Well, as a little known "factoid", the fullscale UAV Predator crashes about 20% of the time at $1.5M a smash [:@][:@] all those "cool commercials" featuring them are straight PR. They NEVER show the landings......

your tax dollars at work [:-]

Personally, I'd be a little nervous about that inverted stabilizer. I know a couple of people with "pusher" aircraft and they have some problems with the props nicking the ground on an uneven field or a "butt heavy" landing. I'd think that the UAV Predator would suffer from alot of those same problems ( a little "flare" on the landing and SCRAPE! you've nicked your tail stabilizers....)
