GR18 and MZ-12 Reset?

[Tank]

So I put together my Versacopter V2 and I think I messed up during the Calibrations and radio setup I and would like to redo it but I don't know how to reset the Gr18 and Mz-12. My problem it that the motors keep beeping nonstop and its not the startup beeping I have know Idea why and I can't throttle up or down it just keeps beeping. If anyone know's how to fix this or reset the radio that would be very helpful thank you!

EDIT!! I have found out that it is definitely my ESC because everything is hooked up correct, but now the the motor doesn't even beep now it just doesn't do anything the other 3 motors turn but one doesn't turn

Not familiar with Graupner gear, but I've had similar motor/ESC issues caused by dodgy solders. Check all your joins, visually and with a multimeter if possible!

I did that way before posting this everything is working just the motor doesn't spin when setup to the esc but if it is hooked up to any other one it works. But thanks for Helping!
