Sliding inner curve and Group B

We take look at the SCX Group B set of cars and the venerable snow curve which puts racers into a tight corner with low traction. However before you start talking about the cars lets take a look at what Group B actually was in the 1980’s.


Group B was introduced by the FIA in 1982 as replacement for both Group 4 (modified grand touring) and Group 5 (touring prototypes) cars.

Group A referred to production-derived vehicles limited in terms of power, weight, allowed technology and overall cost. The base model had to be mass produced (5000 units/year) and had to have 4 seats. Group A was aimed at ensuring a large number of privately-owned entries in races.


By contrast, Group B had few restrictions on technology, design and the number of cars required for homologation to compete—200, less than other series. Weight was kept as low as possible, high-tech materials were permitted, and there were no restrictions on boost, which turned out to mean almost unlimited power. The category was aimed at car manufacturers by promising outright competition victories and the subsequent publicity opportunities without the need for an existing production model. There was also a Group C, which had a similarly lax approach to chassis and engine development, but with strict rules on overall weight and maximum fuel load.

Group B was initially a very successful concept, with many manufacturers joining the premier World Rally Championship, and increased spectator numbers. But the cost of competing quickly rose, and the performance of the cars proved too much, resulting in a series of fatal crashes. As a consequence Group B was cancelled at the end of 1986 and Group A regulations became the standard for all cars until the advent of World Rally Cars in 1997.

In the following years Group B found a niche in the European Rallycross Championship, with cars such as the Renuault 5 and the Lancia Delta competing. For 1993, the FIA replaced the Group B models with prototypes that had to be based on existing Group A cars, but still followed the spirit of Group B, with low weight, 4WD, high turbo boost pressure and staggering amounts of power.

However, a series of major accidents, some fatal, were blamed on their outright speed. After the death of Henri Toivonen and his co-driver, Sergio Cresto in the 1986 Tour de Corse, the FIA disestablished the class, which was replaced as the top-line formula by Group A. The short-lived Group B era has acquired legendary status among rally fans.

The Slot cars

Fans of Slots will love the old school detail which is prevalent in the SCX models. Thick rear tires add that sparckel in everyones eye. True to the ledgens these cars have authentic decals right down to the tire print on the wheels. 

The Lancia Delta: Has large aluminium-coloured twin exhaust pipe, the number plate on its white background, the red tail lights and the highly visible mud flaps are other noticeable features of this Lancia Delta S4. Her we too are the anti-roll bars and the figures of the driver at the wheel and the co-driver holding the route plan. Both of them are wearing gold tops to go with the car’s colour scheme.

SCX Lancia Track Trials

Like all the all wheel drives with double pinion motors, the Lancia Delta S4 displays excellent,
evenly-distributed traction, with no power loss on any of the wheels. The gearing on the two
axles gives equal power to each of them, although the difference between the front and rear
tyres gives the back wheels a touch more traction.
The tires have good grip, keeping this SCX® car on the road on the bends. It is not a very long
model in terms of either guide distance or wheelbase, so you will need to control effective
traction by taking bends carefully and putting your foot down as it comes out of them. A lack of
attention to this will see the car tending to skid out of control, dragged by a high, rather heavy
bodyshell which generates excessive inertias – and it is on bends in particular that these make
themselves felt.

The ARS pick-up guide with its flat blades has a very smooth feel to it, so that the car fits snugly
into the slot without too much pressure. It stays in there well and makes contact without any
difficulty. The motor, well mounted on the chassis, starts up well and piles on the revs fast. It
transmits power to the ground well thanks to a set of pinions and crown gears which, with a little
running in and relubricating, prove to be very smooth.
Overall, the Lancia Delta S4 performs on a par with the other SCX® all wheel drives, in a way
which has proven a lasting success over the years, by fulfilling the proper function of all wheel
drive: transmitting motor power to the ground in the most efficient possible way.

SCX Renault 5 MaxiTurbo:  Sponsored by Phillips / Renault Elf driven by G Barreras. This car will give you some great rally track action, fitted with Magnatraction, 4 Xenon front lights and rear lights, self centering easy change sprung guide, great under chassis detail so you can look good even when you crash, displayed in a clear crystal case for your collection. SCX slot cars are superbly detailed with some very innovative designs, please note this car is not suitable for SCX digital conversion, however this car can be converted to Scalextric or Ninco digital with a conversion chip or Ninco digital 40304 and don't forget your tune up accessories and lubricants all of which will improve performance. 

The Renualt 5 offers great track performance all with different performance characteristics giving unlimited usage. 

SCX Renault 5 Track Trials:

 The gearing on the axles gives equal power distribution and thick tyres gives the back wheels a touch more traction and look good. The tires have good grip, keeping this Renault5 on the road when taking the bends. It is  a very attractive model in red and can be said to one of the smallest SCX replicas in terms of either guide distance or wheelbase, so you will need to control effective traction by taking bends carefully and monitoring the behaviour coming out of a corner . A lack of attention sees you out of the race. The body is light and it is on bends in particular you need to have heads up. The contacts stay in there and make contact without any difficulty. As with the Lancia , the motor is well mounted on the chassis, and piles on the revs fast especially due to the light frame. It transmits power to the ground quickly. 

Super sliding inner curve set:

Yes its mouth full but so is the challenge if you race magnet less. The curve offers a great expansion package that deviates from the norm by introducing a different contact substrate with low traction. A super sliding curve set for driving on ice effect with the Track going from black to mud brown in the centre to splattered mud brown and white inner and outer edges with both lanes merge into one through the curve. This fits the rally cars perfectly as there wide tires came into play effectively in relation the normal cars we tested on the track. 

Set construction is plastic and assembly, as per the normal Analogue set with all the pieces included so that you can assemble it to the track being expanded.
