triven:
i want to connect these outputs(4 of them) to my arduino inputs.
You're referring to 'spring switches' in the control unit. The picture seems to show a couple of joysticks. I guess they are single axis joysticks - this configuration is typical for two-channel remote control systems. On cheap models each joystick may just be connected to a couple of limit switches, but more usually each joystick will be connected to a single potentiometer which can be used to give you an output voltage proportional to the joystick's position. Which type do you have?
