I use blender to model usually its weapons or creatures,mostly just fiddlin around lol I had over a hundred hours on an axe, a friggin double bladed axe...... I can only inagine what a n intire plane must be, I actully thought about doing a P40, but never started it. once I started the painting process...thats to get the creature to move, wow worse then the modeling itself lol, its a very serious PITA I give major kudos to the HTC staff.
