I was wondering what the ruling on the use of pneumatics in vexU is because it is not specifically mentioned in the vexU rules.
In this case, the statement at the beginning of the VEX U Appendix applies:
There are no modifications regarding pneumatics, which means that the rules from the standard In the Zone Game Manual apply (specifically <R7g>, <R7l>, <R15>, <R17>, and <R18>).
Edit: This answer was modified after posting to remove the mention of <R11>, which is overruled in VEX U by . We apologize for any confusion this may have caused.
