Feature:
• Adopting high performance 32-bit M4 microprocessor with a running frequency of 170MHz, supported much stronger computing ability and faster running speed.
• Adopting new generation craft on the MOSFET, low heat generation, large instantly withstand current, and high reliability.
• Self-check function: after the ESC powered on, it will automatically check if have the power short circuit ,motor lose phase, throttle is not at zero position problem, and voltage range.
• The special ESC case design and the unique fan guard structure greatly enhance the ESC heat dissipation performance.
• There are two flight modes: fixed-wing mode and helicopter mode.
• Equipped with the helicopter speed-control function, the speed sensitivity is adjustable and easy to operate.
• Equipped with the time selection function for stall landing, it can be manually adjustable within the time set to avoid a crash due to handling errors.
• The ESC has a separate programming interface to connect with LCD programming card or Bluetooth module for programming.
• Supporting data returning function: current, voltage, temperature, RPM, throttle and ESC status code.
• Bluetooth module supported, change the parameter settings, software upgrading, data recording and the operation can be completed via the mobile phone (Apple and Android) APP.
• Multiple protections: abnormal power-on voltage protection, start up protection, temperature protection,throttle signal loss protection, over load protection,low voltage protection, over current protection.
