i didnt take it as you were doing anything but agreeing with me george. from other postings i have gathered from some others that true scale is the only thing that counts. and thats fine, to each his own. i do strive for this as much as is possible. but to me and again i say "to me" what is important is if it looks right. when i put the vector in the dr.1 cowl even if i cut off a few rockers to my eye i can tell that the exposed rockers wouldnt clear the cowl. i only mean to say so what if an engine is 28mm across or 29mm across if i can put it in my kit without wasting hours trying to force a round peg in a square hole and if it looks the part thats my goal. it should be enjoyable and fighting a fit problem is annoying not fun. its like the 1/48 mercedes engine issue. the roden engine(closer to true scale) looks better than eduards. am companies(vector,pavla,etc.) use rodens block to make their resin engine masters. they dont fit in eduard,special hobby,mirage,etc.etc.kits. i dont see why someone cant make an engine that fits 90% of 1/48 kits without having to compromise this that or chopping up the kit or engine to make it fit. i would rather compromise scale and have an engine thats 1/49 or 1/50 but looks great and i dont have to fight to get it in. you have to compromise its just what you choose to compromise.
