This Instructable will show you how to make a 2-channel remote control which you can use for your remote control helicopters!
For a multi channel remote control, you can use a CD4017 both in the transmitter and the receiver circuits.
You will need:
2 555 timer ICs
2 10uf Capacitors
2 10k resistors
3 1k resistors
2 10nf capacitors
5 BC547 transistors
2 1N4148 diodes
some wires
A breadboard(it is good to first prototype it)

Step 1: Clock circuit

This part uses:
555 timer IC
10uf Capacitor
10nf capacitor
10k resistor
1k resistor

The frequency of the circuit will be 11.99 Hz. If you want to increase the frequency, reduce the resistance and capacitance and you will be done

This circuit's diagram is not by me. It is from :
It will also have a calculator to calculate the frequency of the circuit.

Also you will need to build one more for the receiver.
