the servos that raise the swash plate on my e-razor won't move up and down any more to increase and decrease the throttle. does anyone know what could be wrong? I've been looking for a new receiver for it but can't seem to locate one.

Do they move at all? Did you toggle the gear switch after the heli was binded?

Did you install the servos? Was it like this when you got it?

If they move but only a little bit it almost sounds likethe servos aren't getting full travel. You can try to reset them to 90 degrees to the servo body. Disconnect the motor!!!Take the servo arms off and bind the heli. When its binded now you can reinstall the arms but install them so the arms are 90 degrees to the servo body.
