With the Team Magic E4RS III’s competitive success (multiple national champion, ETS finalist etc.) and the E4JS II’s huge commercial success, which has become the "car of the year 2014" in numerous clubs, we decided to offer to the largest possible public the opportunity to drive the E4 "II" series’ high-performance chassis by offering three Ready-To-Run versions (RTR) and one Ready-To-Build version (RTB).

For this, we worked hard on the E4JS II in order to reduce it in an optimized RTR version. We created a new part that transforms the front differential into a spool (rigid axle), new battery mounts that allow the use of batteries with rounded shape (NiMH or LiPo) and simplified a number of parts in order to maintain an ultra-competitive price (lower chassis, shock mounts and motor mount), all this supplied with waterproof electronics (servo, receiver and speed controller!).

The result is the E4JR II, the most competitive and innovative RTR car on the market!

The features inherited from the E4RS III:

Team Magic utilised numerous elements and parts of the E4RS III to create the E4JS II, which is so in no way a touring car of reduced quality.

The features inherited from the E4JS II:

The E4JS II is "THE" club racer car reference (a club racer is a confirmed driver est un pilote confirmé, demanding a high quality level, but which wants to keep a reasonable budget and to limit himself to regional championships).

Team Magic E4JR II new features:

Suspension geometry of the E4RS III:

As with the E4JS II, the E4JR II uses the same suspension geometry developed for the E4RS III.

Furthermore, the E4JR II’s arms, c-hubs and uprights are all directly from the E4RS III to guarantee a high level of handling and quality.

Centred and aligned weight distribution:

The E4JR II’s weight centring and distribution is almost identical to that of the E4RS III.

The E4JR II benefits from the same overall balance as that of the E4RS III, which has more than proven itself in competition.

Narrow 2.3mm ECO-Graphite chassis:

The E4JR II’s chassis uses the famous "ECO Graphite" material that was specially developed for the E4JS II.

This material is one of key of the successes of the E4JS II; because it brings forward an excellent handling due to a flex particularly that is well adapted to many surfaces and grip levels found in the majority of clubs.

3.0mm ECO-Graphite shock towers:

As the chassis and the upper deck, the 3.0mm shocks towers are machined in ECO-Graphite.

To facilitate the setup of the E4JR II, and to improve these parts’ durability, we have slightly simplified the number of possible position of the shock absorbers.

Matched and optimized shock springs:

The shock springs also come from the E4JS II. They are matched and optimized for standard use in 1/10 Touring Cars.

The front springs are standard springs with 6.4 coils of a 1.5mm thickness, which offer a good front end control. These are accompanied by rear springs with 6.2 coils of 1.4mm thickness which provides a good progressivity and softness for the rear end.

This choice of springs provides a good balance to the car and a good handling on tracks with a medium level of grip.

Belt tension eccentric adjusters:

Team Magic chose to colour their belt tension eccentric (origin E4RS III) adjusters in orange; not to look pretty, but to stand out visually in the black bulkheads and allow users to easily check which tension notch the eccentric positioned with a quick glance.

Orange being the basic colour of the Team Magic logo, the colour perfectly contrasts with black.

Gear differential with composite gears:

As we do with the E4JS II, the E4JR II is equipped with the E4RS III gear differential with 4 moulded composite satellite gears.

This ultra-compact differential is very light and efficient.

The double gasket system ensures the differential is perfectly sealed. The diff case is moulded with four unclosed screw holes *WPV in order to avoid any negative pressure under them for a greater durability of the screw thread in the main differential case.

Front rigid axle (spool):

To facilitate the driving of the E4JR II, Team Magic chose to equip its car with a front rigid axle (also called spool).

For this, we simply created a central block replacing the internal gears of the differential, to prevent any movement.

It is completely possible to transform this rigid axle into a differential, for this simply replace the block with a set of differential gears (TM507206).

Steel differential outdrives:

The E4JR II uses the same differential outdrives as the E4JS II and are machined in steel in order to ensure an extreme durability.

These outdrives also perfectly complement the use of the E4JR II’s universal driveshafts.

Back on the top of page


Steel differential outdrives

Universal driveshafts:

The universal driveshafts come directly from the E4JS II.

These simplified driveshafts features a retainer clip for the articulation pin, instead of the usual grub screw.

We chose to use simple universal driveshafts, provided with a big 3mm pin instead of the traditional blades of the E4RS III, because the user has be able to drive without having to care of the state of their blades.
