This has prolly already been discussed somewhere but the few searches I did yielded nothing.
I have been flying the SpitI a lot lately and have found that you can put the craft into an unrecoverable floating upside down "flat spin" although it doesn't "spin" so much as wobble. The nose will never drop and nothing, flaps, gear,aileron, rudder, cussing ,swearing, throwing headsets, pleading or tapping shoes together while chanting "theres no place like home" will help.
I know, before you jump me , its poor piloting skills that get me into that predicament. Just wondering, did the real ones have that problem. I cant seem to duplicate it in any of the other Spits.
