The key feature of this chassis is the innovative transmission system which employs two equal-length drive belts mounted front and rear, interlocking with tooth surfaced center pulley. This design greatly reduces drive resistance to achieve better transmission efficiency at high speeds. The chassis structure has been redesigned for optimum balance, locating the motor in center-left and battery in center-right position. Center shaft, drive belts and spur gear have also been repositioned for improved balance. Suspension is the same durable and reliable system found on the TA04 chassis. Several features make this chassis wonderfully easy to perform maintenance on, such as the single deck frame and one-piece motor mount. Front and rear bulkheads are identical and feature 2-piece detachable design. New-style mount allows diff to be removed without detaching stabilizers.
