Back in October 2006, pictures of Team Magic's up and coming on-road electric touring car were beamed around the world via the internet. As an early prototype, it immediately captured the attention of the R/C world. From its unique styling to its complex nature, every part of the car was totally unique and offered an insight into where touring car chassis design was heading. Eleven months on, and Team Magic have quietly continued to develop and enhance the new car until it has reached its current state. With testing complete, it's time for Team Magic to introduce the latest step forward in electric touring car technology; the Team Magic E4.
Unique Super Low Friction 3 Belt Transmission: Another unique design feature of the E4 is the introduction of a 3 belt
transmission. It was chosen because of its advantages in motor, battery and
radio gear placement. In a classic two belt transmission system, the front belt
is centered down the chassis. This layout restricts the design of the car
greatly and forces the manufacturer to compromise in componentry layout. The E4
is exactly the opposite which meant no compromises! Team Magic has also included a beautifully machine aluminum front dual action
one-way/spool differential. With the pins inserted the differential acts like a
spool. Remove two pins and the diff turns into a one-way. This allows the driver
to customize the transmission to suit individual track requirements. In addition
to this, the pulleys and center mount are also machine from the same high
quality aluminum for improved pulley and belt durability. The rear of the car
features a fully adjustable ball differential. The whole system is set in motion by super low friction belts. The placement
and size of the teeth on the belts were designed to be a perfect balance between
durability and low friction. All in all, the advantages of the three belt transmission system outweighed the minimal increase in transmission friction. Top speed can be easily found, lightning quick corner speed cannot.
Centralized Componentry For Perfect Side To Side Balance: 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.
Flying Wing Suspension Arms: An exclusive design from Team Magic is the Flying Wing Suspension arms found
on the E4. 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 E4
designers with an opportunity to remove or shape excess plastic from around each
arm. Both options offer interesting benefits to improving the E4's performance. The 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 E4'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 E4 cut through the air, reducing its drag co-efficient dramatically.
Super Easy Maintenance 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 E4 chassis. From the wheels up, the E4 is the ultimate user-friendly touring car on the market.
Ultra Low Center of Gravity. A 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 E4 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 E4 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. The battery pack, which is inserted into the chassis from the bottom of the
car, receives the same treatment as the motor. Held in place by an aluminum
battery tray, the cells are just fractions of a millimeter from being flush with
the bottom of the chassis, but at the same time, totally protected. The aluminum
tray also aids in dispersing heat from the battery pack. With the battery being inserted from the bottom of the car, Team Magic's designers were able to lower the top-plate too. This in turn, meant the gearboxes, bulk heads, differentials and steering system were able to follow the same pattern. A low center of gravity chassis gone to the extreme.
Have no doubts about the E4, its unique and fast, all in one convenient package! We look forward to bringing your more details of the E4 soon. E4 Main Features:
