Specifications:, Features:, Programmable Items:, Ø, Brake Setting:, Enabled / Disabled, default is disabled, Battery Type:, Li-xx (Li-ion or Li-poly) / Ni-xx (Ni-MH or NiCd), default is Li-xx., :, Soft Cut-Off (Gradually, :Low / Medium /, 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., battery, low / medium / high cut off voltage for each cell is:, .6V/2.85V/3.1V. When the voltage of any cell in battery pack is lower, Startup Mode:, Normal / Soft /Super-Soft, default is Normal., Timing:, Low / Medium / High, default is Low.

Net
Speed controllers for brushless motors are designed for best results
with any type of motors and accumulators.
Suitable for all types of accumulators NiCd, Nimh, Li- polymer,
Li-Ion.
High frequency brake with non linear course and limited braking action
Auto calibrating type with variable end point
Cut off type - slow down system with safety rest of accumulator’s capacity
Modelers will enjoy extremely low (.013 ohms) resistance combined
with high rate (8 kHz) switching.
BEC provides power to the receiver and servos, eliminating the need
for a separate receiver battery.

on the Guard series ESC, the ESC only monitors the voltage of the whole battery pack)

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%

When using balance discharge monitoring and protection function(i.e.
Plugging the balance charge connector on battery pack into the BDMP
socket on the Guard series ESC, the ESC monitors not only the voltage
of the whole battery pack but also the voltage of each cell). For lithium

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.
Ø
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.
