I have just built a simple bot and need RF control (like for a race car). All I need to control is the motion of the motor. Where would I be able to find a schmatic on this? I just took apart 2 old childrens walki-talkis and retrieved 2 45 mhz. crystals from them. Would I be able to use these at all? I am a complete beginner on RF control.<p> ====Matt====

Matt,
I would suggest you get a radio control car and use that for your robot. You get both the radio and the reciever there. The radios you have torn apart will not help you.<p>The basic system is: pot to radio to receiver to servo to motor. Radio contains the pot. <p>Use the car receiver and servo (if there is one) in your robot.
