After reading through to rules for the umpteenth time
, I could NOT find anything talking about the relationship of mentor vs student design or manufacture. So I will give my opinion.
This program is about building relationship WITH sponsors, mentors, and students. It is to help students work WITH the professionals not FOR the professional. Professionals can and are both students and mentors. Some students are absolutely capable of teaching adults. I personally have seen students who design and manufacture circles around me and tip my cap to them.
So each team should evaluate their own capabilities and leave others capabilities to them.
