Tamiya Racing Factory (TRF) has won the 2002, 2004, 2008, and 2010 IFMAR ISTC class World Championships. With an eye on winning the next IFMAR ISTC Class World Championship in 2012, TRF has introduced the newly developed TRF417. Based on their championship-winning knowledge and feedback, the TRF417 features an optimized chassis layout to meet the latest regulations which call for rectangular-shaped batteries, brushless motors, and control tires. New developments include greater motor mount rigidity, a different motor position, improved secondary gear reduction, redesigned steering linkage, and large capacity ball differentials. Front and rear bulkheads are identical and the suspension is coupled with proven parts such as short reversible suspension arms and uprights with 1050 ball bearings, which all help improve the machine's high-traction cornering characteristics.
