I'm pretty certain it's the perspective, and not then being larger. I'm not saying they're not larger...honestly, I don't know if they're larger, or smaller...but, if you zoom in on the 'comparison' photo, you should immediately notice something "peculiar" about the steering linkage - in the photo, the steering linkage on the SCX10.3 appears to be twice as thick (in diameter) as the steering linkage of the SCX10.2.
I think it's highly unlikely that the linkage is twice the diameter, which can only mean that the perspective is NOT matching. In other words, either the SCX10.3 half of the photo IS closer to the camera, or the SCX10.3 half was slightly "zoomed in". With way, it is not a true side-by-side comparison. Sorry, Rich, but, unless the steering linkage is truly twice the diameter (and, if I'm wrong, I apologize), I've got to call out the "marketing hype" on that photo.
