I ask once here and was told yes HO is SCALE. Well I beg to differ. I have been buying lots of flat cars at shows and on ebay for a large logging layout. I worked over two flats today, painting them primmer red, adding chains and stakes. On is an Athearn. The other is Backman. The Athearn is perfect scale behind both my Backman Shays and Cimax. The Backman and also the Life Likes and Tycos are noticably larger in all aspects. To large to look correct. I have mostly these cheap flats I have "bashed" into trypical W Va log flats. To many I think for what I am doing. I may offer them on ebay and replace them with a better quality of car. Do you think it matters? What would you do? Thank you form a new poster.
