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.
