If a normal ... aircraft allows stalls, then isn't that inferring that its not an aerobatic manoevre? At least in the mind of the designer.
Nope, in recognition of the USA airworthiness regs (which most of the rest of the world also recognises and copies). So, good to be consistent with the USA rules for a number of reasons, one being that they are generally quite sensible.
I seem to recall someone doing negative g turns in the circuit??????
But not aerobatics per the old rules in my opinion!
