1.Power-on security features: power-on, regardless of the throttle stick position, the motor will not start immediately,
to avoid making harm
2.Throttle Calibration function: remote control to adapt to differences between different throttle range,
improve the linearity of throttle response
1)Brake Settings: brake enabled / brake
2)Battery Type: Li-xx Lithium Battery Ni-xx (Ni-Cd or Ni-MH)
3)Low Voltage Protection; mode reduces power on / off output
4)Low Voltage Protection Threshold: Low / Medium / High
5)Start mode: Normal / Soft / Super-soft and starting
6)Timing: low / medium / high
7)restore factory defaults
4.Comprehensive protection functions:
1)under voltage protection: the program is set by the user when the battery voltage is below the protection threshold,
the ESC automatically reduces the output power
2)Overvoltage Protection: Input voltage exceeds the input range are not allowed to start, automatic protection,
also issued a hasty "beep beep" alarm sound
3)Overheat protection: Built-in temperature detection circuit, when the temperature is too high
power MOS pipe tune automatic shutdown
4)remote signal loss protection: remote control signal to reduce power after losing one second,
then there is no remote control signal is two seconds off the output
2.Hooray compatible technology produced Brushless ESC programmed card.
3.Gold-plated connectors provide motor and auxiliary heat shrink tubing, easy to install.
4.Ultra low power input impedance electrolytic bulk capacitor, which greatly improve anti-jamming capability.
5.Output power MOSFET with a separate heat sink, effectively reducing the device temperature, high current ability
to work to improve the system.
6.Chip micro controller using an independent regulator to avoid BEC load changes caused by power disturbances and
improve the stability of the micro controller.
