The new text of section 4.4 is as follows:
4.4. Plastic Classes. The spirit of these classes is to have an easy entry point for new builders and to encourage creative designs by limiting materials to plastics that are easy to work with, commonly used in 3D printers and don’t have strength characteristics common in the standard classes.
4.4.1. PET, PETG, ABS, PLA, or PLA+ are the only materials that can be used for the chassis and weapons. No other types of plastics or materials allowed (ie. metal, carbon fiber, UHMW, etc). At their discretion, event organizers may allow additional plastics that meet the spirit of the rules.
4.4.2. Non-plastic parts such as motors, electronics, axles, fasteners and adhesives can be any material, but cannot be used in such a way to enhance the structural integrity, armor the robot, or enhance any weapon. Magnets to enhance traction or downforce are prohibited. Foam is allowed for wheels and padding of electronics.
4.4.3. Robots may be disqualified at the Event Organizer’s discretion if it is deemed to violate the spirit of the class. Contact the event organizer ahead of time if you are not sure your robot meets the above definition.
