My robot will only respond when I am 20ft or closer to it, any farther and it doesn’t work. I didnt know if that is normal but I don’t think it is. I have the vex power pack and they were both fully charged, the antena was all th way out an parallel to the robot’s antena, but it still won’t go very far! any help you could give me would help.
See if you can try a different Receiver and/or Transmitter. Make sure your antenna is not shielded in your robot. Also try a different frequency crystals and/or move to a different location.
