""It took me a long time to realise that a model in a Right Spiral Climb has to Roll to the Left while trying to loop.""
You're not alone there, Ricardo

We don't exactly help ourselves to get that - we use the same words ('left' and 'right') for both turn and roll.
If we think of roll in clockwise terms instead, and just use left and right to describe turn, we can mentally separate
turn and roll more easily.
