Matsukura top seed for qualifying

sun_matsukura

Picking up where he left off in free practice yesterday, Naoto Matsukura has topped controlled practice to put himself top seed for qualifying at the 1:12 World Championships in China.  Chasing a fourth World title in the class, the Roche driver was considerably faster than his rivals over 3-consecutive laps, his time a 36.462 compared to the next best of 37.000 set by a much improved Keven Hebert. With Toto Ebukuro completing the Top 3 it wasn’t the best of mornings for reigning World Champion Marc Rheinard.  Having had his time, a P5, for the first of the two controlled practices disallowed for his tyres not being marked, CP2 didn’t start out well as he had to pull off to have his rear tyres tightened.  Rejoining he would eventually get three laps that would leave him 7th quickest one spot ahead of reigning European Champion Alexander Hagberg.

Setting his impressive 3-laps in CP1,  Matsukura would make a set-up change for the second but it left him struggling for traction leading to a number of big crashes one which required his car to need running repairs. Declaring the first practice as ‘very good’, him able to post a 12.051 fastest lap of the two rounds, the 22-year-old said he ‘had too much steering and lacked traction’ for CP2 and so he will go back to his early set-up for the first of the 6 scheduled qualifiers – the best three determining the line up for the finals.  With the 2008/10/12 Champion clearly the fastest driver on outright pace, the Japanese driver himself admitted 8-minutes would be a different challenge declaring it will be ‘super difficult’ to go the entire run without crashing on what is a ‘very tricky’ track layout.

Only 7th fastest in the opening seeding round, Hebert would make a big step forward with the performance of his Associated RC12R5.2 for CP2.  Bettering his fastest lap time by over 2/10ths and his 3-consecutive laps by almost 7/1oth, the Canadian said a stiffer centre spring ‘woke the car up’ adding it was ‘much better’ and had more steering.  He also attributed the extra speed to driving ‘more aggressive’ saying his car ‘could take that easy’.  ‘Super happy with (his) overall pace’, the 2014 5th place finisher summed up the car as ‘consistent and easy to drive’ adding ‘that seems to be the ticket’.  Team-mate Juho Levanen would also enjoy a stronger CP2 to post the 10th fastest time but with the low 46 car entry the former podium finisher will run in the second fastest heat.

The leading challenger of multiple champion manufacturer Yokomo, Ebukuro’s P3 time came in the first controlled practice.  Describing the overall feeling of his YRX12 as ‘getting better’, the Japanese National Championship runner-up said while others might be faster over a lap he will focus on consistency for the 8-minutes.

‘Everything OK’ was how Hideo Kitazawa summed his performance of the fourth best time which he set in CP1.  The Morotech driver & 2014 Podium finisher would suffer a broken diff in the final minutes of CP2 putting that down to the track being looser second time round.   Looking to Q1, he said other  than rebuild the diff he will leave his car unchanged adding the plan was to ‘go safe for the 8-minutes’.

Posting the 5th fastest time, reigning Japanese National Champion Hayato Ishioka described his performance as ‘so, so’.  Heading the campaign of reigning champion manufacturer CRC, the 20-year-old used the two controlled practices to back to back different tyre sizes.  Running bigger tyres in CP1, he would set his best three laps with them and trying smaller tyres for CP2 he said afterwards ‘bigger was better’.  Running Kimihiko Yano tyres and with no set-up changes planned, he is targeting ‘a consistent run’ for Q1.

sun_sobue

Making it a strong early showing for Japanese drivers in Beijing, Akio Sobue set the 6th fastest time to make it 5 Japanese in the Top 6.  The Tamiya touring car ace who is running for CRC in 1:12 scale, would post his best time in CP2.  Fitting a fresh LRP motor to his car for the first practice, he reverted back to the LRP motor he ran yesterday in free practice saying he thought it was better.  In terms of his car he confident ‘it is good for 8-minutes’ and with it ‘consistent’ he will keep it the same for Q1.

sun_marc

Summing up his performance as ‘consistent but too slow’, Rheinard said qualifying ‘depends on who crashes less’.  The German added, ‘Naoto is fastest but he is crashing a lot’.  Asked about his CP1 DQ, the time a 1/10th faster than his counting CP2 time, the Yokomo driver said, ‘we cut new tyres and forgot to get them marked just trying to be ready in time’.  With only an hour between runs due to the low entry, which is slightly up on that of the last Worlds held in the US, many drivers have complained about the lack of time to get ready between runs, the high tyre wear adding to the work load.  For his opening qualifier, Rheinard will run the car unchanged and just run ‘a little bigger tyre and try not to crash’.

