<R19> Rule R 19 lists several Non-VEX components that are allowed. In previous years, both the manual and the knowledgebase listed the specific SMC legacy pneumatics components that were legal for competition use. This year there is no mention of the legacy pneumatics in the manual at all. They are not listed as allowed parts in R 19, but there is also no mention of them not being allowed in R 18, so there is a bit of confusion. Several other rules in the manual (GG3, R25, R26, etc) specifically mention VEX pneumatics parts. Am I correct to assume that this means that the legacy SMC pneumatics components are not legal to use this year and the only legal pneumatic components are the VEX branded ones?
