Settings: 
1.Brake: ON/OFF 

ON

- Sets the propeller to the brake position when the throttle stick 

is

 at the minimum position 

(Recommended for folding props). 

OFF

- Sets the propeller to freewheel when the throttle stick is at the minimum position. 

2.Battery type: LiPo or NiCad/NiMh

 

NiCad/NiMH

 – Sets Low Voltage protection threshold for NiCad/NiMH cells. 

LiPo

 – Sets Low voltage protection threshold for LiPo cells and automatically detects the number of 

cells within the pack. 
Note: Selecting the NiCad/NiMH option for the battery type, triggers the ESC to automatically set the 
cutoff threshold to the factory default of 60%. The cutoff threshold can then be subsequently altered 
through the Low Voltage protection function, if required. The ESC will read the initial voltage of the 
NiCad/NiMh pack once it is plugged in and the voltage read will then be used as a reference for the cutoff 
voltage threshold. 

3.Low Voltage Protection Threshold ( Cutoff Threshold ): 
Low / Medium / High 

1) For Li-xx packs- number of cells are automatically calculated and requires no user input apart from 
defining the battery type. This ESC provides 3 setting options for the low voltage protection threshold ; 
Low (2.8V)/ Medium (3.0V)/ High (3.2V). For example : the voltage cutoff options for an 11.1V/ 3 cell 
Li-Po pack would be 8.4V (Low)/ 9.0V(Med)/ 9.6V(High) 
2) For Ni-xx packs-low / medium / high cutoff voltages are 50%/60%/65% of the initial voltage of the 
battery pack.. For example: A fully charged 6 cell NiMh pack’s voltage is 1.44V x 6=8.64V,when “LOW” 
cutoff voltage is set, the cutoff voltage is: 8.64V x 50%=4.3V and when “Medium” of “High” is set, the 
cutoff voltage is now 8.64V X 65%=5.61V.

5.Timing Setup :    Automatic/ Low / High. 

 Automatic

 

(7-30 deg) 

– 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 out-runners). For higher speed, High timing can be set. Some motors require 
different timing setups therefore we suggest you to 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
