GENERAL SETTINGS
• Flight Mode
o Fixed Wing (*)Default – For use with Aircraft and non-governed Heli models
o Helicopter – Enables the Speed governing “Govenor” mode for fixed RPM motor speeds
• Brake Type
o Disabled (*) Default – Motor will free wheel when throttle position is zero
o Normal – When throttle position is zero, the assigned brake force will be applied
o Proportional - With this option selected the throttle range changes so the ESC will not
start below 20%. The throttle will operate as normal above 20%, but moving the throttle
below 20% will apply the brakes, increasing in strength as the signal drops to 0%.
• Brake Force – This option is adjustable from level 0 (* Default) to level 7. The higher the level, the
stronger the braking effect. Brake Force is only effective in the “Normal brake” mode.
• Voltage Cutoff Type
o Soft Cutoff: Selecting this option will gradually reduce the ESC output to 50% of the full
power within 3 seconds after the low-voltage cutoff protection is activated.
o Hard Cutoff: Selecting this option will immediately cut off the ESC output when the low-
voltage cutoff protection is activated.
• LiPo Cells - Select Auto Calc to cause the ESC to automatically calculate the number of LiPo cells
based on a 3.7V/cell default. Alternatively, you can select a specific sell count to set the ESC to a
fixed battery configuration.
• Cutoff Voltage - Use this option to adjust the cutoff voltage from 2.8V to 3.8V/cell or disable the
cutoff voltage completely. 3.0v is the default WARNING: Discharging a LiPo battery below 2.8V/
cell may damage the battery. Attempting to charge or discharge a damaged battery can cause a
fire.
