Thanks my friends @johnb and @eb801!
Yep, the kit needs some extra work, but, hopefully it did progress steadily.
Yep, the wheels lack the "bulge" effect, they are just flattened. Since the wheels sit at a distinctively positive camber angle, hopefully the effect might not be too obvious...
The white metal gear is not bad (thank goodness it is not provided in prone-to-buckling resin), but the metal itself is VERY soft, among the softest I have experienced. I would not mind for it being tad harder...
