Lanny, I could see where it could be done but I do not know where to find a 1/25 scale engine. If you used an engine from a 2007 1/24 scale Revell kit it would not look right. It would be way too big. AMT could have sold a lot more of these kits if they had just made them 1/24 scale. It would not have been that much more plastic in each kit to have done it. Pretty bad decision on their part.
