How would I control a JCarousel inside another JCarousel?

How do I get a 49 mhz controller from one remote control car to work with a 49 mhz car from another kit?

• Okay, I have a 49 mhz remote control car with no controller, so I went out and bought a cheap remote control car that has a 49 mhz remote controller. How do I get the controller to work with the other car? You would think it would automatically work because they are on the same frequency. It doesn't. Also, the controller and the car are not from the same company, but it should not make a difference, should it?

• Answer:

  Oooook. Short answer, is you can't. Long answer is; Each remote car, and remote car radio handset has a crystal in it. The crystal in the remote car, and the handset it came with are identical, producing the same frequency and running your car. However, the cheap remote car radio handset your purchased has a very slightly different crystal, it is still 49mhz, but it may be 49.174 while the one you had before was 49.566. Basically this means that you wont be able to get control of the car with a different handset. However, hobby grade cars have the crystals visibly on the outside of the radio handset. IF this is the case, you can remove the crystal from the handset, and switch it with another. Same with the car, IF ITS HOBBYGRADE you can take the top of, the crystal will be poking out of a small black box, the reciever. IF this is the case, you can swap the crystals around. However if what you've got is two toys cars, im sorry to say it, your stuffed. If you need more info, see http://en.wikipedia.org/wiki/Remote_control_car#Toy-grade_radio_control
