Team Magic E4JS – Smashing the
price vs. performance barrier!
The new E4JS electric touring car chassis from Team Magic has
removed the complex barrier between price and performance. No
longer can you consider a chassis manufactured from plastic
instead of carbon fiber, a low spec product when it features
stunning characteristics as found on the new E4JS.
From its intricate, but highly efficient transmission, to its
state of the art suspension geometry; the E4JS has everything a
full time racer could ever need. The design of the car follows
on from the already successful E4 series so there’s no need to
be concerned about its ability to take the chequered flag.
Let’s take a closer look at what the E4JS has to offer:
Value
The E4JS is now the benchmark when it comes to performance at
a low price. The high cost items like carbon fiber, titanium and
aluminum which supposedly make a top of the line electric
touring car are now no longer necessary.
In their place is high quality, super strong, plastics molded
to match the suspension geometry and weight distribution found
in every E4.
Don’t be fooled into thinking that plastic is an inferior
product when compared to carbon fiber. Apart from one or two
redundant characteristics found in carbon fiber, many of the
latest manufacturing techniques now incorporate carbon injection
to improve rigidity and durability.
Like it or loath it, plastic, even in the highest quality
form, is simply, cheaper to make. With the E4 surrounded in high
quality but low cost plastic, savings are then passed onto the
end-user.
Durable
As mentioned above, technology has advanced plastic
manufacturing ten fold. Plastics used today are far superior to
what has been available in the past.
The improved strength means the cars are now stronger and more
rigid then ever before. This additional strength means Team
Magic can pay close attention to non stressed areas of the car
and reduce the amount of material used in that area. This in
turn reduces the overall weight of the car and improves its
performance.
&
The E4JS also shares the same structural design as the E4RS and
E4FS so strength and durability are second to none. For example,
the E4RS and E4FS already feature upgraded suspension arms and
these items are already included as standard on the E4JS. br />
QQuality
Quality isn’t just about the type of materials used to
make a touring car chassis. It’s also about how the parts fit
together, how well these same parts work together and how the
car feels in the hand. Fortunately Team Magic is now masters of
their domain when it comes to quality and is now seen as one of
the top R/C car manufactures in the world.
MMany of the parts found on the E4JS have gone through
rigorous testing procedures to make sure they operate at their
most efficient for an extended period of time. It’s Team Magic’s
policy to provide their customers with the best quality package
they can.
What also gives you a good feel for the quality of the E4 is
how easy the car is to work on. Everything is where it should be
and the ability to maintain or access areas of the car is as
simple as it can get. br />
Upgradable
Although we high recommend the E4JS package as it is out of
the box, it does share the same structure and design as the
other E4’s in Team Magic’s range. This means that if carbon
fiber or aluminum is a requirement for your style of racing,
many of the same parts can be shared between chassis’.
&
This upgradability not only covers exchanging of parts but
also included option parts like sway-bars, springs,
differentials, etc. /p>
With these options available for the E4JS, the car is capable
of running on any surface and any track.
Main features of the E4JS
Transmission
The 3 belt, fully ball raced transmission system of the E4
chassis’ is what sets the car apart from the rest. The uniquely
designed system operates at maximum efficiency thanks to high
quality universal joints and low friction belts all made by Team
Magic. The 3 belt transmission offers huge layout benefits over
the traditional 2 belt design which means the battery can now be
placed closer to the center line of the car, helping to improve
the cars side to side balance. In addition to this, the motor
can also be moved toward the center line too.
All these small changes add up to one big improvement in
corner speed and cornering consistency. The E4JS has got to be
one of the best cars on the market to drive fast.
CCentralized Componentry For
Perfect Side to Side Balance:
With the belts out of the way, the designers got to work
tweaking weight distribution so both sides of the car were
equal. They focused on making sure the heaviest components, like
the battery and motor were either centralized on the chassis or
very close to it. After a few modifications, they achieved their
goal and the E4JS now has a perfect side to side balance. This
gives the E4JS another advantage through the corners by letting
the car change direction much quicker. With all the weight
placed in, toward the middle of the chassis the E4 also has a
very neutral feel and there's less chance of the chassis rolling
over. Now you can push the boundaries when it comes to corner
speed like never before.
As all the components moved inward, the main chassis plate
began to shrink. This reduced the overall weight of the car,
again, improving its performance.
Suspension
Another unique feature on all of Team Magic’s touring car
chassis is the flying wing suspension arms. Designed to improve
strength while offering reducing unsprung weight, the suspension
arms are some of the lightest and strongest on the market. A
small alloy rod helps improve strength and reduce suspension
flex for a more direct feel.
