Round 2 and the same name at the top, and same top 4 just in a different order as Tom Cockerill took provisional TQ in the B heat, underlining  his own pace as well as the Yokomo’s.  Out front however once again Bruno Coelho shot out of the blocks and if it hadn’t have been for a cartwheeling crash moment he would have swept past the loop for the day’s first 18-lap run.

Whilst the times are closer on the results, the true story is that Orlowski kept a cleaner race with only one off lap whilst Coelho had significantly better pace over the 5 mins but one lap of over 20 secs and a last lap of 18.1 which ultimately cost him the additional victory TQ lap.


Moving into 3rd David Ronnefalk, running a modified HB D413 buggy, whilst Martin Bayer had a considerably better round, but looks like he has the pace for the top 3. Once again Naoto Matsukura was running strongly near the top for a top 3 finish but a roll over after the table top cost him his chance, whilst Yusuke Sugiura has endured a rubbish first half of quali with a 10th and an 11th place in Q2.

Bruno Coelho gave the new XRAY XB4’16 a perfect debut as he swept to TQ in round 1 of qualifying, in only his second big international 1/10th race he is upsetting the delicate balance of 4WD despite having spent the last two weeks practicing intensively at XRAY’s impressive indoor facility Hudy Arena with the help from team mate Bayer as well who himself was setting the pace early on in the final qualifier but a series of terrible mistakes cost him.

Bruno looked in final practice to have a slight edge on raw laptime over practice TQ Yusuke Sugiura, however errors cost the Kyosho driver as he would struggle to only 10th. Another driver that would have made it inside the top 5 was 14 year old Kaito Kodera, on for a 17/5:05, a massive error on the last lap on the straight saw him lose 6-7 seconds, disastrous finish after such a strong run. Similarly Naoto Matsukura, initially leading the final heat then running 2nd behind Coelho hit problems on lap 13 and retired.


No such problems for Tom Cockerill taking a surprise 2nd for the round, a surprised yet delighted reaction as he was confirmed as ‘best of the rest’ having marshalled the top heat. It would appear Yokomo have found some pace after yesterday’s morning struggle, 4 cars in the tight top 10, joined by two HB drivers of Ronnefalk and Tessmann. Another consistent showing from Poland’s Michal Orlowski, less than 2/100ths behind Cockerill, even 2nd-5th separated by less than 4/10ths proving how every half a bobble or landing matters at this level.

The question remains, Coelho’s 5 sec gap was mightily impressive.

Results: Final Practice

Friday morning’s final round of ‘free practice’ in the new revised heats saw Yusuke Sugiura once again set the pace over the 5 mins, showing he’s definitely a good bet for qualifying however all eyes should also be on Bruno Coelho, setting 3 consecutive laps of 51.705, comparing with Sugiura’s 52.319 – it would appear that Coelho just as yesterday has potentially more raw pace but is more inconsistent, reinforced by a very slow last lap which dropped him from 2nd to 6th.

The surprise names making it inside the top 10 were Hayato Matsuzaki, 2007 2WD World Champion in 4th and Kai Kikuchi in 8th whilst 14 year old Kaito Kodera looks ready for quali in 9th.
