1. SAFETY
R/C models such as helicopters are not toys! It is necessary to check all the
manufacturer instructions of the model, comply with local laws, carry out
preventive checking of the model and repair all mechanical and electrical
concerns and failures immediately.
Rotor blades and propellers rotate at high speed and can lead to serious injury
to persons or damage to the model if not respected.
If you encounter any problems, contact your model shop or experienced
modelers.
Especially pay attention to your own safety and the safety of others. Never fly
amongst or over people, animals, or on private property without prior
authorisation from the land owner.
Fly only in safe places where no additional damage is possible to other objects,
because the model can become unmanageable for various reasons, such as
failure of electronics, mechanical failure, pilot error or radio interference.
Do not try to control crashed models nor repair damaged parts, always
replace them with new ones.
Never fly the model with excess vibrations, it may cause unwanted flight
characteristics or become uncontrollable. Find the source of the vibrations and
fix the problem.
Spirit is not an autopilot, it is necessary to have knowledge of flying R/C models.
The system is only designed to improve flight performance.
We recommend using R/C simulators designed for training before the first flight.
The user takes full responsibility for any damage or injury caused whilst flying
an R/C model equipped with one of our devices. The manufacturer is not able
to guarantee the conditions in which the unit is being used.

2. INTRODUCTION
Spirit is a device for stabilising R/C models such as flybarless helicopters,
features include electronic paddle simulation, vibration logging, support for
various Tx/Rx types and a rudder gyro for those who want to continue using a
mechanical flybar.
Thanks to flybarless mechanics, the system improves the efficiency and
maneuverability of the helicopter and it's stability whilst also extending flight
times.
Flight characteristics are easily customisable according to your preferences,
from stable flight for beginners to demanding acrobatics with maximum agility
for experts.
Because the Spirit uses the most advanced technology, the model can be
controlled very precisely even under harsh conditions such as strong winds
whilst maintaining a constant pirouette.
This user guide will help you to properly mount the unit on a model and carry
out the configuration step by step to prepare it for the first flight. It is very
important to carefully adjust everything to make your first flight as pleasant and
trouble free as possible.

software updates.

3. INSTALLATION
The mounting of Spirit plays an important role for the correct operation of your
model.
Find a suitable location where vibrations are as low as possible - that location is
usually given by the manufacturer for mounting the gyro.
A very significant factor is that the unit should be positioned exactly
perpendicular to each rotational axes.
The unit can be mounted in two different positions. Depending on your
preference and available space it can be:
Horizontally
The unit can be mounted horizontally so the connectors face upwards. It can
be rotated by 180°on the yaw axis so that the connectors can be situated to
either the front or the rear of the model.
5
Vertically
The unit is located on the side so the connectors are also at one of the sides.
It can be rotated by 180°in yaw axis so that the connectors can be situated to
either the front or the rear of the model.
The unit must always be positioned parallel to the longitudinal axes of the
model.
In order to better insulate against any vibrations from the model, it is necessary
to choose the right double-sided tape. It should limit any transmission of
vibrations from the model to the Spirit which may produce undesirable flight
characteristics.
Vibrations may be caused not only from incorrectly balanced blades or
propellers, but also from damaged bearings, bent shafts and other
mechanical issues.

4. WIRING
Wiring to the unit depends on the type of receiver used.
Spirit can be set up as a standalone tail gyro or as a flybarless system.
NOTE
Spirit is pre-programmed to 1520µs servo neutral impulse and 50Hz frequency –
please ensure you have the correct servo parameters specified by your servo
manufacturer.
If the neutral impulse of your servo/s is different to the above, such as 760µs, do
not connect this servo yet as it could be damaged.
Some connectors have non-standard dimensions that could interfere with
neighboring connectors after plugging in the unit. As a solution, we
recommend replacing these connectors with JR or Futaba connectors.
Never plug a connector for powering the unit into the SYS or ELE/PIT/AIL
positions or you may risk damaging the unit.
4.1. STANDALONE GYRO AND FLYBAR
Owners of flybarred helicopters can take advantage of the heading hold gyro,
which keeps the tail in the direction given by the transmitter irrespective of
effects from wind or any outside forces.
It is required that you connect the rudder servo to the CH4 port of the Spirit
unit.
If you also use a standard receiver, you will need to connect GEAR (or AUX)
from your receiver to the AUX port on the Spirit unit.
Also, you will need to connect your receiver RUD port to the RUD port on the
Spirit unit.
If you do have a flybarred model, you can also connect the unit in the same
way as a you would a flybarless one. In this instance, you can use the full
potential of the unit including Stabilisation and Rescue mode. In order for this
to work correctly, it is necessary to tick the “Flybar mechanic” parameter in the
Stabi tab. All other parameters can be configured as with a flybarless head.

4.2. FLYBARLESS
Owners of flybarless helicopters can take advantage of the full capabilities of
the Spirit unit. The Spirit will stabilise the model on all axes and also make it less
prone to wind, extend flight times and increase the agility of the model.
Flight characteristics should be more stable which will allow the pilot to carry
out even the most challenging maneuvers.
Unlike flybarred helicopters, the cyclic servos on an FBL helicopter are more
directly connected to the rotor head and blades, so demands on the servos
are significantly higher. They should be stronger to cope with this and also
faster to respond as quickly as possible to any commands the Spirit unit sends
them.
Flybarless rotor blades are also different from blades designed for flybarred
models. For optimum flight characteristics it is recommended to use them.
When using the Spirit unit as a flybarless system, all servos should be connected
in the corresponding positions:
CH1 - aileron
CH2 - elevator
CH3 - aileron / pitch
CH4 - rudder

4.3. CONNECTION OF STANDARD RECEIVER (PWM)
For standard receivers it is necessary to use two normal and one special cable.
Three connectors should be plugged into the receiver and the end of this
cable to the unit.
The unit is powered by two cables from the receiver connected to AUX and
RUD positions. Throttle cable should be connected to the receiver as well.
The easiest way you can start is, connect RUD with Rudder output in the
receiver. Then continue with AUX which should receive Gyro Gain channel
output. At the end, connect Aileron, Elevator and Pitch channels.
You can do so gradually with mid-tests to check, whether connection is
correct. The diagnostics tab should be helpful too.
Never plug a connector for powering the unit to SYS or ELE/PIT/AIL ports.

4.4. CONNECTION OF SPEKTRUM DSM2/X SATELLITE
Connection to a BEC is optional. If the model is powered by an external BEC,
this must be connected to the AUX port. In the case of using an external BEC,
the power lead from the ESCs internal BEC must be disconnected.
A second satellite can also be connected, but this can only be achieved via a
special adapter connected to the RUD port. This adapter can be purchased
separately.
Before satellites can be used they must be bound to your transmitter, taking
into account any failsafes that need to be set.
This can be achieved by inserting a bind plug in the SYS port for DSM2 satellites
or the ELE/PIT/AIL port for DSMX satellites and then power cycling the Spirit unit
to start the bind process. Once successfully bound, the STATUS LED will go out
and the satellite LED will come on.
If the second satellite fails to bind, swap the satellites and repeat the bind
process. Be sure Receiver type in the software is configured to Spektrum
DSM2/X else binding process will not work.
Never plug a connector for powering the unit to SYS or ELE/PIT/AIL positions.
