The IFMAR World Championship for 1:10th Electric Off-Road Cars (officially "IFMAR 1:10 Electric Off-Road World Championship"), is a world championship radio controlled car race hosted by the International Federation of Model Auto Racing (IFMAR). It takes place biennially on odd years since 1987 in its current format but inaugurated in 1985 as a championship for Stock (stock handout motor) and Modified class (modified motors and seven cells)It is considered by the radio-controlled modelling industry to be the most prestigious event in the calendar that a number of mainstream hobby and toy brands have fielded factory entries.
The International Federation of Model Auto Racing (IFMAR) is the world governing body of professional radio controlled car racing.
The event is open exclusively to 1:10 scale electric off-road buggies with those of 2WD and 4WD drivetrain, competing separately. These are characterized by its large wheels designed for off-road driving and enclosed single-seater bodyshell with large rear spoiler.
The 1:10 radio-controlled off-road buggy is a 1:10 scale radio-controlled dune buggy designed for off-road racing. These cars are originally based on their full-scale equivalents that are commonly found in desert racing. The buggies are split into two race categories, two (2WD) and four-wheel drive (4WD). These can easily be distinguished visually by their wheel size at the front. Cars are typically electric powered, but nitro versions do exist but are less common because racing classes exist for electric cars. The class is inexpensive and similar to a number of other classes, and this makes them popular with newcomers. The cars are also known as 1/10 off-road.
Two-wheel drive (2WD) describes vehicles with a drivetrain that allows two wheels to receive power from the engine simultaneously.
Four-wheel drive, also called 4×4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.
Despite taking place under the same host and venue, the two championships are regarded as separate events, therefore in between them, the circuit is required to be rebuilt and reconfigured differently.
All the world championships took place on dirt or clay tracks until 2015 when the decision was made to run controversially on artificial turf.
The 2015 IFMAR 1:10 scale Electric Off-Road World Championships is the 16th edition of the IFMAR 1:10 Electric Off-Road World Championship for 1:10 scale radio-controlled electric off-road buggies sanctioned by the International Federation of Model Auto Racing (IFMAR). It was run over two separate classes over eight days from 3 to 10 October, with each class running for three days each in total.
Artificial turf is a surface of synthetic fibers made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. However, it is now being used on residential lawns and commercial applications as well. The main reason is maintenance—artificial turf stands up to heavy use, such as in sports, and requires no irrigation or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy. Artificial turf does have its downside, however: limited life, periodic cleaning requirements, petroleum use, toxic chemicals from infill, and heightened health and safety concerns.
In the 2WD class Associated Electrics, holds distinction for the most wins for manufacturers with a total of 11; Masami Hirosaka of Japan, hold the record with three wins. In the 4WD class Yokomo holds distinction for the most wins for manufacturers; Hirosaka, holding the record with three wins.
Associated Electrics, Incorporated of Lake Forest, California is one of the world's leading manufacturers of radio controlled cars, trucks and accessories. Associated Electrics is now owned by Thunder Tiger Corporation from Taiwan. The company is usually referred to as Team Associated.
Masami Hirosaka is a Japanese radio controlled car driver who is considered to be the world's most successful with a record fourteen IFMAR World Championships in 1/12 scale electric, 1/10 scale Pan, 1/10 scale 2WD off road and 1/10 scale 4WD, all electric. Hirosaka's peers have nicknamed him "Master Masami". He was considered to be one of the highest paid drivers in RC racing, until he retired from the activity. His last IFMAR race was the 2008 world championship in Thailand. His retirement ceremony was on May 3, 2009.
Yokomo Co. Ltd. is a Japanese company from Adachi, Tokyo that specialize in radio-controlled cars, it was one of the first manufacturers in Japan to build RC cars and it also invented the RTR cars, but most notable of all is their long-running "Dog Fighter" series of radio controlled buggies, mainly through its successes in racing.
As it is considered by the industry to be the most prestigious event in radio-controlled modelling, in an attempt to "generate sale revenue from their products”,it has attracted some of the biggest brands from the hobby and toy industries that included Nikko, Tomy, Tamiya and Traxxas. Only the latter two had greater success at the A-mains with Tamiya achieving 2nd by Lee Martin in 2013 and Scott Montgomery's 8th for Traxxas in 1991, both in 2WD.
