions for satisfying RF exposure compliance.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.

Safety Instructions
An R/C controlled helicopter is not a toy! While moving, the rotor blades
pose a serious danger to persons and things. You must obey all safety
instructions of the manufacturer for operation of your helicopter.
VBar is not an autopilot! VBar may be installed in model helicopters suitable
for ying without ybar. During installation and operation you must follow
all instructions given in the software of the radio and in manuals. VBar may
not be operated in wet conditions (high humidity or rain). If the helicopter
shows vibrations during ight, operation is to be stopped immediately. Do
not continue ying until the cause for vibration has been eliminated.
• Disconnect motor wires or remove the pinion gear to avoid acci-
dental spooling up of the helicopter while setting up the speed con-
troller (ESC), or when loading unknown setup, as they may contain
different speed controller settings as you have on your heli!
• Make sure you use a sufcient power supply.
• Fail safe will be set automatically by VBar/VBar Control (motor off,
servos on hold position).
VBar EVO and high servo frequencies
Your VBar NEO can—with update to Pro or Pro+Rescue—
drive suitable servos with higher frequencies than before.
Similar to overall gyro gain (too high = oscillation,
wobbles, shaking), a wrong setting can degrade the
ight performance, or even endanger/destroy the model.
Please make sure you read the following tutorial before
changing the default settings!

1. Itemsneededforrstinstallation
On rst installation, you will need:
• VBar EVO with built in VBar Control VLink
Receiver and a VBar Control radio
• Power supply (BEC or receiver battery).
• Helicopter with servos installed, but not yet
connected! Only digital servos allowed!
• Pitch Gauge (swash plate levelling tool)
• For updates and extensions of VBar EVO you
need the VBar Control Manager software which
you can download conveniently from www.vstabi.
info.

2. Update and Registration
Before beginning a setup, register and update your VBar Con-
trol and VBar EVO. Open the VBar Control Manager, connect to
your computer using the USB C wire, only then power up your
VBar. The LED will ash white. The update will be performed
automatically if necessary. During the update, the LED will
light up yellow briey, then start ashing green. Disconnect
the USB wire and power cycle your VBar, and it will start up
for normal operation, ashing blue during initialization, then
red-green. If you want to use the VBar Control Manager again
(e.g. to access the App Store), just power cycle your VBar. It
will start up in update mode again as long as it is connected
to your computer.
Click on Applications in the VBar Control Manager to access
the App Store, where you can register your new VBar to your
MikadoID with one click of your mouse.
Perform an update of your VBar Control, too.
3. Preparing the Helicopter
First you need to assemble the helicopter in accordance with
manufacturer’s instructions. Flybarred rotor systems are not
supported. It is very important that you assemble the helicopter
mechanically correct with exact symmetry and geometry. This
is to ensure that you do not run into problems resulting from
mechanical inconsistencies later.
4. Bind procedure, programming
VBar will go into bind mode after approx. 10 seconds. The LED
will ash green-red to indicate it‘s ready for binding.
Refer to your VBar Control Manual to bind your VBar to your
VBar Control Transmitter.
5. Wiring your VBar
Connectors
ESC Electronic Speed Controller
TAIL Tail servo
CH1-4 Swash plate servos according to diagram in the software
AUX1-3 Additional functions
RPM RPM sensor input
USB USB wire
TELE 1, TELE 2 Telemetry bus for VBar Control.
Power supply may be connected to any port. There is no voltage divider
needed for rpm sensors. Make sure all components support the input voltage
connected. For further applications (additional functions) see App in VBar
Control and online manual on www.vstabi.info.
6. Pre-ightcheck
Before each ight you must double-check the active
direction of the swash plate and the tail rotor. To do so, lift
the helicopter up and move it along the three axis.
7. Initialization (Pitch Twitch, V is lit)
During Initialization, VBar goes through a self-test. The LED
will ash blue, then. The helicopter must be at rest during this
test. When the test is nished, you will see a brief twitching
(jump) of the swash plate, VBar Control will show ‚Connect‘.
Also the V will light up solid green.
11. Operation
Upon successful initialization of the VBar and pre-ight check
you may proceed to the maiden ight with your VBar. At the
eld you may further adjust any setting using your VBar Control.
Trim ight:
During a trim ight, VBar performs all necessary trims of the
helicopter automatically (elevator, aileron, tail). A trim ight is
not necessary if the servo linkages are installed mechanically
correct, the swash plate is leveled, and the center of gravity
is set properly.
To perform a trim ight, turn on the helicopter while the stick
for collective is at full positive. The VBar conrms this with a
short double-twitch (jump) of the swash plate. With VBar
Control, enable trim ight in Flight Parameters. It is best to
perform the trim ight in very calm weather conditions. For
further information on how to perform a trim ight, click on
“Trimightinfo” in the ight menu, check out vstabi.info, or
consult online help (?) on VBar Control Touch.
