OGM17039TX-4949 MHz R/C Super Roadster

Operation Description 17039 (49M) Super Roadster 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 trigger is pushed 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:
 IC1 and associate circuit act as encoder
 Q1 and TX1 and associate circuit act as oscillator
Q2 and associate circuit act as amplifier
 D9 and associate circuit act as voltage readjustment
