No, not contra-rotating.
I would have thought people on this forum would know what supra-convergent means!
To stop further irrelevant replies:
Supra-convergent - upper prop tips rotate inwards towards aircraft centreline
Supra-divergent - upper prop tips rotate outwards away from centreline
Why are the inner props supra-divergent? One would anticipate that normally all props would be supra-convergent to reduce P-factor.
