20A 30A 40A 50A 60A 80A Brushless Speed Controller ESC BEC for RC Airplane Quadcopter Helicopter

20A1. Output capacity: continuous current 20A, short-time current 25A (not less than 10 seconds);2. Power input: 2-3 lithium battery packs or 5-9 nickel-metal hydride/nickel-cadmium battery packs;3. BEC output: 5V2A (linear regulator mode – linear mode);4. Maximum speed: 210,000 rpm for 2-pole motor, 7000 rpm for 6-pole motor and 35,000 rpm for 12-pole motor;5. Size: 42mm (length) * 25mm (width) * 8mm (height);Use common sense:- Some players pick up the electrical directly loaded on the plane, the result is to hear the beep sound, the motor is not turn, or speed up, for the following reasons:- The first time you use the ESC to identify the maximum travel and minimum travel of the remote control, as follows:- The ESC and the motor connected — ESC line connected to the receiver —- open the remote control and push the throttle to the highest point —- the ESC plug in the battery —- listen to the sound —- beep – beep —- three after the throttle stick pulled to the lowest point —- hear the beep three sound —- OK- Brushless three-line can be arbitrarily connected, if the steering is wrong, to any of the two lines on the tune about itures:- Brake setting: no brakes / brakes;- Battery type: lithium battery / nickel hydrogen;- Low voltage protection mode: soft shutdown / hard shutdown;- Low voltage protection threshold: low / medium / high;- Start mode: normal / soft / super soft start;- Angle: low / medium / high;- Restore factory defaults;
