33151B FO-XX GP w/KT-231P 1/8 GP 4WD RS


Go ballistic with rigid axle 4WD + 3-speed A/T + 25-class engine power!

From its crawler-like agility to explosive power for wheelie starts, the FO-XX GP takes monster trucking to a new level. Formula off-road form combines with paddle tread pattern tires to produce breathtaking running performance. The hybrid tube frame and monocoque chassis structure is adorned with a pre-colored body and dummy front fog lights to create an intrepid style. A hinged front opening allows for fast and easy maintenance while the inner cover inside the fender not only fills the gap between the tires and chassis for improved scale appearance, but also keeps dirt out from the chassis. Proud owners of the FO-XX GP will be impressed with the fine attention to detail throughout, not to mentioned the proven front-rear 3-speed transmission + rigid axle + chain & shaft driven 4WD from the Kyosho Mad Force. Equipped with new polished welded manifold, tuned muffler and KE25 engine as its power source, the FO-XX GP becomes an unstoppable force. Use the break-in reducer and there is no need for break-in adjustment so even beginners can enjoy the brute force of the FO-XX GP as its runs wheelie charges with its powerful acceleration. This is a fully pre-assembled Readyset so all that's required is the fuel, engine starting tools, and batteries for the R/C system. With the 2.4GHz Syncro KT-231P transmitter included, simply switch the power on and it automatically scans for an open frequency to use. Other features include separate dual-rate settings and a failsafe function that applies full brakes if the signal is lost. Combining real machine form and unstoppable running power, the FO-XX takes off-road to the extreme.
