Adopting a composite chassis combining a narrow type lower deck with an upper frame, the drive system is single belt 4WD. In addition, the TA07 PRO touring car chassis supports three different motor layouts and various course layouts and settings. This chassis is packed with optional parts carefully selected by TRF members, and the TA07RR is designed to win the race. Dedicated carbon front stiffener improves pitching rigidity while maintaining roll flexibility. It improves the grip on the front and creates stable cornering performance. In addition, the drive system has a double cardan drive shaft, TRF420 front axle, aluminum center pulley, etc. to improve efficiency. The suspension can be set more delicately with the TRF419 suspension upgrade set and aluminum adjustable suspension mount. A dedicated servo mount and front and rear soft type stabilizer are also set.