Remarks – Canadian Associated driver Kevin Hebert is top Associated after practice running the well established RC12R5.2. Having raced on the ETS carpet back in January when he attended the Reedy race in the UK, he has based his setup on that experience, changing only his camber to get the car better in the middle of the corner. New on the car is the 510R speedo from Reedy which is a 2S speedo so they are having to run a booster for the received and servo. More information on the new ESC later.

Matsukura tops opening day at 12th Worlds

sat_naoto

Naoto Matsukura has topped the opening day’s action of the 1:12 World Championship in China where the biggest story is the lack of traction. Setting his fastest time in the fourth of the 8 rounds of free practice around the large technical indoor track in Beijing, the Japanese driver was fastest from Alexander Hagberg and Marc Rheinard with none of the top three able to improve over the second half of the day. The final practice would see slight improvement from Akio Sobue ad Keven Herbert, Sobue maintaining fourth and Hebert moving up to fifth but it was JJ Wang who would find the most time with a strong time in the penultimate practice that saw him complete the Top 6.

With Matsukura’s Roche clearly looking the fastest car on track despite his failure to better his best 3-consecutive lap times, the 3-time World Champion declared himself happy with the start to his quest to regain the title he lost to Rheinard two years ago. Summing up his day he said, ‘I’m happy, I have a super good feeling with the new car’.  Running a prototype chassis from the Hong Kong manufacturer, he said while the car is working the problem is the traction.  Describing it as ‘medium traction’, he continued ‘but I need high (traction)’ adding that the only way the traction could be improved is if they used a different additive, the race running a hand out controlled additive. Clearly still struggling with the rear of the car getting loose towards the end of the run, the practice runs 9-minutes long, he said he will not change his car set-up but instead run a large rear tyre for the first of tomorrow’s two seeding practices rounds.

‘Going backwards’ was Hagberg’s reaction after the final practice.  The reigning 3 in a row European Champion said he is ‘struggling to pace for 8-minutes’ adding ‘the track has no bite’.  Asked about the traction levels, the Swede said there was ‘no improvement’ saying it might in fact be ‘getting worse’ and that was ‘making it harder’ to find the right direction to take with set-up.

sat_marc

Rheinard shared a similar frustration with Day 1.  The Yokomo driver said, ‘we’re absolutely lost and have no idea what to do’.  Having got his car ‘super stable in the rear’, the German added it ‘understeers like a truck’.  Describing the traction as ‘strange’, he said they, ‘need to find the right tyre’ adding that the low traction means the event is going to be ‘pretty much a tyre game’.

Making front end changes to his CRC, Sobue said the car was ‘more consistent’ but for tomorrow he needs to find more steering. Planning to rebuild the car after its 8 practice run, the Tamiya touring car ace said a fresh diff should help give him some of the extra steering he is looking for.  In addition the Japanese driver will make a camber adjustment.

sat_hebert

Changing to a softer centre spring and a harder rear tyre, Herbert said these made his Associated ‘definitely better’.   ‘Better balanced’, the Canadian said the negative of the change was it ‘now pushed more’.  Overall ‘much easier to drive’ he said the found the right direction with the set-up but ‘maybe went a step too far’.  Looking to tomorrow, when the first of the qualifiers will take place after controlled practice,  the Canadian said, ‘it’s all about 8-minutes without crashing, it so tough out there’.

sat_bodywang

Driving his Xray for the first time, having previously raced Roche, Wang put his improvement down to trying ‘different tyre combinations’.  Having not changed his set-up much over the day, the Chinese American said, ‘tyres are everything’.   Feeling his car is getting there in terms of where he would like it to be he said, ‘I’m not really worried about pace because it’s the 8-minutes that counts’.  Behind Wang, Hideo Kitazawa would end up 7th fastest failing to improve on his P4 time while behind him Japanese Champion Hayato Ishioka slightly improve in P8 but stayed 8th followed by Toto Ebukuro and Andy Moore.
