does the canopy have to be air-locked?

Ewe might want to advoid that kid, the only full barrel roll I've ever seen
came out of a radical opening, looking up and seeing the runway over yer canopy
is skury. I don't think air-lock had been invented yet it was back when zp was
only used on top or bottom skin, not both sides. A brand new outta the bag F111
falcon was the canopy I saw barrel roll. Why don't you just try to jump without
stacking the odds against yourself? :-o) wiley

hehe.. but you must do it downwind!!!!!

Bullshit, but then you do slip in a little qualifier, "most canopies".
Here is a cut and paste of a post from John Leblanc posted on the subject
from awhile back. And BTW, my vx 89 does nice barrel rolls. I dive on my
front risers or do a front riser turn to dive and build up speed. Ease up
on the riser/risers gradually to let the canopy plane out, mine will even
start climbing a little on its own if the dive was fairly aggressive. As it
planes out or starts to climb, I go to about 1/4 or 1/3 brakes for a steep
climb. Before the speed bleeds off, simultaneously ease up on one toggle
and add more of the other. Do this smoothly but firmly. After you go over
the top, ease back to neutral on both toggles and counter steer if you have
to, to stop and stay on heading.

This barrelroll talk is getting pretty wild, and I think someone could get
hurt.
First, this stuff started years ago when people saw the barrel roll I made
(in front of cameraman Gus Wing) that was used in the Tom Sanders movie
"Over the Edge." It is in the PD commercial at the end, if you're still
watching by then. Its not in the Blockbuster movie rental version.
Second, it is not a tandem photographers trick, and it is not bull****. As
to how far above the canopy you can get, Tom freezes a frame at the top
with the horizon in view, so it is pretty clear how far over the top it is.
(I did buy beer, but I doubt I was the first.) At the same time, in the
upside down part of the maneuver, you are starting to go "downhill," so the
canopy is slightly behind you. It needs to be there to keep the canopy
loaded up, for self-preservation. This doesn't mean it is not a barrelroll.
People doing barrelrolls in aircraft not certified for aerobatics do the
same thing: They keep the wing positively loaded all the way around, and
they're going downhill at the top. A roll made in a straight line is called
an aileron roll, and parachutes won't do one. If the nose gets too far out
in front of you, the canopy will get a negative angle of attack, and you
will fall into it, whether the canopy is airlocked or not.
Third, and most important, it is not a radical maneuver! Don't start
yanking down on the toggles and risers aggressively, or you'll be in real
serious trouble. It is an energy conservation maneuver, where speed is
transferred into lift for a steep climb, then a smooth, gentle "turn" is
made in brakes, which creates the barrell roll. One toggle is only three or
four inches lower than the other. It is very similar to a big wide spiral
dive at the ground, but it is made horizontal to the ground instead.
If this is not clear, don't mess with it. I've been getting questions on
this for years, and I've always kept quiet on the newsgroup about it until
now, but the guesses and poor advice I'm seeing is really troublesome. I've
talked to many people about this, and many of them have been in deep...
trouble. Certainly, any manuever involving stalling one side of the canopy,
either on toggle or rear risers, is a real mess. Also avoid any radical
turn reversals from right to left or visa versa, unless you like spinning
line twisted mals. You need a really efficient canopy, but not one that is
too small, as this kills lots of efficiency. The elliptical planform helps
keep the turn rate up at the comparatively slow speed over the top. The PD
Stiletto, and Vengeance do nice barrelrolls. I haven't flown a Diablo yet,
so I couldn't comment on it.
So if you want to risk it, start gradually. Always stay smooth and slow,
not radical. Start with a clear and pull alone at 13500, and stop
experimenting at 5 or 6 thousand feet. Work gradually up to it over many,
many jumps. It is an energy conservation maneuver, not an aggressive
testosterone thing. You might want to insure your rig is good for cutting
away from line twists with no problem. Large three rings and hard channels
in the risers for the end of the cutaway cables are prudent, as are hard
cutaway cable housings. Fly smart, don't kill yourself. As Jacques said,
"Please don't try this based on my thoughts."

He oscillated from one side to the other, finally getting enough momentum to go
into a complete barrel roll and he said it scared him shitless when he went
over the top and he was looking down on his canopy as his lines went slack!
Fortunately, he had enough momentum to fall in front of the canopy thus
re-inflate it. Otherwise, he would have "giftwrapped" himself into the ground.

speaking of that particular Monarch.. a 215 I believe...... Larry---->Roys
brother in law bought it just a few months before my stroke. Do you remember
them? Are they still jumping at Waller Mike? :-* snuffy

You might want to ask Brian (Germain) about that. He's the one who taught
me how to do them.

BTW, weren't you at the Canadian record attempt at Burnaby last year?

at that altitude,if he haddn't been doing a barrel roll, the 360 would have
pointed him at the ground and killed him
also, notice that the nose is pointing at the camera the entire time.......
