Circuit Description

When the remote control forward, backward, left, right, each

function by pressing the corresponding encoding chip function pin

high level, after IC(TX2-4) internal A/D conversion circuit, reduction

of each function signal. After reduction each function signal, the IC

internal to encode their corresponding instructions, encoded output

PC and IC at the same time in the encoding of the output pin part

control high frequency oscillation output level work, high-frequency

oscillation signal and coding signal in some form of modulated

wave modulation circuit, output circuit, the antenna output.

The working frequency is 27.145MHz.
