I was thinking of the same thing. LOOPS AND ROLLS? Not to mention one even has to be proficient at FA3 or be TOC modeler just to solo a trainer? Sounds more like a hazing ritual to me.

The focus of the solo requirement should be on safety and minimal proficiency.

As long as one can demonstrate reasonable control of the model during climb, descend plus able to enter pattern and do 3 completely unassisted landings and takeoffs. Most importantly, one should exercise reasonable judgement and know when to dump a plane rather that trying to save it should it become unsafe to do so. Solo means one can fly the model unassisted, and it is just the beginning point to learn something more challenging, nothing more.
