One of the fastest rolling aircraft around is the A-4 Skyhawk at up to 720 degrees/sec. Enough roll acceleration to bang your head off the canopy if you aren't the one flying (2 seat versions). Enough roll rate to over-pressurize the wing fuel tank from centrifugal force effects and damage the wing (I've investigated some of the resulting incidents). Max roll rate only allowed for one 360 degree roll before stopping it due to roll-pitch coupling.
