AR-7A 5.5g Mini Size 7A Brushless Electronic Speed Controller 2S RC Helicopter Airplane ESC With UBEC
Application:RC Airplane, Helicopter, Quadcopter
Item Name: AR-7A
Constant Current: 6A
Peak Current: 10A
Input Voltage: 2s lipo
Ultra-low impedance PCB(printed circuit board) and high power MOS drive tube with independent cooling fin for great current endurance.
Power input with ultra low impedance and large volume capacitor to improve the power stability and protect the battery.
Safety to power on. While power on, no matter how you operate the throttle stick, the motor do not start immediately to avoid personal injuries.
Multiple protection: Input Voltage Abnormality Protection, Low Voltage Battery Protection, Overheat Protection, Throttle Signal Loss Protection etc., which extend effectively the lifespan of ESC.
Three start mode: regular start, soft start and super soft start, which compatible with fixed wing aircraft and helicopter.
Programmable throttle curve suitable for all kinds of remote controllers. Smooth and exquisite speed regulation, perfect speed linear.
Microprocessor power supply with independent stabilized voltage IC, superior anti-interence to reduce te possibility of out-of-control.
The maximum rotation speed can up to 210000RPM (2 poles motor), 70000RPM ( 6 poles motor), 35000RPM (12 poles motor).
