I'd like to know where you're going to find model turbines that produce 80# of thrust. 20 - 3- pounds is average for what's on the market and 45# is the biggest I'm familiar with.

And since the average F-22 would weigh in at 20 - 30lbs, having 160lbs of thrust would be VERY fast - at least for a few seconds, then the wings and tail surfaces would be blown off just seconds before a terrific crash.
