Thanks for your post, BritDriver. Good to read your description of the loop. When I flew our Mk IV it was mostly in formations, not solo display, so my aerobatic flying in it was limited.

There have been 3 Hurris flying here in Canada in recent decades. I've flown two of them, and Joe C, who took over from me after these flights, has flown all three. They were all light in the tail when airborne, not heavy, but of course none of them were Sea Hurricanes. They are difficult to 3-point with power-off and full-flap. You run out of elevator authority. Which is not in the books...
Ours tracks straight on the ground. No habit of dirty-darts so far, and Gatineau is a very crosswindy place. But our IV was a bit quirky at times. (Past tense now, of course.) Oddly, it was worst when taking off with a couple of knots of tailwind -- it tended to head for the grass in that situation.
