Operation Description The transmitter operates at 49.860MHz, which is controlled by a crystal. It is powered by 9V battery. There are two-control key on the transmitter. When the forward control trigger is pushed/pulled once, a radio frequency will be transmitted for the receiver for going forward/backward. When the direction control steering wheel is turned the left/right once, a radio frequency will be transmitted for the receiver for going left/right. Refer to the transmitter circuit design, the circuit description is listed below:
 U2 and associate circuit act as encoder
 Y1 and associate circuit act as oscillator
Q1, Q2 and associate circuit act as RF amplifier
 C10, C11, L4 and associate circuit act as low pass filter
