This really is a wonderfully accurate and well-proportioned model, detailing is on-point, and it's a delight to run. I particularly like the springing in the suspension: very well judged, and this along with the sprung buffers helps it run very well in all kinds of mixed rakes and track radii.
Good value at the current price, too; if you can get prices of future R2R models anywhere close to this you should have a big success on your hands.
