That is my problem not that I can't model in fact quiet the opposite I can. But I first want a basic model that fits the description what I am aiming for is the getting to FL410 in 25mins at Mach .92. I will then after getting relatively close will start modeling more so far it is only a plane maker object and I may have done a by much just for plane maker but if you bare with me I promise that i will work double speed over these next Christmas weeks!
