the guy publicly offered it to you but you thank him in private somehow like everything else u write I seriously doubt it
you want proof of it? ask him to quote it for you. i bet he'd be glad to show you that i thanked him in a PM.
im done with you, all you try to do is start a pissing contest and then take threads off-course.
The engine will let you stay near your stall speed for a period of time by providing energy, but it will not provide lift so it will not change your stall speed.
dang, forgot about the lift thing. totally left thru the back-door of my mind

but the engine can save you if your in a pinch, just need to know how to effectivly use it. the engine is just as vital as the wings providing the lift, the engine can pull you up even when the wings arent producing enough lift to stay up.
