I have no idea if this is something that can be implimented,certainly not by me, but is there a way to intentionaly include flaws into a flight model that could cause stall or spins or even structural failure?if that was the case and IF somone had a way to write a "flight model switching program" that could randomly insert the a flight model into an aircrft folder that could make for some interesting test missions.I guess if you had a folder with say 8-10 flightmodels and only a few had the flaws you would get one randomly incerted ino the plane then go test it and see what happens.I'm pretty sure it would be alot of effort but something I was thinking about so I figured I would throw it out there.At the very least it would give someone an excuse to make some of those cool X-planes.
