Chassis Focus – Yusuke Suguira

Fri-SuguiraZX6-1

Chassis: Kyosho Lazer ZX6
Motor: Muchmore Fleta 5.0
ESC: Muchmore Fleta Pro
Batteries: Muchmore 4500
Radio/Servo: Sanwa
Body – Lightweight Kit body

Remarks – Current 4wd pace setter Yusuke Suguira is running his Kyosho Lazer ZX6 with a number of option parts on the car. Having tested extensively at the Yatabe Arena’s permanent astro track in the lead up to this race he is running his base setup here in practice with just a few small tweaks. In terms of new parts on the car Yusuke is using new shock towers front a rear that have higher shock mounting points that allow the car to run a lower ride height while maintaining the shock’s full travel. The chassis also has a rear stiffening brace for better flex characteristics and finally there is an unspecified update to the car’s drivetrain.

Chassis Focus – Bruno Coelho

Thurs-CoelhoXB416-1

Chassis: Xray XB4 16
Motor: LRP 5.5
ESC: LRP Flow
Batteries: LRP 4500
Radio/Servo: Sanwa
Body – Kit body

Remarks – European Champion in 1/10th 200mm and surprise 2wd pace setter at the opening round of the EOS, Bruno Coelho was fastest in free practice and 2nd after controlled practice here in Japan with the all new Xray XB4 16.  The car, which is the final production model, sports an all new aluminium chassis plate with no top deck, the latter being replaced with carbon braces mounted to the centre of the chassis plate. The weight in the car has been moved forward by moving the motor and electronics closer to the front, the result being a car that carries a lot of speed in the corners yet is very easy to drive. Other changes include new front wishbones with different inner pivot pin position, reinforced gearbox cases front and rear and an all new bodyshell.

Sugiura is top seed at WC

thu_sugiuratopseed

Yusuke Sugiura is the top seed for qualifying at the 1:10 4WD Offroad World Championships in Japan.  The Kyosho driver set a new fastest 3-consecutive laps time in the second of the controlled practices to secure the No.1 in the top heat for qualifying tomorrow at the Yatabe Arena.  Behind the Japanese driver European drivers Bruno Coelho and Michal Orlowski would also improve on their CP1 times to end 4WD Day 1 2nd and 3rd fastest respectively.  Fastest in the first round, Jared Tebo failed to improve second time of asking and will carry the No.4 for qualifying followed by Martin Bayer and Ryan Cavalieri.

Declaring himself ‘happy’ to end the day fastest, Sugiura said he ‘still made mistakes’ adding he has ‘got to be much better for qualifying tomorrow’.  Describing his Muchmore powered Lazer ZX6 as ‘very fast’, the 19-year-old former Japanese National Champion and Warm-up podium finisher said it is ‘completely down to the driver now’.  Expecting the track to change over four rounds of qualifying on tomorrow’s schedule, the fifth & final round running Saturday morning, he said he prefers the lower grip of the morning but said his car is good in both conditions.

Making his 1:10 Offroad Worlds debut, Coelho said he didn’t just focus on 3-laps but his 5-minutes pace in the last practice.  Making two mistakes as he ‘over pushed’ he said ‘otherwise (he) was very happy with the consistency of (his) lap times’.  Running new tyres on his LRP powered XB4 for CP2, the better known onroad star said his buggy worked really good which surprised him as he didn’t expect this on the fresh tyres.  Pleased to get in he top group for qualifying he thinks this should be good but admitted ‘3-laps means nothing’ and its going to be ‘super difficult’ to stay there over 5-minutes’.  Bayer would suffer a motor issue in the final practice, but the Czech driver who was second fastest in CP1 is confident that with a new motor fitted he has a good car for qualifying.

Ending up only 0.065 of a second off Sugiura, Orlowski was pleased with the result but said it didn’t come easy.  Having struggled with a twitchy car in CP1, ending up 7th, he had put this down to his Schumacher being on new tyres.  Running them again in CP2, he said the car was no better and he had to reduce the steering EPA in the warm-up.  Taking the approach to drive smoother he said that worked out good but at the same time he got unlucky as on one of his counting three laps he had to avoid a crashed car costing him a few tenths.  Planning to change his wheelbase for the practice run that opens tomorrow’s qualifying day he said hopefully that settles his buggy, adding a good & long night of sleep should also help with the 14-year-old feeling ‘super tired’.

thu_tebotable

Asked if he had sorted his ongoing brake issues Tebo replied ‘not yet’ adding ‘we’ll get it figured out for tomorrow’.  The Kyosho driver said ‘the car is really good so we’ll be all good’.  Kyosho team-mate and a driver many expected would have a home advantage on the first Worlds to be run on astro turf, Touring Car World Champion Naoto Matsukura would fail to better his CP1 time scraping into the top heat along with 1:8 World Champion Ty Tessmann who posted his first Top 10 time in the final practice.

thu_cavalieri copy

Another driver to count his opening time, Ryan Cavalieri completed the Top 6.  The Associated driver said a small adjustment to the breakthrough set-up he used in CP1 had made his Orion powered B44.3 ‘too conservative to drive and he will go back’ for tomorrow. Feeling he is in the mix over 5-minutes he said ‘its going to be interesting for sure but we should there’.  After the high of being crowned 2WD World Champion on Tuesday, Spencer Rivkin suffered a challenging first day of 4WD.  The 16-year-old could only manage 37th, a time set in CP1 when he broke with 2-minutes remaining, and put the poor performance down to just not having found a set-up yet.  Getting closer to Cavalieri’s setting he said ‘we’ll figure it out’ but lining up in the fourth fastest heat traffic could prove an issue in qualifying. Reigning champion Steven Hartson didn’t fare much better ending the up 28th.