Nikko R/C is the largest toy-grade radio control manufacturer in the world. The company's licenses include those from Dodge, Ford, Volkswagen, Chevrolet, Porsche, as well as proprietary designs. In 2014, Nikko was acquired by global toy company, Toy State. In 2017, Toy State created a new arm of the Nikko brand, Nikko Air.
Takara Tomy Company, Ltd. is a Japanese entertainment company that makes children's toys and merchandise. It was created from a merger on 1 March 2006 of two companies: Tomy and long-time rival Takara. The company has its headquarters in Katsushika, Tokyo.
Tamiya Incorporated is a Japanese manufacturer of plastic model kits, radio controlled cars, battery and solar powered educational models, sailboat models, acrylic and enamel model paints and various modeling tools and supplies. The company was founded by Yoshio Tamiya in Shizuoka, Japan, in 1946.
At the 1989 Worlds, it was claimed by Radio Control Car Action that virtually every manufacturers, who had a 1:10 buggy on the market, was represented. In a bid to defend their 4WD title the same year; Schumacher, a title sponsor, handed out their latest car, the Top Cat, to any contender who was interested in representing them.
Schumacher Racing Products is a British manufacturer of radio-controlled cars and accessories with a primary focus on high-end racing products.
As a number of manufacturers spend a large sums of money to prepare their teams to ensure a win, as a result a number of those enforce secrecy to protect their prototypes from view. In one notable example, Team Associated, who was the only brand to field a prototype, refused to allow it to be photographed, covering their RC10 up with a towel on anybody who tried to and when forced an Australian team member to hand his film over as he managed to take a few shot of its exposed chassis during technical inspection. Losi in comparison managed to escape scrutiny as experimental two-speed transmission was kept secret and gave misleading answers to prying eyes. They switched to their conventional transmissions in the finals.By the time of the 1991 Worlds, this practice was enforced by a majority of manufacturers. This was in contrast to the 1986 IFMAR 1:8 IC Off-Road World Championship, when Japanese entrants from Kyosho clearly knew their outdated cars had little chance against their European competitors, freely took numerous photographs of their competitor's cars to benefit their research. The outcome became the Burns in late-1987 and then, at the turn of the decade came the highly successful Inferno series that dominated racing from then on.
To prepare for the 1989 event, Yokomo technicians famously collected soil sample on the track for analysis back in Japan. They were allegedly spotted by locals wheeling around the circuit, a cart that had a video camera mounted on it to get a car's eye view of the track. The end result was a duplicate of the track that became the Yatabe Arena back home.Nowadays, regulation require the circuit to be altered at over 60% of its layout, had it been used prior to commencement date and closed for a 2-day minimum, 3-day maximum prior to then.
Good preparation is key to winning as opposed to accessibility to prototype arts as Associated learned in 1993; when they felt their standard issue, aluminium chassis RC10 was best suited to the circuit, mechanics proceeded to modify Brian Kinwald's chassis by rounding its square edges. Its suspension arms was molded from a more rigid graphite.
Teams and drivers are prepared to bend rules in an attempt to win. In 1989, Yokomo's TR-31 tires, only made available to Yokomo and Associated drivers, became a subject of scrutiny due to its size, given the rate of speed its Yokomos and Associated were going.
The tires, were 2 1/4 inches tall (equivalent to 22 inch in full scale) which was illegal under ROAR regulation (maximum 2 inches) though IFMAR did not have such restrictions and was shipped in 30 boxes of tires from Japan. In comparison, Associated was quick to point out to the critics that at the 1987 Worlds, Kyosho fielded tires on its Ultima that was too wide for ROAR regulations.
Team Losi in retaliation, countered this by taking all the stops in the States to produce and ship over 100 pairs of oversize front tires, 200 pairs of rears and five sets of hand-machined aluminum wheels across the Pacific. The tires, only permitted on its JR-X2, ended with mixed results for drivers as the rim ended up being bent out of shape and discarded for Losi's standard wheel.
