I was very carefully avoiding that
I don't understand the confusion of terms (neither do I think it matters, except if it's about bragging rights):
A flip is a flip. A piro is a piro. A flip combined with
one piro is a xxx? A flip combined with
three piros is a piroflip?
For me it's a piroflip, as soon as you combine the moves.
Now my opinions don't really matter, but what if I turn it around: How many
flips can you do per
piro? (hint: use rudder trim in the sim to find out...)
No, the main dificulty is IMO to "fly" through the move - stay connected with the heli at any time and do the right correction.
Adding more piros (or more flips) is then rather straightforward.
