Crystal Upgrade Kit B
This expansion pack allows you to change the frequency used by the transmitter to control the Vex autonomous robot. The transmitter included in the Dual Control Starter Bundle, uses a standard frequency for all kits. When you want to remote control Vex robots simultaneously using multiple transmitters, such as during a competition, it is necessary to change the frequency used by the transmitters so that each robot is controlled by a transmitter with its own frequency.
Crystal Upgrade Kit A from Vex Robotics has 4 pairs of crystals (the crystals are supplied in pairs, one for the robot and one for the transmitter) each offering a different frequency:
- Channel 63 (radio frequency 75,450 MHz)
- Channel 67 (radio frequency 75,530 MHz)
- Channel 83 (radio frequency 75,850 MHz)
- Channel 87 (radio frequency 75,930 MHz)
