Kimihiko Yano and Team CRC Japan are pride to introduce the Team CRC Gen-X JSPEC.

This car was developed by Kimihiko Yano, Team CRC Japan and in cooperation with Team CRC in the USA. Kimihiko Yano and Team CRC Japan get the car late July and they just start some testing this prototype. The car presented here is not the final version, those specifications are temporaries and may change during testing to define the best compromise.

The main Kimihiko Yano and Team CRC Japan's aim is to optimize the original car on asphalt track, main racing surface in Japan.

This chassis will not necessarily put on the market from CRC.

Development concept

Rear traction rise
Chassis is softer than the standard car, in all road surfaces soft correspondence
Front and rear adjustment of ABP
Degree of freedom rise due to change in center shock mounting angle

While the corner incising sharply, the corner ring which is the sense of security with good rear traction, the corner exit is faster with this increase of rear traction!!

Difference with the standard generation X:

- Chassis thickness is 2.21mm
- Rear pivot ball moves  3 rear
- Wheelbase extended for 3mm
- Front and rear battery position:
     Battery can be moved backward form about 5mm
- Antenna post position relatively to the rear pivot ball
     Antenna post move head from about 6mm. Pod top pate modified as appropriate
     Center shock pivot position moves forward
- Side link extension position can be adjusted with an additional hole located 10mm forward, to reduce the effect of the pod motion and steering effect in curve
- Servo moved closer to the front end

* F tread normal is the same.
* Tweak Plate uses normal.

Gen-X JSPEC

Damper installation position on the upper plate moves to the front from normal. as consequence, degree of freedom of pitching damper angle improves.

The servo hole even with KO servo has become the right on-board possible hole, you use the servo mount of new model and the front hole  will be used for JR servo, as for KO servo, the rear hole will be used, the servo axis must be maintained the same position. This modification is done to gain some space for a Brushless ESC.

More details about of Gen-X JSPEC prototype.

Testing report

Total testing days: 3 @ Raji Heaven, Nagoya. As it can be seen on pictures, this is an indoor track quite wide, close to what you can get in the Yatabe arena. This is an asphalt track so with moderate grip but  constant during all testing sessions, which is nice.

Still, 3 days and it is short test period, but because quality and the problematical point etc on the prototype we introduce, it announces in a way, interim report.

First, a standard Gen-X was running to get some comparison.

Also completely another car about feels, had become the car where quality is different. Concretely, when pulling out the throttle with entering a corner, in order to load the front tire at a stroke, you were confused to the hypersensitive movement. Due to sufficient rear grip, if you are used to, running fast is possible but control is very difficult and the running constantly was not possible.

When one cause of this hypersensitive movement after that was ascertained with the test and added improvement it was settled and send became easy.

It was the plate where as for the problematical point quality of the plate is inferior to durability and is easy to exfoliate. In this car which does not have a T bar, fading of the top plate and the rear bottom plate of the especially important part is quick, marketing with the this way plate in everyone of the user becomes also burden that and, efficiency cannot be maintained in long life, it judged, order did the revised edition of latest prototype at the CRC corporation.

In each case it announces the concrete improvement point, but until agreement goes, thinking, that you repeat improvement, would like to keep to make good ones it increases. It catches already for a while to sale, but, it does not sell the kind of car which betrays the expectation of everyone. To completion waiting in the pleasure.

This time, ESC was changed on another JSPEC prototype.

Up-to-date ESC of Advanced Electronics 5.1is used here. It received the request for the test in March 2007, and compared with other up-to-date ESC while it tested.

This ESC is highly suitable for 1:12 scale car as it is small size and lightweight, the ESC switch is built in by the substance, will be also the cords clear and the packaging and the like likes and increases. Also efficiency and feeling are essential to an ESC were my taste. As for feeling and the powerful impression of reacting to linear in punch and throttle operation in the low-speed limits there is no something to say, is.

But, when the powerfull motor is used, ESC generate heat  and that's became a matter of concern . When the case is conveyed to the Advanced Electronics Corporation the marketing version which used up-to-date FET being sent, when it tries testing promptly, you could hold down heat generation beautifully, without problem completely you could use even at this hot time. Also efficiency rise was done and by up-to-date FET also fuel economy became good.

Because the high performance of this ESC, not only 1/12, you show excellent efficiency even with other category that you think whether with drive frequency modification.

The report is ending here.
The Yatabe Arena will host the Japan Championship meeting soon and we will see what will be the result there

Many thanks to Kimihiko Yano and Team CRC Japan!
