About 4WD CHASSIS
Motor: RA-130 Speeds: Forward and reverse
Chassis: Pre-cut wood
Capable of negotiating rough terrain, the 4WD Chassis incorporates a four-wheel shaft-drive system similar to those in full size 4WD vehicles. A hex shaft transfers power from the center gear box to the outer gear box giving 4WD power. The semi-pneumatic tires enhance traction, the roll bar also prevents damage in rollover incidents.
