If you're looking at anything near the edge of the performance envelope for FRC applications, I might be a little wary. Those gears can be swapped for their steel counterparts, but I'm not really savvy to that process. I'm developing a theory about these failures and I think it has to do with the elastic range of the gear material and shock loading in the drive train, because while similar in strength 7075 aluminum isn't as tough as 4140 steel.
If you're looking at an off season project, have you considered designing your own gearbox? It's not as hard as it sounds and people have found ways to make things exceptionally compact. I personally don't feel like any of the options on the market are particularly small. If you have any questions along those lines, I'm happy to help.

Designing a gearbox offseason is something I'm interested in but I have no experience designing a shifting gearbox. I'm not 100% sure on how they work but I have a pretty good idea. Can someone explain the method of how one works and maybe help provide some tips for designing one? After really bad luck with the vexpro ss gearboxes, I think our team wants to design our own.
