I can not obsess over this more. Adding a gyro into the brain is an extremely cheap upgrade, and A GYRO BUILT INTO THE BRAIN WOULD HELP SOOOO MUCH!!! IQ just got one, so…V6? Hopefully? Please?
a gyro in the brain would just be one more thing that could break and you couldn’t replace. not my style. plus there is a real advantage to being able to place your gyro anywhere
I think that an integrated gyro in the brain is a worthwhile value-add to the v5 system because it encourages their use in classrooms and by new teams who are reluctant to find a place to place and wire an independent gyro but would be happy to use an integrated one. As far as reliability, it’s fine if it breaks and cannot be replaced because it likely wouldn’t impede the core functionality (motors, sensors, programs). While there are advantages to placing gyros anywhere I’d imagine that you’d still be able to do that and reference the external gyro.
I think that it may be like the integration of encoders in the v5 motors in that teams may not have bothered to add and use encoders but after they were integrated even new teams are able to utilize that function.
I don’t see them adding an integrated gyro now that they released an external one at least for a while. the v5 system is relatively new still.
My mentor came up with this: Vex branded 3d printer filament. It could be black with red flecks (for VEX V5) or maybe VEX 
green. It would be proprietary PLA which is easily visually identifiable and distinguishable from other options.
The main reason why VEX does not allow 3d printed parts is potential lost sales in bearings, gears, brackets, and other parts. If they sold proprietary PLA they could adjust the cost so that it is similar to or more expensive than buying their parts.
They could ensure teams purchase their filament due to safety concerns, and perhaps have restrictions on the quantity allowed for use (1/4 kilo) to allay concerns about economic equity between teams.
This was discussed some here:
Well, not likely… Here’s a couple points: (1) VEX doesn’t make the rules, the REC Foundation makes the rules. VEX is a for-profit company, a division of IFI (Innovation First) that makes most of their money selling parts for educational use, while REC Foundation, although closely related to vex, is a non-profit foundation that make the rules for the game and organizes competition, etc. (2) As vocal and outspoken as competition robotics students are, the small amount of profit from selling bearings/gears etc to competition teams is nothing compared to education sales to schools.
For now, we’ll have to stick to “the main reason” beings something like the “level playing field” arguments or whatever argument anybody (besides me, I don’t really care either way) wants to pose.
Magic!
I now really wish 3 wide and 5 wide c-channel had center holes like 2 wide does.
I guess they excluded them for structural strength reasons
oh man the amount of unorthodox holes ive had to drill into my three wides…
