Not entirely related to our recent conversation, but in case you want to take in consideration a proper alternative to the stock US Heavy Bomber, I cant point you to several Liberator models, including one model ripped from "Enemy Front" and two models coming from a popular SHIV megamod.
All of the above represent different variants of the aircraft, so if you don't want to trash the work you have already done on the stock model, you can use the alternative models as templates for checking proportions and for creating different variants of the bomber