Some who attempted to bend the rules were not lucky such as at the 1993 Worlds; the electric motor of Ben Sturnham's Schumacher CAT 2000 was found with a hybrid motor illegal under IFMAR regulation regardless if it was compliant with the host country BRCA's regulations, his Tanaplan motor consisted of parts by other manufacturer of approved motors including Epic can and armature with Yokomo endbell. Sturnham had his 3rd-place finish demoted to a 10th place after all his lap times was removed despite protests by Tanaplan's Martin Finnesey that it offered no performance enhancement.CITEREFHowell1993
A maximum of 150 drivers take part, each continental blocs allocated 32 entries each, the host bloc an extra 10 and the final 10 allocated by IFMAR themselves; should any allocation be left unused, it would be reallocated to the remaining blocs. The event take place over eight days in total with the first reserved for competitor's registration followed by its opening ceremony in the afternoon then the two sets of three days for competitions.
The competitions begin with a minimum of six practice rounds over groups of fifteen consisting of ten drivers each, starting with the less experienced, this determine the number of heats required and the minimum time needed between rounds.Each heats consists of drivers who are ranked in order of priority; final ranking in the previous Worlds, then those of each countries and the domestic entrants and additional entries. In this case, in the 2015 Worlds, debutants Spencer Rivkin and Bruno Coehlo started at the lower-to-mid practice group 6 and 11 respectively, whereas Steven Hartson, Jared Tebo, Naoto Matsukura and Lee Martin start together in group 15 as the former two are defending champions and the latter given their performance or seeding in their home blocs whereas Travis Amezcua and David Ronnefalk, despite appearing at the A-main once previously, starts in practice group 14. Usually the final rounds are used as controlled practice. At the 2015 Worlds, practice rounds consisted of four rounds of open practice and two rounds of seeding practice to group the drivers together by skill levels. The second day of competition, following the second controlled practice, consists of four rounds of qualifying heats and for day three; the final qualifying session and race day. For each qualifying session, a group of up to ten cars start under the "staggered start" system (a driver each starting separately within of one second of being called).
After each 5 minute qualifying session, the best qualifier of the round is awarded zero points, 2 and 3 points for the 2nd and 3rd fastest qualifier and so on with the most points given to the slowest qualifier. Of five rounds in total, the best three overall performances (as opposed to lap times in full-sized motorsport) counts toward the driver's overall performance, two best rounds counts toward three or four rounds completed and one round count toward two or one rounds. After all the points is totaled up, the driver with the fewest points is the best qualifier, thus is awarded a TQ (Top Qualifier) spot, enabling them to start in front of each rounds. Should they tie in points with another driver, the one with the lowest points score of the three is used to break the tie, if this fails, then the next set of points will be used until the tie is broken. If the points fail to break the tie, then the driver's laps and time from the lowest score will be used.
The groups are then split into ten groups of ten drivers in alphabets, pending on their performance in qualifying with A being the fastest of the groupsRace day starts with the slowest groups first, working its way to the next faster groups up to the fastest, the A-main, then progresses to the 2nd heat. Each race run for a total of five minutes with an extra time to allow the driver to complete their laps. Only the A-main, the group that carries the only hope of taking the world championship title, have three heats with only two best performances that counts and a final practice in the afternoon during race day and the rest run under a single 5 minute heat.
Following the conclusion of the first championship, the event will have an off day as the circuit would have to be rebuilt and reconfigured to a different layout required by IFMAR regulations as accordingly the two Worlds are considered to be a separate events.The practice would instead start with drivers who are ranked according to their performance in 2WD the day before.

Remotely Operated Auto Racers, abbreviated as ROAR, is the sanctioning body of competitive radio-controlled car racing in the United States and Canada. ROAR was originally organized in 1967 By George Siposs and Norb Meyers and a small group of people dedicated to forming competitive Radio Controlled Car Racing and was the first organization in the world to sanction competitive Model Car Racing. In 1968 the first ROAR National Championship race was held at Sunset Ford car dealership in Garden Grove, California using 1/8th scale nitro pan cars. ROAR has steadily grown and evolved as the sport has grown. ROAR is the oldest sanctioning body in the world.
