5. Timing setup: Automatic / Low / High.
* Automatic – ESC automatically determines the optimum motor timing
* Low (7-22 deg) – Setting for most 2 pole motors.
* High (22-30 deg)-setting for motors with 6 or more poles.
In most cases, automatic timing works well for all types of motors. However for high efficiency we
recommend the Low timing setting for 2 pole motors (general in-runners) and high timing for 6 poles
and above (general outrunners). For higher speed, High timing can be set. Some motors require
different timing setups therefore we suggest you follow the manufacturer recommended setup or use
the automatic timing setting if you are unsure.
Note: Run your motor on the ground first after making any changes to your motor timing!
6. Soft Acceleration Start ups: Very Soft / Soft Acceleration/ Start Acceleration
* Very Soft – Provides initial slow 1.5 sec ramp-up from start to full rpm intended to protect delicate
gears from stripping under instant load. This setting is recommended for either fixed wing models
equipped with gearboxes and / or helicopters.
* Soft Acceleration- Provides initial slow 1 sec ramp-up from start to full rpm. This setting is recom-
mended for either fixed wing models equipped with gearboxes and or helicopters.
* Start Acceleration – Provides quick acceleration start ups with a linear throttle response. This is
recommended for fixed wing models fitted with direct drive setups.
7. Active RPM Control (Heli Governor Mode)
* RPM control off
* First range: There will be a 5-second delay from start to full rpm, but if the throttle is cut off after
starting, then the next start will be as normal start.
* Second range: There will be a 15-second delay from start to full rpm, but if the throttle is cut off after
starting, then the next start will be as normal start.
Note: Once the Governor Mode is enabled, the ESC’s Brake and Low Voltage Cutoff Type settings will
automatically be reset to No Brake and Reduce Power respectively regardless of what settings they
were previously set as.
8. Motor Rotation: Reverse
In most cases motor rotation is usually reversed by swapping two motor wires. However, in cases
where the motor cables have been directly soldered to the ESC cables, motor rotation can be
reversed by changing the value of setting on the ESC.
9. Switching Frequency: 8 kHz/16kHz
* 8 kHz – Sets ESC switching frequency for 2 pole motors, e.g. in-runners.
* 16 kHz – Sets ESC switching frequency for motors with more than 2 poles, e.g. out-runners.
Although 16 kHz is more efficient with our Thrust motors, the setup
default is 8 kHz due to the higher RF noises caused at 16 kHz.
10. Low Voltage Cutoff Type: Reduce Power / Hard cutoff
* Reduce Power – ESC reduces motor power when the pre-set (recommended).
* Hard Cutoff – ESC instantly cuts motor power when the pre-set Low Voltage Protection Threshold
value is reached.
