i suggested an eduard sized engine as there is the vector and pavla to replace roden sized engines. the vast majority or 1/48 kits require either an eduard sized engine or major surgery an/or trimming of pieces/parts off the vector engine to make it fit. the roden block is nicer in and of itself which is why vector et al used this as there basis. if it was just a simple thing like thinning a cowl that would be one thing but the length/width and height just dont work if you want to put a roden type engine in any kit other than rodens. which is basically the fokker d.vii series. eduard makes albatros d.iii, albatros d.v,that pfalz d.iii.d.iia,roland c.ii,fokker d.vii series,the old albatros c.iii,special hobby has the pfalz d.xii early and late the new albatros c.iii etc,hi tech has the roland d.ii which had a smaller engine,the old dml kits have a smaller eduard size engine, the karaya cl.iv would need the smaller eduard engine, and does any/all copper state kits which used an eduard copy. this list goes on and on.it personally think it would be amazing to have an engine that would be the right size to drop into 95% of all 1/48 kits requireing a mercedes d.iii series engine rather than having yet another one to fit into the roden fokker d.vii kits. this is just my opinion but it is also been something that many 1/48 modellers have lamented over for years. yes the eduard engine is slightly under scale but wouldnt it be nice if you didnt have to spend hours chopping up vitually every 1/48 kit to get the larger nice vector engine to fit in it? to me an eduard sized accurate engine series would be a godsend because you can use it without modification in every kit including the roden d.vii.
perhaps a cylinder array 1 for 160hp and one for 180/200hp with accurate rocker covers/spring detail which could be stuck on top the eduard sized kit blocks?
