Rolling a 172 - or not

"Hamish Reid"

You don't have positive G all the way around in an aileron roll.

In a properly done aileron roll you certainly do...

To maintain positive G, you need a barrel roll.

Or an aileron roll. Were you thinking of a slow roll?

I'm confused. Please describe a properly done aileron roll.

I have some glider acro training and lot's of RC model acro. I think of
axial rolls and barrel rolls. Both benefit from aileron, elevator and
rudder input. I've thought that aileron roles are synonymous with axial and
slow rolls synonymous with barrel rolls. But there is a lot of RC legacy
stuff in my understanding.
