very good points dave.but to myself personally i dont get to hung up on exact scale accuracy of the eduard engine being a smidge small, i would rather have a well detailed engine that will fit in my tons of kits that i have. i dont like to think about doing surgery to every single albatroa,pfalz,fokker etc that i build. besides i doubt any of the 1/48 kits are perfect scale anyways,none fit drawings exactly,its a few mm here too short or too long plus the scale wall thickness is off on every kit ever made. to me i would absolutely love to have accurately detailed engines to fit my kits. besides this is bo doing us a favor by scaling his cylinders so that we can pay shapeways to print some for us to use on our models. i thought berman is doing a full series that will be full size for the roden d.vii,which i would use for these kits if not one of my vector or pavla engines. i just love the eduard, special hobby, etc kits and dont want to have to scrape and slice and trim in order to force the engine in and then it doesnt sit right anyway like the prop spindle doesnt line upand you cant use the kit exhaust, etc.so i must agree to disagree and hope that we both get what maks us happy in the long run.
also the eduard white metal engine is exactly the same parts as the plastic ones.i took them out to look.as for csm they did have early aeroclub stuff in some kits but i am sure that they had an eduard resin copy in at least the hb.w12 and i thought the aeg c.iv but then i did buy them second hand maybe the parts were switched around.
