• BEC Voltage - Select the BEC output voltage. Default and available settings per ESC.
• Start-up Mode
o Normal Start-up: If this mode is selected, the motor will immediately increase in RPM to
correspond to the throttle stick input.
o Soft Start-up: If this mode is selected, the motor will gradually increase in RPM to
correspond to the throttle stick input.
TIP: We recommend using this soft start-up mode when using large diameter motors or
gear drives.
• Timing - Select Low, Medium, or High motor timing.
• Motor Rotation - Adjust the rotation direction of the motor without changing wires.
• Active Freewheeling - This option can be set to Enabled or Disabled. Freewheeling can help provide
better throttle linearity or smoother throttle response.
GOVERNOR SETUP
If the governor mode is activated, the ESC will try its best to hold the rotor head speed at a fixed value
that you assign. In order for your Avian ESC to calculate the speed of the main rotor blades of your
helicopter, you need to know the motor poles number and the gear ratio of main drive gear vs. the
pinion. Below is an example of this screen with an Avian 100 setup for a Blade Fusion 480 model running
a 14 pole motor, 11 tooth pinion and 112 tooth main gear.
When you adjust the throttle curve, please make sure that the motor can run at this preset speed even
if the motor load is heaviest. Please note that the governor mode function is automatically disabled if
the throttle volume is less than 60% or more than 90% to allow for proper motor control in high and low
load scenarios.
