Why do the swashplate servos run very slowly when testing on the bench?

This is absolutely normal. The movement of the stick gives AR7200BX/AR7210BX/AR7300BX only a command to control the helicopter. The sticks do no longer control the servos directly. So you cannot say exactly what AR7200BX/AR7210BX/AR7300BX will do with the servos when you push one of the sticks.
