I've read in reviews that the road wheels of this kit are slightly under-sized, and comparative photos of the real item bear this out. It seems the rubber tire portion might be a little too narrow. I was wondering if glueing thin styrene (1/4 mm) strip around the tires would solve the problem. At any rate, it would reduce the space between the wheels.
Another comment: has anyone built this kit, and how, if at all, have you dealt with trying to fit a crew in action in the compartment?
