Connecting The Transmitter & Receiver

A. Connect Radio Control System 

We are using the GooLRC - Radio Contol (2.4Ghz). 

Have your teacher provide you with a matching controller and receiver. Your teacher in advance will sync the transmitter and receiver and mark them with a matching color. Here are my NOTES for syncing the Transmitter and Receiver - students can ignore these notes. 

Insert 4 AA batteries into the transmitter. Solid Green is Good! Flashing Green...replace the batteries. Turn the transmitter's power off. 

B. Connecting the RC Car to the Transmitter/Receiver: 

  1. Turn everything off. Remove the Match Line and Power Line. 
  2. Insert the Servo line in Ch 1 - Orange wire to the left. 
  3. Insert the Power line in Ch 2 - White line to the left. 
  4. Turn the Transmitter and RC Power button on and squeeze the throttle...it should work...I hope! 

Note: If the wheels spin while off the ground, but your car does not move while on the ground...give it a little nudge with your toe...it should go! 

C. Modifying Your Car Performance Using The Transmitter 

  • Steering Trim (Ch 1/knob): Allows the user to adjust the steering wheel alignment. It will help you help your car to track in a straight line and not pull to one side. Hint: Drive your car on a flat surface at a low speed - now turn the "ST Trim" knob to make adjustments. 
  • Throttle Trim (Ch 2/knob): Allows the user to adjust the rear wheel. The Throttle Trim is not useful for Electric vehicles like ours, just gas powered cars, so keep the knob in the neutral position. Note: If your car has steering but no Throttle power to drive, most likely the Throttle Trim knob has been turned. Slowly turn the knob while pressing the Throttle and the power to the rear wheels will return. 
  • Steering Rate: Allows you to adjust the Servo Arm to travel to positions that are useful, not the full 120 degrees allowed. If you adjust it to far, it can restrict you from steering, Just keep it in neutral. 
  • 'ST' Switch (steering): "N" (neutral) - when you turn the Steering Wheel counter clockwise, the car will turn left. "R" (reverse) - when you turn the Steering Wheel clockwise, the car will turn right. 
  • "TH" Switch (throttle/power) - "N" (neutral) - when you press the Throttle, the car will drive straight. "R" (reverse) - when you press the Throttle, the car will drive backwards. If the wheels are moving in the wrong direction, just switch how the cables connect between the motor and the Power Transformer. 
  • "TH Limit" - Increases or decreases the speed: "L" = low, "M"= medium, "H"=high. 

D. My Transmitter Settings Recommendations: 

  • "TH Limit" = "L" 
  • "ST" = "N" 
  • "TH" = "N" 
  • "ST TRIM": Adjust till wheels are straight. 
  • "TH TRIM": neutral 
  • "ST RATE": neutral
