Overall leader Nigel Lamp of the UK finished only in fourth place, while Arch flew an immaculate round on a sunny afternoon in the autumnal Austrian alps.
Germany’s Matthias Dolderer came second in qualifying while Martin Sonka of the Czech Republic was in third place.
“It’s a super feeling to get everything out of the airplane and everything out of my abilities,” said Arch, who won the race in Rovinj, Croatia after winning qualifying there. “I’m really pleased that I’m performing the way I’m capable of. A big thanks to my team for the great preparation. It’s super to have so many people out here supporting us. I can feel all that energy from the crowd when I’m out there on the track.”
“I didn’t think I flew badly. The other guys just flew better than me,” said Lamb, who has one race victory this season and four straight second place finishes. “I did actually make some modifications in my lines a bit before Qualifying and we thought they would make us faster. But I don’t know. We’ll take another look at the lines. Maybe we’ll find that those were modifications were not a good idea so I’ll go back to what I did before. Hannes’s time is just a blinding time. I mean it’s unbelievable. Tomorrow is another day.”
