Operation Description R/C Micro Hauler Charger (49MHz) The R/C Micro Hauler Charger (49MHz) is powered by 9V battery and operated at 49.860MHz which controlled by crystal. There are two- control key in the front of the transmitter. When the speed control key pressed once, it will transmit a radio frequency for receiver going forward or backward. When the steering wheel turned once, it will transmit a radio frequency for receiver turn left or right. Refer to the transmitter circuit design, the circuit description is listed as below:
U1 and associate circuit act as encoder.
 D2 and associate circuit act as voltage regulator.
 Q4 and associate circuit act as amplifier.
 Q1, Q2 and associate circuit act as voltage control.
 Q3, X1 and associate circuit act as Oscillator.
 LED2 - LED5 and associate circuit act as LED L/R/B/F.
