Mike Goulian is testing out a new oil tank set up, which has saved the American pilot about 3kg
He clocks in at 1:07.663, behind Kopfstein
The Spanish pilot Velarde is out into the track next
Technical issues on the ground for Velarde means he'll have to wait until the end of the session to fly his Free Practice 3 run
So next up it's Le Vot of France... he made a surprise podium visit at the start of the season but we've yet to see him maintain a consistently strong performance. But he is working on it...
1:10.817 for Le Vot... way off the pace here unfortunately
Canada's Pete McLeod flies next – he's sitting in 9th overall – which will be immensely frustrating for the young pilot
We always speak too soon... that's an epic run for McLeod! He stops the clock in 1:05.989 to lead as we get to the halfway point of the session! Go Pete!
Another pilot looking to climb the standings as we move into the second half of the season is Martin Sonka of the Czech Republic. He's a step above McLeod in the overall standings with just 1.5 points between them
It's not looking great out there for Sonka as he picks up 2s for incorrect level – it's a 1:08.544
Now we're into the top half of the table – this is where it should get exciting! But can anyone top Dolderer's time from yesterday of 1:05.224?
It's Australia's Matt Hall up now!
Hall posts a strong 1:06.794 to sit behind McLeod
Next up we've got the man of the moment for the UK fans, Nigel Lamb!
It's a clean run, but just not fast enough to make it to the top – 1:07.486
Ivanoff flies next – he had a podium here in 2014 with a 3rd place – could he pull it out of the bag again for the British crowd?
He's in 5th overall with 22 points to his name... he could still be within a shot of the title but it's a long one...
Great flying from Ivanoff! That run is enough to put him hot on the heels of McLeod with a 1:06.345!
Yoshihide Muroya goes next into the track and he's another podium hopeful who could steal Dolderer's crown... he's 4th overall on 22.5 points and very capable of a win
Muroya picks up double penalties in his first run but keeps it clean for his second go, to post a 1:07.237 putting him in 3rd place, with 4 to fly...
Chambliss goes next and the American has been in the Final 4 in the last two rounds... so don't underestimate this competitor, he's here to win!
It's a 1:08.541 time that will count from his second run... the first run would have been pretty strong, except that he picked up a pylon hit and 3s in penalties... it would have been a 1:06 otherwise :(
Arch and Dolderer left to go, with Velarde running at the end of the session due to an earlier technical issue
Arch is sitting in 2nd overall and says he likes to be 'the hunter'
There's 15.25 points between him and Dolderer – so even with a win and the German passing on points, he won't be able to push past at Ascot... but we might see the gap shorten
NO! That's a course deviation for the Austrian in his first run = DNF
But a second run proves more promising... maybe he's experimenting here? It's clean but only a 1:07.991 which is 2s off McLeod's pace
Penultimate pilot for this last Free Practice session is Dolderer – all eyes are on the German, who could be heading for a first World Championship title in 2016
