Introduction
TRudder pedals let the virtual pilot to control the rudder just like a real pilot. This
device has not onboard controller and must be connected to the one of the following
devices:
▼CobraZ joystick,
▼Tiny Box external controller,
▼ThrottleBox external controller.
Standard UTP cable with two 8 position connectors 8P8C (often called as RJ45) at
each end is used for pedals connecting.
This manual contains recomendations how to assembly and set up pedals.
Pedals installation
1. General info
TRudder pedals are delivered partially dizassembled. Delivery set is shown on
fig. 1.1.
1.1.
The same cables are used for connections between many kinds of devises, such as
routers. ADSL modems etc. Do not even try to connect pedals to any device with
8P8C socket! If you connect pedals to any device except above mentioned it will be
damaged.

The back leg is attached to the case by two screws. Three adjustment holes make
possible to set the angle between the case and the leg thus providing pedal setup
for pilot foot size. The screw, drived into the fourth hole, is using as an axis. Before
the leg is fixed in a chosen position you can rotate it around this screw.
4.2. Choose an appropriate adjustment hole and insert the screw with washers into
it (fig. 2.6).

6.3. Choose one of the notches on the side edge of the foot bearing in a
correspondense of your foot size and thus the distance between fot bearing and
the support shaft (fig. 2.16).
2.16.
6.4. Fix the foot bearing using М4 screw with the shaped nut.
7. Install support shafts.
7.1. Put spring washer on the shaft screw body.
7.2. Drive suppport shaft screw into the force lever hole and tighten it using hex tool
(fig. 2.17) or screwdriver.

Support shaft height setup
1. General info
Usability of pedals is provided by support shaft height. You must rotate sincronizers
to set up this height. The height of both shafts in neutral rudder position must be the
same.
2. Order of setup
To set up support shaft height, execute the following operations.
1. Unclench syncronizer springs, turning off compressing nuts by included wrench
(fig. 2.1).
2.1. маю
2. Rotate ribbed tube of the syncronizer to set appropriate support shaft height.
3. Ensure that the height is in acceptance limits.
3.1. Pull down support shaft till it touches the foreleg damper.
3.2. Look at the frame in the case (fig. 2.2). The gap between the body of the spring
loaded screw and frame edge must be at least some millimeters.
2.2.
Fig. 2.1.
Do not install support shaft too high! In this case the parts of pedals construction
will be loaded too much and can be destroyed. Rotating ribbed tube do not unscrew
threaded rod end of the bearings from it!

4. Tighten the nuts, thus сompressing the springs to solid state.
5. Set up the height of the next support shaft by the same manner.
Pedals connection
Use included patch cord to connect the pedals to any controller. Plug one end of the
cable into
RDR Link socket on the fore side of the case of the pedals. The other end
plug into
RDR Link socket of Tiny Box controller or if you use ThrottleBox controller
to
Pedals socket. These conntrollers connect to USB port.
Pedals axis setup
1. General info
MARS sensor of the pedals is a Rx axis for Tiny Box controller. You must set up the
parameters of this axis using сonfiguration program. Use this link http://ftp.vkb
sim.pro/Programms/ to download this program.
This manual describes only few opportunities of this program. Detailed description
you can find in VKB NJoy32 controller configurator User manual. Use link http://
ftp.vkbsim.pro/Documentations/ to download file controller.pdf (Only Russian
language now).

2. Axis type
MARS sensor is a digital device. You must properly set its type. Activate Physical
Axes
tab (fig. 2.1).
2.1.
Choose D_MaRS value from Input combobox. This choise corresponds to digital
MARS sensor. Check
AC (Autocalibration) option. It allows automatic calibration of
the pedals with every connection.
3. Axis calibration
Checked AC option generally provides automatic calibration of the axis. For properly
autocalibration pedals must be in neutral position. If it is needed you can calibrate
pedals manually.
h
To calibrate pedals execute the following operations.
1. Activate
Physical Axis tab and check Cl option for calibrated axis.
2. Activate
Tools tab.
3. Push
Start Calibr button.
4. Move pedals between extreme positions for some times.
5. Push
End Calibr button.
You may push
Cancel Calibr button to reject calibration and do not save its results.
When you complete calibration check its results using, for example, DXTweak
program.
Fig. 2.1.
It is not recommended to calibrate pedals by Windows tools. If you have calibrated
the pedals in such manner, you must run DXTweak program to return them to initial
state. Push
Device Defaults button and then Apply button.
If any joystick with more than six axes is connected to a computer, DXTweak will not
work properly. In this case disconnect such joysticks.

If when the pedal is in extreme position but marker is not on range limit, it is
recommended to increase the support shaft height (see“Support shaft height setup”
on page 11). If it is impossible, set
Mpl value equal to 10.
4. Axis parameters setup
Set deadzones of the pedal axis using DzLo field (deadzone in the center) and DzHi
field (deadzones on range limits).
Use
Df option in the Common group to control the dynamic filtering of axis
response. Set degree of filtration in
Filter field and its treshold in Trh field.
Set number of digits for the axis in the
Precis field on the Logical Axes tab
(fig. 4.2). Recommended value for digital sensor MARS is 10.
You can choose name of the axis from
HID Usage combobox. It is needed, for
example, If some connected devises have axis with the same names. Be carefully
changing this parameters! In some cases the renamed axis will not work. If it
happens restore initial axis name.
4.2.
5. Response curves
Use the controls on the Response curve tab to set up response curve of the axis.
Execute the following operations.
1. Select the string with number, corresponding to the calibtrated axis. For TRudder
pedals it is the first axis.
2. Move sliders to shape response curve. The values in the fields will correspond to
sliders positions.
Linked option enables to link sliders positions. If the option is checked, when you
move one slider, the adjasent ones will move too. Set the degree of dependence
between sliders using
QFactor slider.
3. If you want to apply custom shaped response curve to the axis, check
Eq option on
Physical Axis tab for it.
Fig. 4.2.

Variants of pedals steadiness support
Rubber end caps of the legs provide pedals steadiness on most kinds of surfaces.
If you want to have aditional steadiness on firm and smooth surfaces, such as
parquet, laminated flooring board, marble etc., you can use included selfadhesive
silicon legs. Fasten two silicon legs onto the foreleg, one onto every back legs and
shortcross support.
To fix the pedals on the pile surfaces you can use included velcro strip. Extract
rubber end caps from the foreleg and stick this strip on it.
