The new E4JS is targeted at a racer who is interested in getting into electronic race racing but is conscious of his or her budget. Everyone has their limits and to be completely honest, it’s understandable, because by the time, motor, ESC and radio gear are purchased; the total cost of getting into on road electronic racing can be quite frightening for many.
Thankfully, the new Team Magic E4JS is giving many the opportunity to race a professional racing chassis for minimal cost.
Let’s take a closer look at some of the incredible features of the new E4JS.
Unique Super Low Friction 3 Belt Transmission:
An unique design feature of the E4JS 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 E4JS is exactly the opposite which meant no compromises!
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 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.
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 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.
Flying Wing Suspension Arms:
An exclusive design from Team Magic is the Flying Wing Suspension arms found on the E4JS. 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.
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 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.
Super Easy Maintenance
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.
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.
New single O-ring shocks minimize drag for smoother more precise dampening.
New Thickened Flying Wing Arm
Redesigned lower arms with thicker cross section for durability.
Speedo & Motor Vent Mount
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
Single bell crank steering system with increased Ackerman angle for instant response and crisper turn in.
Alum. 7075 Front & Rear Universal Joint
Redesigned 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.
