Chilli monster, I'd have thought that you meant the other way around? Wingovers can be pretty gentle depending on how aggresively one pitches up etc, but to chandelle a glider from a stable glide would be a rather non-event. You'd just end up at a similar altitude pointing the other way going very slowly!

Aerobatic manouvers
To et a good explanantion of aerobatic manouvers and what they should look like is explained on the British Aerobatic Association website.
See http://www.aerobatics.org.uk/judging/judging-topics.htm for details
Also on the website are contact details of aerobatic pilots around the country who are able to help paople starting aerobatics, see http://www.aerobatics.org.uk/training/buddy_main.htm for details
Good luck and enjoy yourself

IAC
Lister - the IAC, albeit a fine organisation is anything but International! It is the American equivalent of the BAeA - however like boxing organisations in the States it does have competition from the AAA!
The "executive" are elected and they seem to fall out every so often, so dummies are spat and a "better" organisation is formed but they tend to fade into insignificance rapidly. (Sorry, Mr Dorsey!)

Stik,that was the site I looked at before you took me up,it gave me a basic idea of what was going to happen.
I then had to look afterwards to see what had happened!

Aerobatics information
To learn more about aerobatics, I'd strongly recommend "Better Aerobatics" by Alan Cassidy. I've read probably most of the published books about aerobatics (not all of them for sure) and this is definitely the best imo. Lots of practical info about what the manoeuvres are as well as how to fly them. And as a bonus, he's a Brit.

Lazy Eights were taught to me as a more sporting way to get rid of excess altitude in a glider than just popping the spoilers.
There is a wingover at each end.
It helps to choose a road or fence line for alignment as with many aeros.
In a Blanik you accelerate to 70 kt. before pulling up and adding bank using rudder for co-ordination.
It is a positive G maneuver at the apex of the turn. As you gain familiarity with the maneuver maximum bank can reach the 90 degree vicinity and you begin to get into some very atypical aerodynamics.
At the apex the stick will be well back. You then begin to take off bank and reduce pitch to regain airspeed.
You could characterise a wingover as aborting a barrel roll approximately a quarter way through.
Please review first in a/c with qualified instructor at sufficient altitude. Attempted barrel rolls and wingovers by the untutored do sometimes run out of altitude before the maneuver is completed with fatal results to both occupants and airframe

A piece in the current edition of Flyer is worth the read:
Number 3? "The ultimate humble manouvre - the wing over"
albeit used incorrectly by pilots escaping from a
up manoeuvre. Unfortunately it does not seem to be available on the web site.
Manoeuvres that Murder:
"Brian Lecomber lists the three most dangerous aerobatic manoeuvres (you'll never guess what they are) and some tips which will stop them getting you"
"Three words which should be carved in stone: check thy energy"

Wingovers are the normal means of entry to the steep dives used by dive bombers enabling dive entry without resorting to negative g. The steeper the dive the more accurate the delivery.
Technique for example for the Mustang was to approach a target a little to one side and 7,000 feet above so that the target appeared to disappear for a few seconds as it went under an inboard section of the wing. Then one would execute the start of a barrel roll, pulling the nose hard up, over and well down through the horizon whilst inverted meanwhile rolling out to line up on the target in a steady 60 degree dive. This 60 degree dive angle appears to the pilot to be almost vertical.
This manoeuvre would result in a reversal of direction and a stabilised dive to the release point quickly followed by a high g pull out.
Perhaps there is yet an old Stukka pilot out there who can describe the dive entry for one of those.

Dr. Günther Eichhorn's website has this info - which is the way I do them myself. From memory, the local military do it per Dave Robson's book - pull up until 15 - 20 deg above the horizon, roll to 90 deg bank angle, stop the roll, maintain back pressure at about 2 g - get the book to see the rest.
I teach wingovers slightly differently. The aim is to turn through 180 degrees whilst (maybe) gaining a little energy.
Accelerate to at least 2.5Vs, look at horizon at wingtip and hold it there while pitching to 60deg, unload to zero'ish g, pause, co-ordinated smooth roll (look down side of nose) with a little back pressure such that after 90 degrees the fuselage is horizontal and pointing where the wingtip was and the wings have just reached vertical, look back for the line and smoothly coordinate pitch and roll so that you just pass through fuselage level just as the wings reach level just as you reach your entry height and speed and perfectly on the line - that's the theory anyway.
Chandelles are a speed_for_height turn-around, flown at about the same min speed: roll to 30 degrees AOB, smoothly pitch to 30 degrees, bank reaches a max of about 60 deg at 90 degree point, from there on smoothly coordinate pitch and roll to struggle away from the stall without sagging. Easiest done when at 90 degrees to the reference.
Someone commented that wingovers aren't in the catalogue, neither are simple aileron rolls but they're also great for a first manouvre to build confidence.
HTH but please don't self teach aeros.
