I have upgraded my radio system from a traxxas link system to an Airtronics MX-Sport. After I bound it the only thing not working was the speed controler. I have a castle Sidewinder SCT system.
The speed controller would just beep at me. I have tried repluging everything. I looked there is only one way for it to fit.

Thanks in advance

Have you calibrated the ESC to the new transmitter ?

Read the manual that came with the ESC or get it online, explains the process

Cheers

Ok Thanks will try that tonight
