Nemesis 4x5=20
Air 4x2=8
Corkscrew 2x2=4
TraumaTizer 1x5=5
Some death trap Pinfarri 2(3?)x1=2/3
That makes 39/40, not a lot at all, but this does not include flats, which would bring it up a bit.
But how many people here can say they have done stunts in a light aircraft? That brings it up even more, about 50-100%.
