之前就E4FS,今次就E4RS,主要都係海綿呔版本同膠呔版本O既分別嚟~
A short time ago Team Magic left their comfort zone of producing the most competitive line of 1/10 scale onroad cars on the planet. They ventured into the realm of onroad electric powered touring cars. The E4RS promises to continue in the winning tradition of its predecessors and dominate the rubber racing arena. It comes armed and ready with the tools you need to get to the top step of the podium.
Unique Super Low Friction 3 Belt Transmission:
An 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!
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.
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.
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 fun doesn't stop there though because the E4 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 E4 chassis. From the wheels up, the E4 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 Shocks
New single O-ring shocks minimize drag for smoother more precise dampening.
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.
ST Stell Front & Alum. 7075 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.
Lightweight 34T Rear Pulley
Rear pulleys have been lightened with trapezoidal holes to reduce weight and friction of the diff balls. This results in faster acceleration and smoother differential action.
Now with Front Spool
Front and rear outdrives have been lightened as much as possible without sacrificing durability.
And Everything's About the Chassis
2.5mm carbon fiber bottom chassis, 2mm top chassis and 3mm front and rear shock towers mean that your chassis is rock solid to hold your setup consistently from the start of the race to the checkered flag. As a bonus it is compatible with most LiPo batteries.
No detail has been overlooked to put you on top of the podium. The choice is simple. Get an E4RS or follow one.
