4oz fuel tank, one Cox 0.049 engine swinging a 5x3x3 prop. If she'll lift a full fuel load I'm looking at something like 45-60 minutes of flight time. Won't know till ya try! If she won't carry it, oh well, I'll run a smaller tank, but hopefully she'll carry a full fuel load.
Don't let me forget to document the modifications I have to make to the nose! I might just make an article about it.
