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.
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.
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.
Flying Wing Suspension Arms:
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.
Centralized 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 E4 now has a perfect side to side balance. This gives the E4 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.
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.
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.
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.
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!
Unique Super Low Friction 3 Belt Transmission:
Let's take a closer look at some of the key features of the E4 -- the ultimate on-road racing machine:
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.
