OGM70049TX-27R/C RALLY RACER TWIN PACK (27MHz TX)

Operation Description 70049 27MHz R/C Rally Racer Twin Pack The transmitter operates at 27.145MHz which is controlled by a crystal. It is powered by 9V battery and it has two-control key on the transmitter. When the forward or backward control trigger is pushed / pulled once, a radio frequency will be transmitted for the receiver for going forward/backward. When the 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:
U1 and associate circuit act as encoder
Q2 and X1 and associate circuit act as oscillator
Q1 and associate circuit act as amplifier
