In case you’re still curious where those 4x16 Plates came from, I’m almost positive we only offer those in red in the VEX Robotics Tombstone
All of the HEXBUG VEX kits are designed by VEX engineers, and we generally try to throw a few extra useful parts in the kits for competition teams as well. While the electronic components in the kits like Build Blitz or Bite Force aren’t legal, nearly all VEX retail plastic components are VIQC legal.
