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.
