Are there any scale models of our military UAV's? I'm not looking to build a drone for "dronish" purposes, but a military UAV to take to warbird events. I mainly fly IMAC and getting back into helicopters, but I've always wanted to build a 1/3 scale Preditor or a 1/5 scale Global Hawk (I'd like to keep it in the sub 100" wing span area, ~50-80 cc gasser power)

Any ideas?
