Team Magic E4JR – Ready to Run Racer!
The new E4JR electric touring car chassis from Team Magic is a 95% pre-built, ready-to-run electric touring car which focuses on price and performance. No longer can you consider a chassis manufactured from plastic instead of carbon fiber, a low spec product when it features high quality components and features like those found on the new E4JR.
From its intricate, but highly efficient transmission, to its state of the art suspension geometry; the E4JR has close to everything a racer will ever need in just one box. The overall design of the car follows on from the already successful E4 series so there’s no need to be concerned about its ability to perform.
Let’s take a closer look at what the E4JR has to offer:
95% Factory Pre-Built
The E4JR is 95% factory assembled for your convenience. The remaining 5% needed to get your car up and running is incredibly simple. No wires or soldering, just choose your favorite color for the pre-styled Mazda6 body shell, obtain some batteries for the transmitter and after a quick charge of your H.A.R.D. NiMh battery pack your ready to go!
The whole car is carefully factory assembled saving you a considerable amount of construction time so you’re up and racing as quickly as possible.
The E4JR 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 E4JR surrounded in high quality but low cost plastic, savings are then passed onto the end-user.
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 E4JR 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 belts and these items are already included as standard on the E4JR.
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.
Many of the parts found on the E4JR 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.
Although we high recommend the E4JR 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.
With these options available for the E4JR, the car is capable of running on any surface and any track.
Electronic Speed Controller and H.A.R.D Motor
The main electronic components inside the E4JR are the H.A.R.D. JR Dual Mode Electronic Speed Controller and H.A.R.D. super quick motor. The high quality, super efficient Electronic Speed Controller (ESC) is designed to offer you total control of your cars speed and braking performance.
Programmed and setup ready to go from the factory, the H.A.R.D. JR ESC offers a dual mode function as well as reverse. The dual mode feature is ideal for a beginner who wishes to learn how the car steers and drives at slower speeds. Press the button for 3 seconds and the Dual Mode ESC drops into “Gentle Mode” for easy acceleration and control.
However, once you’ve mastered the cars handling, push the button again, and the Dual Mode ESC jumps into “Fierce Mode”, unleashing the true potential of your H.A.R.D. 18 Turn motor! Acceleration is improved dramatically for some serious fun.
The H.A.R.D 18 turn motor is incredibly powerful and is much faster than equivalent kit motors. It features internal cooling fins for improved performance and durability. And the best thing of all… the motor is completely maintenance free!
H.A.R.D. Radio System
Designed and manufactured by Futaba, a leader in radio transmitters for more than 40 years, the kit transmitter and receiver units are guaranteed to be of the highest quality available. From its lightweight design to its ergonomically designed handle, the H.A.R.D. Radio System is a perfect match for the E4JR and will offer years of untroubled service.
Narrow, Low Center of Gravity Chassis
Molded completely from high quality plastics, the bath tub chassis of the E4JR is the back-bone of the entire car. It’s responsible for holding every other component in its place and must remain strong and rigid even in the biggest of crashes.
The super narrow design means that weight savings can be accomplished without sacrificing durability. In addition to this, all the components fitted or attached to the chassis sit incredibly low to the ground for a center of gravity even some of the top-of-the-line chassis would envy. All of these characteristics add up to a chassis which is now accepted as one of the quickest cornering R/C cars in the world.
Tires and Wheels
As with any RTR kit, the chassis requires wheels and tires to get it working. Fortunately, the tires, wheels and inserts included with the E4JR aren’t some low-cost, low grip hard rubber compound tire.
The pre-glued tires on the E4JR are as close to competition level as you can get. They offer substantial amounts of grip without the hassle of gluing. A perfect match for the powerful 18turn H.A.R.D motor!
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 E4JR has got to be one of the best cars on the market to drive fast.
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.
Also included is a high quality set of alloy/plastic shocks. 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.
The E4J R offers a heap of tuning options via K-Factory’s optional parts list.
Everything that you’d need to turn the E4JR into a top-of-the-line competition racer is available from K-Factory. Adjustments like camber, toe and roll-center are possible thanks to readily available hop-up parts. The list is huge, but to say that anything and everything to alter the cars handling is available the E4JR 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.
A notable difference between the other E4 chassis’ and the E4JR 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. Two thumb screws hold the battery in place without any need for Velcro or tape.
Thanks to the new chassis design, the E4JR is right at home with hard cased LIPO battery packs too. If you’re considering obtaining a second battery for your car, the options are endless.
The new Team Magic E4JR is the ultimate RTR electric touring car package available. Thanks to its super quick 18 turn motor and its high quality components, the E4JR is state of the art engineering at its best. Add to that, strength and dual mode acceleration and you’ve found a perfect match for any driving ability. The fun can start today!
