Thankyou!! I tested the new one provided by ReadyToSky, and it works perfectly! I am grateful they responded so quickly to help my situation! I will try out the new ESC once I receive it, and update review accordingly. I wanted to like this, but I shorted out and almost started on fire the first time I tried to use it.

Just what I was looking for! - I used this ESC with the following motors: https://smile.desertcart.com/dp/B07545RQ62 https://smile.desertcart.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. ## Features - Bidirectional 50A 2-6s UBEC 5A 5V. - It can be used in cars, ships, underwater thrusters. - No need to calibrate throttle stroke, plug and play. - Bidirectional 1:1 power output, no brake,direct reverse, quick response, good handling. - Simple Manual: 1.Throttle stick must be in center or it will not start. 2.ESC no need to calibrate throttle range.
