The wheels have little bearings but they dont all run straight and I havent the interest to go faffing about with them. If I ever RC it I will see how bad they look (its a 1 mm cant on a full rotation for two of them).
I like 1:10 scale as its big but not awkward but even though the scale is nice, there are no parts availabel except from German artisans which normal folk cannot really afford.
