Connection Diagram :
Low-voltage soft cut-off protection, cause throttle
going slow down.
Battery range protection, when the voltage of the
battery pack is lower/higher than the Battery range
threshold, the alarm status is activated.
Brake / No-Brake operation. Stop folding props cold
or let fixed props freewheel.
Safe "power on" arming program ensures motor will
not accidentally turn on.
Low torque "soft start" prevents damage to fragile
gear boxes.
Auto shut down in 2sec. after when RX signal is lost
or radio interference becomes severe.
Throttle Range can be auto setting during at first
power on time.
ESC can make brushless motor play a music when
all the setting is ready to go.
Operation Produce:
1. Choose right Battery voltage range according to
ESC input range.
2. Automatic throttle adjustment for using on every
transmitter.
3. Setting Brake or Non-brake mode.
