My drone wont arm

[hobbyczar]

Running emuflight and ive had people look at it no one can figure it out. Beta flight controller with crossfire module. drone has crossfire nano rx. Light is green its defintly binded. None of the buttons will arm the drone. In emu flight it shoes the drone is level and on the beta flight config is shows the controller throttle is all the way down. Im a noob so i dont konw what else to try. Heliosprings flight controller. Everything functions fine the controller works on a sim. I think it has a beeper to but it wont turn on.