This new manufacturing process allowed Team Magic to reduce the
size of the suspension arms without sacrificing strength. A
lightweight, hollow aluminum rod gives the suspension arm its
potent strength and provided the E4JS designers with an
opportunity to remove or shape excess plastic from around each
arm. Both options offer interesting benefits to improving the
E4JS's performance.
TThe removal of excess plastic helped to not only lower the
chassis total weight but also meant the shocks didn't have to
cope with additional loads. This improved the E4JS's
acceleration and ability to cope with a bumpy track or surface.
Next, Team Magic set about shaping the arm to serve two
purposes; firstly the removal of any holes in the arm makes it
much easier for cleaning and secondly, the shape of the arm was
molded to help improve airflow. The airflow runs smoothly over
the arm and this helps the E4JS cut through the air, reducing
its drag co-efficient dramatically. br />
Fully Tunable
TThe E4JS is a racer at heart. Everything has been included on
the car to offer you the most amount of flexibility when it
comes to tuning it to your style or track. Anything that can be
changed on any E4 or other top of the line touring car can be
changed on the E4JS.
Inboard toe adjustment can be altered thanks to off-center
pivots. Roll-center adjustments can be made via turnbuckle
linkages and rear uprights. The list is huge, but to say that
anything and everything to alter the cars handling is included
on the E4JS would be very accurate.
The chassis also includes front and rear ball differentials so
tuning the car to multiple track surfaces shouldn’t be an issue.
The ball differentials are fully adjustable and are excellent
tools for altering the handling of the chassis too. br />
Smart Designs
A notable difference between the other E4 chassis’ and the
E4JS is the way the battery is inserted and removed from the
car. This operation is now handled from the top of the car
rather than underneath. This means the time and tools required
to insert and remove batteries is greatly reduced.
Thanks to the new chassis design, the E4JS is right at home with
hard cased LIPO battery packs. Two thumb screws hold the battery
in place without any need for Velcro or tape.

Let's take a closer look at some of the
incredible features of the new E4JS./strong>

Ultra Low Center of Gravity:
AA fundamental consideration in manufacturing a high performance
on-road touring car chassis is making sure the major components
of the vehicle are placed as close to the ground as possible.
This gives the car a low center of gravity for increased
cornering speed and improved road holding capabilities. The E4JS
is a perfect illustration how this can be accomplished with
creative precision.
The motor and battery pack can account for almost 40% of the
cars entire moving mass so it's critical they are given priority
in positioning. The motor area of the E4JS is machined away to
lower the motor a total of two millimeters past the top of the
main chassis plate. This may seem like a small gain, but with
this design the motor is potentially just 1mm away from the
ground. It would be impossible to get it any lower without
placing it in undue risk from potential damage. &
Super Easy Maintenance/font>
The fun doesn't stop there though because the E4JS is also an
absolute charm to work on too! The design of the car
incorporates quick and easy access to all of the high
maintenance areas of any on-road touring car. Take for example,
the front and rear differentials. Only four screws hold each
differential securely in place. Undo these 4 screws and you now
have the ability to lift the entire differential out of car with
ease. Make some changes or give it a clean, then drop the diff
back in, tighten up the 4 screws and you're ready to race again.
Nothing could be easier.
&
The same applies for the main layshaft which is also held in
place by only 4 screws. Slide the belts off the pulleys and lift
the entire layshaft out of the car. These quick maintenance
features flow right throughout the entire E4JS chassis. From the
wheels up, the E4JS is the ultimate user-friendly touring car on
the market. /p>
&
The ultra low center of gravity combined with the center-mounted
battery location minimizes roll and allows the car change
direction like no other before it. Each component has been
analyzed and redesigned to reduce static and rotational mass
without compromising strength and reliability. br />
New Shocks
AAlso included is a high quality set of alloy/plastic shocks.
New single O-ring shocks minimize drag for smoother more precise
dampening. The LX style shocks include derlin pistons and
silicon seals for excellent performance and durability while the
threaded shock bodies allow for the smallest of ride height
adjustment without the need for additional parts or tools.
Speedo & Motor Vent Mount/font>
Ducted air intake for motor and ESC cooling. A cooler motor
means more power, longer run time and longer magnet / motor
life.
&
Single Bell Crank Steering System/font>
SSingle bell crank steering system with increased Ackerman angle
for instant response and crisper turn in.
Alum. 7075 Front & Rear
Universal Joint/font>
RRedesigned CVDs are both light and strong . With the remove of
blade cover on the shaft, CVD drive pins are fitted over in
order to reduce friction and protect the outdrives from wear and
backlash.
The new Team Magic E4 is the surprise package of 2008. By
removing the expensive ‘ling’ of a touring car chassis and
including cheaper, yet just as effective, replacement materials,
you end up with the perfect club racers car.
It’s strong, fast and tunable… what else do you need?
