PR SB401-R 1/10 Electric 4wd Off Road Buggy Kit

PR racing have been hard at work developing the next generation of the successful SB401 platform and have made the SB401-R faster, quieter and easier to maintain and tune.

A number of key components have been totally redesigned to produce a better handling and more forgiving car to drive. The main focus has been on the all new narrow 2mm 7075-T6 chassis and plastic side-pods, which utilizes a carbon fibre re-enforced spine to control torsional and longitudinal flex. The additional flex has proved to increase grip, and make the car feel more balanced and easier to drive leading to faster, more consistent laps.
