Actually, I'm not all that old, although I admit to a few grey hairs.
When the high level acro pilots talk about shaving weight in their
planes, I just say I'll go an a diet and lose 30 lbs.

Regarding the blunt LE of the Extra, I thought the intent was to
actually separate the air flow more quickly (or perhaps it is the
squared off TE), in order to get a cleaner snap entry. When it does
break it kind of shudders, especially at high speed, and just a slight
release of the back (forward) pressure will get things going again. In
fact, it's hard to accelerate a spin, especially to the right (at
least in my plane), without it actually stopping the spin and starting
to do a wallow-spiral.


Yeah, I suppose. i expressed it poorly, but what I was driving at was
control of the seperation so you could detach and reattach at will, as
opposed to say, a clark Y type of seperation where you enter a snap and it
take a ridiculous reduction in alpha to stop it. I understand your type of
airplane will stop the instant you ask it to with a minimal change in
alpha.

All I know is that it's a lot of fun to fly, a challenge to land, and
I am very fortunate to be able to own one.

You ae indeed! I thought they were supposed to be fairly easy to land,
though! There's one near me for rent. I really ought to go try it out
someday.
