    "l. Commercially available items used solely for the purpose of bundling or wrapping of 2-wire, 3-wire, 4-wire cables, and pneumatic tubing, for the purposes of protection, organization, or management are allowed. This includes but is not limited to electrical tape, cable carrier, cable track, etc. Note: it is up to inspectors to determine whether a component is serving a function beyond protecting and managing cables."

    In your answer here, you seem to give a bit of a contradiction that is confusing at best.

    You make the point, though grammatically ambiguous, that the rule is solely for the purpose of "solely for the purpose of bundling or wrapping of 2-wire, 3-wire, 4-wire cables" and all clauses after that are subordinate clauses. It would seem, though, that this is a series given the commas and the use of "or" before the last clause.

    I must concede your interpretation but then you suggest something that seems to violate your own interpretation. You said "Electrical tape or shrink tubing may also be able to achieve this goal (especially if combined with strain relief technique described above)." The use of electric tape is subject to the same constraints and is even specifically mentioned. It would seem that if you can use electric tape for strain relief (purpose of protection) then hot glue or Sugru would also be just as legal to use.

    Given the construction quality of the Vex 393 motors, I would hope you would reconsider allowing these means to be used solely for the purpose of protection of the wires. Once the wires are pulled out of the motor, it is my understanding, based on previous year's Q&A that reconnecting them internally is not legal for VRC competition. If that has changed, that would be another way of helping teams deal with the high cost of replacing expensive motors that come apart all too easily.

    It would seem that if you can use electric tape for strain relief (purpose of protection) then hot glue or Sugru would also be just as legal to use.

    Electrical tape and shrink tubing are explicitly mentioned in R15ii. Hot glue is not, and R15ii does not include the "any commercially available product" verbiage found elsewhere in the manual.

    I would hope you would reconsider allowing these means to be used solely for the purpose of protection of the wires.

    Thank you for your posts on this topic. I understand that you disagree with R7 and R11 as they are written and I apologize for the confusion/frustration that this disagreement has caused. We will not be reversing the answers given to this and the previous R7 questions for the 2017-2018 season. However, it has given the GDC a lot to take into consideration for for next year's game manual, and I do sincerely thank you for bringing this concern to our attention.

    With that in mind, the purpose of the Q&A forum is to provide specific rules clarifications and offer official insight when additional interpretation beyond the written manual is necessary. Your original question asked whether or not you can use hot glue to protect the external wires where they enter a 393 motor. This question has been answered multiple times, and we have provided alternative options that are legal within the scope of this year's game manual. If you have further thoughts on this topic that are not specific rules questions, please feel free to contact us by emailing GDC@vex.com .
