Throttle Servo Type - Select the option that matches the throttle servo or ESC. Once the correct option is selected the throttle servo can be plugged to the SV5 port of the Vortex. Before an ESC with BEC function is connected to the Vortex disconnect any other power source that was previously used during setup. Some ESCs may fail if external power is applied to their output.
Note on KBUG: The BEC in Kosmik ESCs shuts down and power cycles continuously if a throttle signal is not provided within a few seconds. However, some RC receivers do not always link fast enough. The KBUG option bypasses this issue by providing failsafe throttle level to the ESC until the receiver has linked. Ensure that you have programmed the Vortex's inbuilt failsafe to motor off when using this option.

Governor Type - When 'Inhibit' is selected the governor function is disabled and the transmitter throttle signal is channelled to the SV5 servo output. Select this option when using the governor inside your ESC.
Connect RPM Signal - Compatible Phase Sensors can be connected direct to the RPM port of the Vortex. Castle and HobbyWing ESCs with RPM output can be connected direct to the Vortex. If the RPM plug of the ESC has a middle/red wire this must be removed from the plug before it is connected to the Vortex. The RPM output of your ESC may need to be enabled by configuring the ESC. Scorpion ESCs require a Scorpion Opto-isolation cable between the ESC and the flybarless sysyem. Some YGE ESCs support RPM output. This usually requires an adapter lead between the ESC and the flybarless sysyem. Consult the ESC's user manual for details. More info: See knowledge base topic 151 on the Spartan website.

Connect RPM Sensor - We recommend using a Spartan RPM sensor (Part no: SRC-RPM or SRC-RPMK including engine mounting brackets) which is designed to work with your Vortex. Some 3rd party RPM sensors may also work. See knowledge base topic 151 on the Spartan website for details.

Motor Poles - Set the number of motor poles as stated by the motor manufacturer. This value must be exact and not a best guess as this would result to wrong head speed.
Sensing Magnets - Set the number of magnets on the engine fan, counting only the ones that activate the RPM sensor. If you are using RPM signal from the engine ignition system of a gasser set this to 1.
Gear Ratio - This is the gear ratio between the engine and the main rotor. If you are unable to find this information in the helicopter's user guide you can calculate it by dividing the number teeth of the main gear by the number of teeth of the pinion gear.
Auto Abort Detection - The inbuilt soft-start and autorotation abort functions of the Vortex are enabled by default. In order for them to operate correctly the equivalent functions of the ESC must be are turned off. If this is not possible the inbuilt soft-start and autorotation abort will need to be disabled via the Governor menu so the don't interfere with the equivalent functions of the ESC.
In order for the Vortex to recognise when autorotation abort is needed the transmitter's throttle hold parameter or H mode curve need to be set to a specific value. Adjust your transmitter so that 11% (+/-3%) is displayed at the bar. With this mechanism autorotation abort will activate when the throttle signal steps from hold to a higher value. Soft-start will activate when the throttle is below 7% and then increased above hold.
Throttle Servo Direction - Operate the throttle stick and observe the servo moves the correct way. Reverse as required. Most ESCs do not require reversing.
ESC Calibration - The throttle range of the Vortex and ESC need to be matched. This is necessary even if it was previously done with the ESC connected directly to the receiver or to the Vortex without using the governor. Follow the advice in the user guide of your ESC but when asked to adjust the radio system endpoints, adjust the throttle endpoints of the Vortex instead. There are two common paths which we summarise here:
1) Most ESCs are designed to match the throttle range of the radio system. Typically the stick is placed to full throttle and then the ESC is powered on. After the ESC emits a confirmation tone the the stick is pulled to the lowest position. The ESC emits one more confirmation tone and the process is complete. If the ESC does not emit confirmation tones the throttle endpoints of the Vortex may need to be adjusted to a higher value.
2) Some ESC use fixed endpoints which the radio system needs to match. Typically both max and idle throttle endpoints of the Vortex are reduced to 30%, the stick is placed at full throttle and then the ESC is powered on. The max throttle endpoint of the Vortex is slowly increased until the ESC emits a confirmation tone. The stick is then placed at the lowest point and the idle endpoint is slowly increased until a second confirmation tone is heard. The process is complete.
Throttle Max Endpoint - Adjust the throttle servo endpoint so the carburettor reaches the fully open position.
Throttle Idle Endpoint - Adjust the servo endpoint for the approximate idle position.
Complete - The throttle setup is now complete. Please proceed to the heli wizard.
Complete - Regardless if the helicopter is nitro, gasser or electric set the throttle curves of the Idle-1/2 to 100-60-100% or 90-50-90% for overpowered setups. Ideally the throttle curve should be tuned to roughly produce the desired rotor RPM however these recommended curves will usually suffice. The Vortex monitors the output of these curves to anticipate power demand.
Set the the throttle curve of the Normal flight mode to 0-50-100%. When the electric governor is used this will instruct the Vortex to do a soft-start when the throttle stick is raised above 15% or when switching from Normal to an Idle-Up.
If you wish to bench test the governor without blades lower parameter Minimum Throttle Limit in the Governor menu to 15%. The default value of this parameter works well in flight but it will cause overspeed when no blades are installed.
The throttle setup is now complete. Please proceed to the heli wizard.
