Thank you Joe for your comments.

I agree with you about the 1/4" angle. I see teams driving down to thinner and thinner metals so to see something that thick makes me wonder.

Last year we accidentally ran our .090" 5052-H32 sheet metal frame into a cement column at full speed without bumpers. We ended up with a little ding on the flange, but the structural integrity remained. Made me think we could have gone to .080 or maybe even less.

I always like to know the tradeoffs on various drivetrain designs so I can help our students understand the tradeoffs and make decisions according to what we need.

I am also constantly looking for designs that use less precision machining because I see a lot of teams without that capability. That is one thing interesting about this design.
