Why Can't Pair Remote to Maytech 300A ESC Even if All Connections and Steps Are Correct?
If can't pair MTSKR1905WF remote with our 300A ESC successfully, might has below reasons:
1. Please check if the receiver or ESC power (Internal receiver version) is always on. Before pairing, please make sure the receiver power or ESC (Internal receiver version) power is off first, then turn on the remote screen and "Pair" in main menu until 【Pairing...】shows on the screen, and then turn on the receiver or ESC (internal receiver version) power, remote will pair automatically in about 0.5 seconds.
2. Some customers all above pairing steps are correct, but still can't pair successfully, Why?
Our 300A ESC requires at least 18V voltage so can power up, and our waterproof 300A ESC version has built-in DC-DC UBEC (18-75V Convert to 5V), so if you use voltage under 18V, the ESC can't work properly.
If you use our remote to other ESC and can't power successfully, please check below reasons:
1. Please check if your ESC is with BEC or not, if not, please connect 5V UBEC, if yes, then check if your UBEC is 5V output or not.
2. If UBEC voltage is correct, please check if your connection is correct or not, you can refer to below wiring diagram:
