KYO30637 Kyosho 1/12 Fantom EP 4WD CRC-II Kit
Amazing running agility! "FANTOM EP-4WD Ext" is the last reincarnation of the famous FANTOM EP form!
Two years after the seismic impact of the FANTOM EP-4WD’s debut win, the "FANTOM EP-4WD Ext" stunned the world by achieving the same feat against an even more competitive field at the 1985 Japan Championship. Racing surface conditions at that time were improving and race formats changed from the fiery 4-minute races to 8-minute endurance races. The "FANTOM EP-4WD Ext" was developed to meet this trend. Kyosho was the first to introduce the chain + one-way 4WD system developed for 1/8 engine models into 1/12 electric racing cars. The front one-way system enabled power to be applied earlier through corners, allowing for more aggressive driving. On the other hand, energy efficiency didn’t improve and it was prone to stalling when power was taken off. In the Ext, high-dimensional fusion of the 3P suspension reinforces weak points. 2.2mm suspension stroke is realized through specially shaped springs creating a "progressive spring effect" by compressing the suspension according to the roll amount of the chassis when entering a corner, and then extending from when it starts clipping too much to minimize stall when power is taken off. At the same time, energy efficiency is improved by reducing the time power is ON. The main chassis has been enhanced with an evolved front suspension to deliver increased rigidity from a reinforcing plate on the front that allows optimal movement of the suspension. Incorporating the direct servo saver into the steering servo increases the front load, allowing the chassis to be shaped so that the rear rolls and pitches flexibly in sync with the front. Oil damper is added for pitching control to improve the ground contact of the rear. When first developed, the Ext was focused on weight reduction and its 880g was lighter than the first generation. The commitment to light weight remains in this relaunched version with the inclusion of lightweight knuckle arms and wheel nuts. Please enjoy this modernized version of Kyosho’s timeless classic, the "FANTOM EP-4WD Ext", which is the 11th model in the vintage series.
The FANTOM was the first electric R/C car in the world to adopt the ladder chain + front one-way bearing drive system, and in combination with an integrated 3P suspension system, delivered superior cornering speed and driving agility.
The CRC-2 body and its reputation for excellent aerodynamic performance has been faithfully reproduced. The long front overhang and full-body wedge produces handling stability with minimal aerodynamic variation due to speed. Includes decals to recreate the model on the package.
Special spring produces a progressive suspension effect that changes according to the amount of roll and ensures suspension stroke, even in a small space. New front sprocket, special swing shaft (right only) and lightweight knuckle arm, deliver maximum steering angle.Compatible with optional carbon suspension arm (No.EFW005).
Chassis is shaped to deliver rear suspension effect. Newly designed oil damper is equipped along the pitch direction and features a 2mm shaft to minimize changes in oil volume during stroke and ensure sufficient damping effect. High-precision CNC machined 3-piece motor mount and damper stay with oil damper produce reliable operation.
Moving the height adjuster in the rear axle up, down, left and right, allows the vehicle height to be changed 1.3 mm and the wheelbase to be changed by 1 mm (also adjusting the chain tension). Originally an optional setting, the motor mounting position is lowered to the same position as the machine-cut motor mount to produce a lower center of gravity.
A new long-type 48 pitch 21T pinion gear with newly designed differential is fully equipped with ball bearings to realize smooth operation. Optional 16T to 27T pinion gears are also available for a wide range of settings. Compatible with No.PNGS4816-4827 / No.W0118Z-W0119Z Lightweight Carbon Gear Differential Axle (No. EFW002).
CNC processing improves the precision of all FRP parts that were originally press-processed. The 2-piece main chassis is equipped with mounting holes for the Le Mans 240S speed controller. The newly designed CNC machined aluminum servo mount is compatible with most mini servos for cars and incorporates a newly designed direct servo saver with double ring springs to ensure durability and accuracy.
Full bearing specifications. Hex screws throughout ensure greater integrity of screw tightness. Includes wrench for wheel hub and differential adjustment. (12 / 5.5 / 4.5 / 4mm) Special damper wrench is also included.
Includes pre-formed and glued tires that do not require a tire setter. Front: φ48 / H38 ° Rear: φ53 / L25 ° Lightweight wheel nuts are used. Optional small diameter tires (pre-formed and glued tires / H = 38φ45mm / L = 25φ50mm) (No. EFTH 100W) are available.
