So the other day I was in a Spit XIV with 4 guys on my six. I was hauling butt, doing half mach or so at around 12K. Anyways, I discover one of the pursuers is just 400 feet off my tail, and I quickly pull up, then roll hard right with full right rudder.
My Spit XIV immediately goes into some weird sort of pseudo-stall...I'm maintaining alt, but my speed is bleeding, my stall alarm is going off, and my plane is rolling at a ridiculous rate...something between 2-3 rolls per second. So much in fact that for a few seconds I thought I had lost a wing. It ended up being very easy to recover from (and it lost the bogey).
I've tried to replicate this fast-roll manuever since and failed. Is it a glitch or something funky with that overpowered super-Spit?
what probably happened was a departure stall. what that is, is when your wing exceeds the critical angle of attack to the oncomming wind. now..understand, if you're pitched 30 degrees nose up, then the oncomming wind to the wing is going downard. on GA aircraft, i think it's about 17 degrees. assume the same for your spit. as you're flying, you're actually somewhere in the area of 8-11 degrees to the oncomming wind. now your sudden pull on the elevator, and kicking full rudder, caused the nose to jerk upward suddenly, momentarily exceeding the wing's critical angle....at this point, it can no longer create lift untill it's allowed to come back into its window. combined with the rudder, you did what sounds a lot like a snap roll. you lost the bogy because you suddenly bled speed, much faster than he could correct to follow ya. that's never worked for me in here, but i'm still learning
now bear in mind, i'm not too good in the arenas yet, but from what i read, and, using what i know from flying cessnas(and an hour in a super decathalon too), thats what it sounded like to me.
now,
