With this latest generation system, the AXON increases the existing performance to a new level, not only in regards to the additional horizon and rescue features, but with the enhanced overall feature and characteristic set.

Page 4: Quick Introduction
SERVO ENUMERATION The following diagrams show the enumeration of the servos, and thus the correlation in connecting them to the AXON, dependent on the swash type. Note: 3-servo swash types may have the center servo linkage located either to the front or rear of the main shaft. The servo enumeration remains the same: #1 is left, #2 is right, and #3 is center. -
Page 5: Connection
CONNECTION VIA CABLE LOOM (STANDARD RECEIVER, PWM SIGNALS) Connect each cable of the cable loom to the appropriate channel on the receiver, accor- ding to the diagram. Example: Yellow cable Rx port for tail servo Connect servos to ports 1-5. Throttle/ESC stays with the Rx. Leave unused channels unplugged. -
Page 6: Led Display
• Never use the governor port to supply power to the system! It could take severe damage. • Do not connect servos until the device has been set to the correct servo type via software. • Do not move the model/device for the first few seconds after powering on (LED flashes red). The system runs a self-test and needs standstill to perform this, as otherwise it will not initialize, activate the servos, and start to flash 3x red power-cycle. -
Page 7: Setup / Adjustment
SETUP / ADJUSTMENT After installation, the device must be tuned to both the helicopter and transmitter, which first includes adaptation of the transmitter to the system, followed by setting up the system to the model. The software includes a setup wizard guiding you swiftly and easily through all the required steps without missing any. -
Page 8: Tuning
BANK SWITCH ING The AXON includes the option of up to 3 banks of different parameter sets. This means that not only can head gain and tail gain be adapted from the radio, but complete parameter sets can be defined and accessed via the head gain channel’s position. This includes all parameters from the HEAD/TAIL menu, and also the governor’s gain control (separate bank buttons for the two menus). -
Page 9: Tai Gyro Optimization
TAIL GYRO OPTIMIZATION SENSITIVITY (GAIN) SETTING As usual, set the gyro gain as high as possible, at which point the tail does not yet tend to oscillate, not even at high flight speed. The tendency to oscillate, and thus the holding force, mainly depends on the speed of the tail servo, but also on a mechanism free of play, with an easy moving linkage, as well as an optimum drive (without belt slipping, or breakdown of the motor controller at full coll.pitch, etc.). -
Page 10: Head Gyro Optimization
HEA D GY RO OP TI MIZAT I O N The attitude stabilization („head gyro“) for the flybarless head maintains any attitude and prevents disturbances, such as ballooning, if the pilot does not apply any further control input. On the ground, the function is visible on the swashplate: when giving control input and subsequently letting go of the stick, the swash moves slowly back to level, maybe even staying in the controlled position for a short moment. -
Page 11: Trimming / Failsafe
T RI MMING Using an electronic head stabilization, trim adjustment on the transmitter is not allowed (and not necessary). The system interprets any trim as a control input. Helicopters equipped with flybar, even though they would not need an electronic head stabilization, can still use it in order to correct any minor trim differences and drifts. -

S PEC IAL FE AT URE S HORI ZON AN D RE SC UE O P TIO NS Important: no exceptions are allowed regarding the setup of Horizon and Rescue modes, in particular: • The coll.pitch travel must reach its 100% marks as displayed in the DIAGNOSE menu, positive and negative, with correct signal direction. - Page 13 HORIZON/RESCUE MENU Select the desired mode of operation using the ‘Horizon Options’. ‘Rescue Climb Rate’ defines the climb speed in Rescue modes. The higher this value, the more coll.pitch is applied for rescue (only available for ‚Acro‘ and ‚Upright‘). Explaining the options: 1 [SCALE] LED green = ON, red/yellow/blue = OFF Not suitable for 3D flying and allowed only for helicopters which, due to their coll.pitch range (asym- metric), are not capable of inverted flight.
- Page 14 AUTOMATIC COLL.PITCH The automatic coll.pitch action of the rescue feature overrides the coll.pitch stick commands more and more with increasing gain setting on the Horizon channel. A signal of -100% (according to DIAGNOSE menu) completely overrides the coll.pitch stick, which is the highly recommended setup.

Page 15: Governor
GOV ERNOR The AXON includes an internal governor, suitable for electric and gasser/nitro use, which takes over the rpm control from the external governors/ESCm and is able to do this with high efficiency due to additional information about the current flight status. - Page 16 Example for gasser/nitro Connect the rpm sensor of your choice to the AXON‘s governor port. Make sure to get the polarity correct (according to the labling on the housing, ground facing to the outside). Throttle curve setup Illustration Idle1 At least 2 throttle curves are needed, one for running idle on the ground, as well as one each per flight setup.

Page 17: Vibration Analysis
VIBRATIO N AN A LYSI S This page shows the result of the vibration analysis, divided into head, tail and motor sections. If all sections are green, no critical vibration has been detected. If critical vibration is detected, the section with the highest vibration will be marked first. Example: Tail and head have too high a level of vibration, but the tail is worse. -

APP ENDIX TROUBLESHOOTING SERVOS DO NOT RUN AND LED FLASHES RED See chapter LED FINE MOVEMENTS WITH DIGITAL SERVOS ARE HEARD No problem, these result from the control loop, made audible by modern super-fast servos. JERKINESS OF TAIL SERVO If the tail gyro‘s auxiliary channel is at neutral position, it will stay around the switching point between heading hold and normal mode, and may randomly switch it on and off. - Page 19 The content of this document can be amended or adapted without prior announcement.
