I wouldn't call it "unfair"...and, I don't believe I ever said anything about "expecting" it to fit the Capra. All I said was that some have tried them in their Capra, discovered there was a "problem", and that they reported the problem in the Capra threads.
I read what they described, and compared it to what was described by those who installed the gears in the very vehicles the gears were designed for (as those people described almost identical "problems"), and realized that both groups were, essentially, describing the same problem. As such, it didn't appear to be a specific vehicle problem (ie. not specific to the Capra). When SSD mentioned they had only tested the gears in the own housings, and would test then in the vehicle's manufacturer-produced housing, that's when I asked if they could also test in the Capra's housing.
If the gears are designed for the SCX10 II, and if the SCX10 II & Capra use the same diameter gears (as well as the same size bearings)...which, I admit, I don't know if they do...then it would seem the OD gears should possibly be able to be used in both vehicles, right? Likewise, if those interested in their Capra, and those installing in their SCX10 II (with Axial housing) are describing the same problem, then it would seem that the problem the Capra builders are having might not be related to the Capra.
If it turns out that the OD gears can only be used with the SSD housing (which they haven't indicated), then so be it...but, if the gears are supposed to work in the SCX10 II's Axial-made housing, and they aren't, then the problem is, obviously, something else.
