Bidirectional 1:1 power output, no brake,direct reverse, quick response, good handling. No need to calibrate throttle stroke, plug and play. All products contain UBEC output. Note: 1. When using, the remote control throttle remote lever must be in the middle position, otherwise it cannot start. 2. There is no need to calibrate the throttle stroke. When the electric adjustment is started, if the motor starts to rotate, you can use the remote control to fine-tune the throttle to stop the motor. Package include: 1 x 50A Bidirectional ESC

Review: Muy buen control de velocidad. - Muy buen control de velocidad, arranque y precisión. Lo uso en unos Rc echos de hoverboard y aguantan muchísimo.
Review: Good value - I use these to run some cheapo a2212 brushless motors on arduino and esp32 Note to buyer doing the same, 1100 is your minimum for movement, 2000 is your max. Go opposite to reverse. Max pulse -2000 to 2000, 0 to stop, anything in the 0 to 1100 ranges will give some power, but the motor stalls, you can probably use that to slow down after acceleration

### ⭐⭐⭐⭐⭐ Excellent Bidirectional ESC! Just what I was looking for!
*by P***6 on 26 July 2022*

I used this ESC with the following motors: https://smile.amazon.com/dp/B07545RQ62 https://smile.amazon.com/dp/B07JG1LKYQ It work perfectly with Raspberry Pi, ESC requires the PWM signal to be right in the middle and the response is quick! No clogging! I've also tested this with Arduino and a Servo tester, no issues. One thing to keep in mind, you need to have good connections to the motor, I tried using small jumper cables and that caused alot of clogging. Make sure you have the right connectors or solder it on.
