Help! Esc beeping rapidly when throttle and has only one beep at startup.

[Yash0103]

i recently purchased simonk 30amp esc. As I was new to rc i didn't knew I have to calibrate it, and directly used joystick code with Arduino.

Initially the motor worked fine, but while fixing the calibration, I think I i did some mistake in code, it stopped working completely. Now when I throttle, the motor doesn't rotate and vibrates and esc keeps beeping rapidly, so am not able to calibrate it and or enter programming mode to reset the esc.

Also when connecting 3s battery to esc earlier there were 3 beeps at startup, but now only one.

...Now when I throttle, the motor doesn't rotate and vibrates ...

When a motor jitters, it usually indicates one of the three motor windings is not getting power. It could be a bad solder joint, a broken wire, some kind of short or a bad ESC. The first thing to try is, gently tug on each of the 3 wires to see if you have a bad solder joint. Tug on the ESC, motor & bullet connectors. If there is a bad joint the wire will come off very easily, it's held only by the heat shrink.

Have you tried holding the throttle at 100% when you plugged it in, and when it beeps lowering it down to 0%?

How much time should it beep? Then the full throttle. What if you place in a wrong lower size watt battery? Will the throttle go slowly or not at all.
What is the red, and yellow, and blinking orange light mean? I didn’t think this rc airplane have brains. Buy the wrong size lower and it won’t go on or just slowly. They didn’t give me any instructions on Flysky 4 channel when ordered it in 2021.

I’m not sure now. On my next setup, I’ll set it up on site. That way it’s ready to go. If I shut if off the radio, the whole setup won’t work again. I didn’t read many articles on RC control airplanes. But just on what I see, setting things up requires correct sequence. Already I saw several mistakes going over my head on what to do. Like touch the propeller while setting the ESC and placing it in. A person can die just by mistakes. I’m usually a careful person. So I’m doing this slowly and carefully.

I think it is awesome they have ”local brahs” who like to do RC model Airplanes. Hobby goers. Just buy a ready made one, and set. Just that not the correct airplane I want flying. I guess you guys are paying for a YouTube account too. For the short 15 minute videos on How to make?