For home manufacturer and Yatabe Arena owners Yokomo, Lee Martin would finish the seeding 7th ahead of top HB driver and fellow European David Ronnefalk.  The Euro Offroad Series Champion said his last run was ‘not too bad’ and he was on a 5-minute run as ‘3-laps count for nothing’.  Feeling he ‘should be OK’ in terms of pace his plan is to ‘try and keep it on its wheels’.  The British driver however expects ‘a bit of carnage’, continuing ‘its so fast there are going to be crashes and in 4WD crashes are big’ plus there are a few mad men in there too’ not being specific about which drivers he was referring to.  Just missing out on a Top 10 time, Ryan Maifield was best TLR driver ending up 11th.

Tebo tops open controlled practice

thu_tebo

Jared Tebo has topped the opening controlled practice at the IFMAR World Championships in Japan, the Kyosho driver setting the fastest 3-consecutive laps of the Yatabe Arena over the Xray of Martin Bayer. Having set the pace in free practice, Bayer’s team-mate Bruno Coelho would complete the Top 3 with just 4/10ths separating the Top 10 drivers.

thu_jaredjorn

Having ended free practice 6th fastest, Tebo would improve his time by 3/10ths to repeat his 2WD performance when the American also topped the first of the two practice rounds that will determine the heats for tomorrow’s qualifying.  Pleased to top the times for the first time in 4WD, the former Champion said ‘the whole run was awesome but I’m still looking for better braking’.  Having fitting a new speedo to eliminate that being a cause of the problem he said the braking was no better.  The issue is when he applies the brakes they take varying time to come in causing him to miss his lines.  Planning to switch to a gear diff with thicker oil for the day’s final practice, he said better brakes would make him more comfortable with the car which he said can be ‘a lot better’ once he gets the issue sorted.

thu_bayer2

Only 13th fastest going into the first controlled run, former European Champion Bayer was happy ‘super happy’ with second.  Posting the fastest lap time, the Czech ace said himself and Coelho having been trying different set-ups to each other every run for CP1 they had the same set-up, one which he said was pretty close to the base set-up they came into the event with.  Describing his ORCA powered XB4 as ‘super easy to drive’ the EOS race winner said he ‘just drove it around’.  Running in Heat 11 of 13, the groups sorted based on the result of Tuesday 2WD finals, Coelho said he had a lot of traffic and he couldn’t get a perfect 3-laps.  Despite this he said 3rd was good with his aim for practice to just get placed in the top heat for qualifying.

thu_carsugiura

Posting the fourth fastest time, Yusuke Sugiura described his performance as ‘so, so’.  Having raised the ride height of his Kyosho, the factory Kyosho driver said while the car was better he felt his own driving needs work.  Planning to leave his buggy unchanged for CP2, the 19-year-old will working on his consistency.  Team-mate Naoto Mastukura would take his example of the Lazer ZX6 to the 8th fastest time. The Warm-up Race winner & 2013 Worlds Runner-up said a set-up change was ‘not good’ and he will now revert back to his P3 set-up with a little tweak.

thu_ryancav

‘We made it to the show and showed up for one run’, was a much more upbeat Ryan Cavalieri reaction to setting the 5th fastest time.  Winning the last of his three 4WD World titles in 2011, the Associated driver said after ‘struggling with not enough low speed steering’ his B44 was ‘a lot easier to drive and on pace’.  Getting the improvement through changing a ‘bunch of little things’ he now said they have a good base to work from and fine tune.  It wasn’t all celebration in the AE camp however with the next of their drivers being Kyle McBride in 15th with new 2WD World Champion Spencer Rivkin doing only half the run and ending up 28th.

thu_carronne

Making a substainal gain to knock 6/10th of his previous best, David Ronnefalk would complete the Top 6.  The factory HB driver said his D413 has been ‘really good from the beginning ‘.  Running his EOS set-up he said it was fast but too aggressive and they have managed to tone it down by adjusting the rear end set-up.  Running in the fifth fastest heat, having made only the F-Main in 2WD, the Swede said his 5-minute pace was also good enough for Top 5 even with lots of traffic so he is hopeful if he can get a better heat for qualifying he can be even closer to the lead pace of his former team-mate Tebo.

thu_michal

Third fastest at the end of practice, Michal Orlowski would set the 7th quickest time describing the run as only ‘OK’.  Running a new set of the controlled tyres he said they made his Schumacher very twitchy with ‘no grip in the rear’.  As a result the Polish ace said it was difficult to drive and therefore he lacked consistency.  Planning to reuse his tyres in CP2, the European Champion will leave the set-up unchanged having been very happy with his CAT K2 on used tyres in the final free practice.  Orlowski’s old Durango team-mate Travis Amezcua, who was 7th in free practice would shut down in CP1.  Managing to post the 13th fastest time during the less than 3-minutes he ran, the American believes the shutdown was caused by his receiver as turning off and back on the car everything was working again.

Chassis Focus – Ty Tessmann

Thurs-TessmannD4-1

Chassis: HB D413
Motor: Orion VST2 Pro 4.5
ESC:Orion R10.1
Batteries: Orion 4o00
Radio/Servo: Futaba/Savox
Body – Pro-Line Type R

Remarks – Current 1/8th scale World Champion Ty Tessmann is running the HB D413 with a number of option parts to make it work better on Astro. The backbone of the car is the new 6mm longer chassis plate and thicker top deck to make the car stiffer. In the drive train the centre diff has been changed out with an as yet unreleased slipper put in its place which is better in high grip conditions. In the front there is a new ball raced aluminium steering rack while both front and rear there is new diff cases that have higher hinge pin mounting points that allow the car to be run with lower ride height without changing the car’s resting geometry.
