Rolling a 172 - or not

Lets kill this thread right now.

1. A 'barrel roll' is a roll where (if done properly) you as a
passenger, with your eyes closed, can not tell you did a roll. The
ball stays centered and if one 'G' is maintained, it feels like
straight and level flight. Starting nose position and of course air
speed varies between underpoweed GA aircraft and super sonic Fghters.

2. A 'slow roll' (point roll) is done with the nose pointing at a
single point (normally picked out o horizon) all the way around. In
Fighters, can be done from straigaht and level flight. Most GA
aircraft require a little airspeed above cruise. To do you raise the
nose above the point on the horizion and start a roll with aileron. As
you continue the roll you feed in top rudder to hold nose up and
adjust the elevator to keep nose on the point. As roll continues you
feed in down elevator (here's your negative G's) to hold the nose up
and on the point while relaxing the top rudder input. As roll
continues you again feed in top rudder (opposite rudder) to hold nose
up on point and take off down elevator holding nose on point. After
passing the 270 degree position, you start removing top rudder and
adjust the elevator to keep nose on point. As you come back out
straight and level all controls are again in neutral. Negatiave "G's"
are of course pulled when on your back. Roll can be relatitivly slow
or rapid as long as nose can be held on a point going around.

3. An aileron roll is just laying the aileron over (normally full
aileron) and letting bird roll. Depending on type of aircraft (fighter
or GA) the nose makes a circle around a point. Fighters can do at
cruise with little or no nose above the horizon. GA requires a start
with the nose above the horizon due to slower rate of roll and bird
ending up nose low because no other control input to hold nose up
while inverted is used

There are also a few fine points the experts use that I have not
covered but above are the basics.

Been there done that for longer (65 years) than BOb has been flying.

If I'm crusing along at 100 KIAS in a 172 in clear air and I roll left
while maintaining neutral rudder, what will happen if I don't
neutralize the ailerons?

I'm picturing the plane rolling on to its back while losing altitude
and either completing the roll (doubtful) or stalling into a dive and
recovering in the other direction , right side up. (BTW, that's a
split-S, isn't it?)
