Chassis Focus – Keven Hebert

Chassis – Associated RC12R5.2
Motor – Reedy Sonic 3.5T
ESC – Reedy 510R
Battery – Reedy 8000mAh
Tires – JFT
Radio/Servo – Futaba
Body – Protoform AMR

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.

Chassis Focus – Akio Sobue

Chassis – CRC Prototype
Motor – LRP X210 4.0T
ESC – LRP Flow
Battery – LRP 8100mAh
Tires – CRC Japan
Radio/Servo – Sanwa
Body – Protoform AMR

Remarks – Japanese race Akio Sobue is running a new CRC prototype chassis here in China, which he previously ran at the Japanese Nationals. Sporting new chassis, motor mount and servo mount he has had to change his setup from what he normally runs for the lower traction including a front camber and centre shock change. Like many here, he is suffering with his car in the last minutes of the run and will go out with larger tires, he is also changing his front additive application time from 1 minute to 10 to get more traction.

Chassis Focus – Naoto Matsukura

Chassis – Roche Prototype
Motor – Muchmore Fleta ZX 3.5T
ESC – Muchmore Fleta Pro
Battery – Muchmore 8000mAh
Tires – Team Bomber
Radio/Servo – Sanwa/Xpert
Body – Protoform AMR

Remarks – 3-time 1/12th World Champion Naoto Matsukura is running a prototype chassis from Roche. Having also tested in Korea on the ETS carpet the Japanese driver has since changed his setup upon arriving here, making the side springs harder for faster response from the car. Also suffering from high tire wear, he will look at running larger diameter tires so he will have some rubber left at the end of the run. Struggling a little with understeer Naoto has changed up his saucing routine, going from 10 minutes for the front tires and an hour on the rear to 30 minutes on the front to help gain more steering.

Chassis Focus – Marc Rheinard

Chassis – Yokomo YRX12
Motor – Muchmore Fleta ZX 3.5T
ESC – Muchmore Fleta Pro
Battery – Muchmore 8000mAh
Tires – Yokomo
Radio/Servo – Sanwa/Xpert
Body – Protoform AMR

Remarks – Reigning World Champion in the 1/12th scale class, Marc Rheinard is racing the YRX12 chassis from Yokomo here in Beijing. Having tested on ETS carpet in Korea back in July in preparation for this race, he says the traction is lower here as the carpet is new and this is causing the car to slide around which means tire wear is high. Focussing on tire diameters to find the perfect balance, once that has been sorted he will move onto the perfecting the car’s setup.

RC Racing’s biggest prize is to be decided in the world’s biggest economy for the first time as China plays host to the 18th running of the 1:12 IFMAR World Championships.  Held in the Fengtai district of Beijing, the indoor race, which will be followed later in the week by the outdoor Electric Touring World Championships, is taking place at the Fengtai Sports Centre.  Built originally to house the softball stadium used during Beijing’s hosting of the 2008 Olympic Games, the centre is also home to the Fengtai Science, Technology and Sports building in which the Car Modelling Association of China have built an superbly presented temporary carpet track.  Such is the level of organisation for the Fengtai government funded running of the World Championships there is a staff of 30, half of whom are volunteers, to look after the 56 entries which is actually a 25% increase on the entries for the last 1:12 World Championship which were held in the USA.

Under the guidance of the Race Director Max Lim, the 6-day build has resulted in a meticulously detailed track that covers and area 30 metres wide by 24m deep. Positioned 4 metres in front of the driver stand, the layout was penned by Lim who said much of the track’s influence was based on driver feedback who favoured ‘a more technical’ layout. Using ETS black carpet, which they had brought in especially from the Netherlands, Lim said the considerable depth of the track has allowed the layout to also be ‘really fast’.  As a structure, the track sits 15 centimetres off the ground with each square metre of the track standing on 4 feet.  As lane dividers the track uses locally made plastic box piping which has been screwed into place.  Cut to 1-metre lengths Lim said this allows for quick & easy replacement should they get damaged by cars, him adding ‘we used this material so it takes the impact rather than breaking the cars’.   With the hall having 5 rows of sky lights providing natural light, this also presented a shadowing problem.  With the addition of banks of lights not a option as the building’s roof is not certified for the weight load, two star shaped light balloons hang above the track instead.  With two 2kw bulbs in each they provide a well defused light.

Giving his first impression of the track, reigning World Champion Marc Rheinard described it as, ‘a pretty nice track and it’s a good size’.   With the early fastest lap times in the region of late 12-seconds, the German continued, ‘the layout is tricky, there are many chicanes and everyone is crashing.  I think consistency is the focus rather than being fastest over a lap because every time you crash you risk tweaking the car’.  Thinking further ahead, he concluded, ‘its missing some passing points for the finals’.
