Tamiya cars include the whole RM series and a few other chassis. I dont know about Europe,but here in Japan its hard to find anybody that used one for racing.The few references I have of Tamiya being raced in a national level event are only for the RM mark1 (Lola),after this chassis all of Tamiya`s cars were a year or more behind the technology curve.For example by the time the RM5 was released other companies all ready had ball diffs,height adjustable gear boxes,"T" bars and oil dampers.Tamiya didnt have any of these features.
My buddy runs a RM5 and its a nice car but the fact that you could get a much better handling car for the same price at the time here in Japan could be why you never saw them beeing raced seriously.
