Plus the 3SX features an additional mixer type for the control of tandem helicopters. For more info please see “Specifi c features of the 3SX”. The 3X expressly incorporates no horizontal or position stabilisation and is thus fully suitable for competition! Besides this, there is no difference in performance compared to the 3SX, plus it can be upgraded at any time to the full functionality of the 3SX.
Q U I C K I NT R ODU CT ION INSTALLATION MOUNTING POSITION Important is an orientation exactly aligned to the level of the main rotor or rotor shaft in all 3 axis, i.e. the assembly surface must be orthogonal or parallel to these. Contrary to normal tail gyros, this is particularly important to ensure that the head stabilisation maintains constant attitude even during pirouettes.
CONNECTION VIA SERVO OUTPUTS (STANDARD RECEIVER) VIA FUTABA S.BUS OR SUM SIGNAL (ROBBE, JETI, GRAUPNER, HITEC, ETC.) If the receiver features a sum signal (PPM pulse or ‚serial PWM‘) output, it can be connected via this output, so only one patch cable is needed. Activating this feature is done via PC software.
Do not move the heli/system for the fi rst fi ve seconds after switching on (LED fl ashes red). The system runs a self-test and needs standstill to perform this, as otherwise it does not activate the servos and starts to fl ash 3x red.
SETUP / ADJUSTMENT After installation, the system must be tuned to heli and transmitter, which fi rst includes adaptation of the transmitter to the system, followed by setting up the system to the model. The PC software includes a setup wizard at the bottom screen, guiding you swiftly and easily through all the required steps without missing anything. Additionally there are helpful mouse-over hints available for each parameter in the software, as well as additional notes in the [Help] menu.
FLYING IN ! It is mandatory to have tested all sensor directions! (page 7, point 2) ! First fl y with considerably reduced gain settings for tail and head gyro (40% recommended). ! Control test before every take off. Never take off before the servos can be moved. Only if servos are moving, the initialisation was successfull. PAY ATTENTION DURING TAKEOFF ! Generally pay attention to the horizontal position of the swashplate.
TAIL GYRO OPTIMISATION SENSITIVITY (GAIN) SETTING As usual, set the gyro gain as high as possible, at which the tail does not yet tend to oscillate, not even at high fl ight speed. The tendency to oscillate and thus the holding force crucially depend on the speed of the tail servo, but also on a play-free and easy-moving linkage as well as an optimum drive (no belt slipping, no breakdown of the motor controller at full coll.pitch, etc.).
HEAD GYRO OPTIMIZATION The attitude stabilisation („head gyro“) for the rigid linkage maintains any pilot-operated attitude and prevents disturbances, like e.g. ballooning. On ground, the function is visible at the swashplate: when giving control commands and let go off the stick, the swash moves slowly back to level, maybe even stays in the inclined position for a short while.
PA RT I C U L A R F EATU RE S O F THE 3S X As long as the functions of the [Horizon] menu are not activated, the 3SX’s function is identical to the 3X’s function. SETTING UP THE HORIZONTAL STABILIZATION Important: The 3SX does not allow „exceptions“...

HORIZON MENU Select the desired mode of operation using the parameter “self-leveling mode”. Beyond that, there are several ‘Advanced’ options available, which are precisely explained in the tool-tips (mouse-over) and that can usually be kept untouched. Following you will fi nd all explanation of the different options: 1 [hover &...
AUTOMATIC COLL. PITCH The automatic c.pitch action of the rescue features (2b) and (3b) overrides the pilot‘s c.pitch commands more and more with increasing gain setting at the Hor.-Channel. A signal of -100% (according to [Diagnose] menu) completely overrides the x.pitch stick commands, which is the highly recommended setup. Furthermore, the rescue mode should be triggered only by a spring loaded momentum switch, so that the pilot re-gains full control by releasing the switch.

AILERON TRAVEL For optimal response of the tail gyro, it is useful to set maximum possible aileron travel. The more aileron travel in the Mixer page, the more is available for the tail gyro as the limit for aileron and tail is the same. Due to the high torque produced by a tandem helicopter it requires a lot of travel to control this. If the helicopter reacts too agile due to the high aileron travel, you can reduce this within the Rigid page using the Agility setting or also with Expo / DualRate setting in the transmitter.
