We also learned this lesson the hard way on the WCP SS gearbox. Fortunately it first happened during our 6-hour unbag window prior to our first competition, so it didn't cost us any matches. It did cost us 2x 45 minute teardown sessions (1 during unbag, and 1 at the event) to upgrade both competition gearboxes - We were also fortunate to already have the 14T steel gears on-hand, spared for another mechanism.

We also helped get 4469 back up and running with steel gears at PNW DCMP after they stripped the same 14T aluminum gear in the Vex 2-stage SS gearbox.

R.C. - It would be great if these two gearboxes were configurable with steel 14T gears, or even came with them by default for the relevant gear ratios. Currently only aluminum is available when building a gearbox for purchase through Vex or WCP - steel replacements have to be purchased separately.
