car racing has been around for more than 40 years and has changed very
little in that time. Basically, only one car can be raced in each
slot (or lane) and to race 6 cars together at the same time requires a
track with 6 lanes which is very wide and impracticable in most private
homes which is where most racing takes place. Also, in a turn, the car
in the outer lane travels in a very wide radius turn whilst the car in
the inside lane travels in a very tight radius turn. This is not at
all like real motor racing. Recently, some improvement has been made
with the introduction of 'Digital' slot racing whereby up to 6 cars can
be raced on a 2 lane track and lanes can be changed at designated
points around the track but there is still much room for improvement
controlled model car racing is also a well-established hobby and radio
controlled model cars can nowadays be manufactured in very small
scales, I.e. down to 1/32 scale similar in size to slot cars, and this
would seem to be the answer except for one major problem. For various
reasons of scale time, friction, air drag and human reaction times,
driving such small models accurately is virtually impossible. Tracks
need to be at least 60cms wide and even then overtaking without a
collision cannot be guaranteed and following the racing line through a
corner is almost impossible. Watch videos on YouTube such as,' Mini z outdoor oval' and you will see what we mean!
takes the best elements of both these systems and, with new technology
and innovation, solves or improves upon all of these shortcomings. The
cars are guided basically by a magnet following a steel wire embedded
in the track. They can be steered from one side of the track to the
other by radio control at selected but easily and cheaply fitted lane
change points. Speed is controlled by the pistol trigger and cars are
powered by a single rechargeable Lithium ion cell. Run times are in
excess of 20 minutes using a single AAA cell which is inexpensive and
quickly recharged. The battery is located underneath the car, held in
place by a magnet (patented) and, for a pit stop can be changed in less
than 5 seconds! There would normally be two guide wires around the
track forming two lanes and up to 15 cars can be raced together by
selecting different radio frequencies. Cars can change lanes to
overtake, can be steered to take the fastest line through each turn by
approaching in the outside lane, turning early to clip the apex and
finishing back on the outside of the track. They can also turn into the
pit lane when required. All this on a track of only 7” (16cms) wide
with no slots, pick up tapes or lane change points to spoil its
The speed of the cars is much closer to
scale speed ( perhaps 200mph!) so in action they look much more
realistic than slot cars or indeed 1/12 scale free running r/c cars.
Because the front wheels steer, we again see greater realism. When
driven too quickly, the cars will either spin or under-steer off the
track. This is of benefit because, if the car runs completely off the
track, it cannot block following cars which often happens with digital
slot racing. Cars are steerable when away from the guide wire and, with
the introduction of reverse (March 2103) can be steered back on to the
track after almost all crashes. This means that marshals standing
around the track are no longer required. This is a major advance over
slot-racing and indeed over early Magracing
The idea of steering vehicles by magnet and guide wire is not new but
what is new is this systems ability to change from one guide wire route
to another. This is achieved by removing a short length of the guide
wire at the desired lane change point and replacing it with a patented
flat plate. At this point, it is then possible to change the direction
of the car by means of a radio controlled actuator in the car. This
steering actuator turns the wheels just sufficiently for the car to
leave it's straight line course and to realign with another guide wire.
This wire can then lead the car to the alternative lane or to the
fastest line route around the turn or to the pits lane, etc.. If the
driver inadvertently turns the steering the wrong way ( quite easy for
a novice driver!), the car will not leave the track and crash but will
continue straight ahead. The steering must be actuated (i.e. the
steering wheel turned) before the car reaches the lane change point and
held until after the L/c point has been passed.
This track system is extremely simple and inexpensive to construct and maintain.
A racing scenario would see up to six cars running on the two lanes. If
two cars approach a turn side by side, the driver in the outside lane
must forgo the fastest line route and stay in the outside lane. As well
as looking more realistic, speeds have been deliberately restricted to
allow drivers time to make these decisions. Acceleration and braking
rates are also restricted nearer to scale to allow cars to race much
more closely to each other. During a lap of a typical track, Linford
Two for instance, a driver has 12 lane change and racing line options
to consider in approx 10 seconds in addition to speed control and
awareness of up to maybe 5 other cars on the track. Pit lanes are easy
to include and battery changes are a feature of longer races.
As in full size motor racing, it is necessary to
learn the track . Small arrows are painted on the track to indicate
where the lane change points are but at racing speeds the driver must
Early tracks used 2mm diam wire in routed slots but this has been
progressively reduced and we now recommend 22swg (.028”, .07mm) piano
(music) wire glued to the baseboard and the track level raised flush
with plaster (quick but messy!) or more slowly but cleanly by infilling
with panels of low cost card of the same thickness cut to shape and
stuck down. Lane changes require careful positioning of the flat lane
change plate and the enter and exit guide wires but the cost of a lane
change is almost nothing compared to that of a digital slot lane
change. A track could be as small as 3feet x 6 (1metre x 2) but larger
tracks enable greater use of MAGracing's features.
The radio control equipment has been purpose designed for MAG-racing.
Proportional steering is not needed as the lane changing and racing
line steering is effected by means of an electromagnetic coil Speed
control is fully proportional. Range is adequate with antennae of only
90mm easily hidden within the cars. Cars and radio transmitters (txs)
are both powered by the same AAA rechargeable cells.
Cars are 1/32 scale, similar to the most popular slot racing scale.
Motors are purpose built high torque 3.7 volt. Body shells are High
Impact Styrene mounted with magnets giving instant removal and
replacement. Body removal is only necessary for maintenance or for
steering magnet ride height which may be easily adjusted if necessary
to suit differing tracks which may or may not be smoother than your
supplied are deliberately low grip to reduce cornering speeds thus
increasing the skill required and ensuring that cars cannot be driven
flat out around the track.. Tyre dressings/additives can easily be
added to increase grip and details are included in the tyres section.
This makes the cars easier to drive for novice drivers but can remove
the skill for experts. MAG-racing driving does take some time to learn
and most people will need a couple of evenings to master it. For this
reason MAGracing is unlikely to prove suitable for 'Pay as you go'
A fifteen car system has been developed and will be available shortly.
This is a revolutionary new r/c race system made possible by new
technology and innovation. It is not envisaged as a replacement for a
slot racing set for 5 - 10 year olds set out on the home floor but as a
new hobby for adult model car or motor race enthusiasts who appreciate
the greater realism and driving skills which this system offers and who
are prepared to devote a small but permanent space for a race circuit
where individual enjoyment or serious competition can take place.
Unlimited challenging track features can be included for those
interested in the racing aspect and more realistic scenic effects can
be included by those looking for greater realism.
