Basic Info.
Product Description

weight: 18g
programmable brief introduce:
1. brake setting: enabled / disabled, default is disabled
2. battery type: li-xx(li-ion or li-poly) / ni-xx(nimh or nicd),default is li-xx.
3. low voltage protection mode(cut-off mode): soft cut-off (gradually reduce the output power) or cut-off (immediately stop the output power). default is soft cut-off.
4. low voltage protection threshold(cut-off threshold): low / medium / high, default is medium.
1) for lithium batteries, the number of battery cells is calculated automatically. low / medium / high cutoff voltage for each cell is: 2.6v/2.85v/3.1v. for example: for a 3 cells lithium pack, when “medium†cutoff threshold is set, the cut-off voltage will be: 2.85*3=8.55v.
2) for nickel batteries, low / medium / high cutoff voltages are 0%/45%/60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. for example: for a 10 cells nimh battery, fully charged voltage is 1.44*6=8.64v, when “medium†cut-off threshold is set, the cut-off voltage will be:8.64*50%=4.3v.
5. startup mode: normal /soft /super-soft, default is normal.
normal is preferred for fixed-wing aircraft. soft or super-soft are preferred for helicopters. the initial acceleration of the soft and super-soft modes are slower in comparison, usually taking 1 second for soft startup or 2 seconds for super-soft startup from initial throttle advance to full throttle. if the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. this special design is very suitable for aerobatic flight when quick throttle response is needed.
6. timing: low / medium / high, default is low.
usually, low timing value can be used for most motors. we recommend the low timing value for 2 poles motor and medium timing value for motors with more than 6 poles to get a high efficiency. for higher speed, high timing value can be chosen
