Need help for Toy Remote Control Car Circuit

Circuit Maker · Jul 9, 2014

Hello everybody,
I want to make the following circuit but I can't find the RF Circuit. The typical application diagram needs a 27 Mhz crystal and I cant find it.

I looked at the following circuit too to slightly modify it for my purpose but it contains the 27 Mhz.

The IR circuit also works but it needs an IR Receiver circuit. Can somebody please give me one.
Also I would like to know why it needs 2 photo diodes.

Are those simple old Chinese remote control ICs still available?
I haven't seen a radio controlled product use 27MHz for about 30 years and all the infrared toy helicopters use more than one IR LED so the beam can be wider and more powerful.

I dont know whether they are available, I just found the circuit in the above site. But can you give the circuit diagram for an another remote control circuit with more available components.

Radio control transmitters and receivers are inexpensive and are available in hobby stores. Mine operate at 2.4GHz and the servos are proportional, not simply maximum movement then no movement.

The trouble is that they are hard to find in my country and has to be shipped so they become expensive. But I found some ICs on this site.

Now I have to find some circuits for these ICs.
