The invention relates to the technical field of unmanned helicopters, and discloses a tail rotor transmission system and an unmanned helicopter. The tail rotor wing transmission system comprises a rack, and a tail mechanism which comprises a tail rotor assembly, wherein the tail mechanism is rotationally connected with the rack, and the tail mechanism can rotate upwards relative to the rack to bein a bent state and can also rotate downwards relative to the rack to be in an unfolded state; the tail rotor wing transmission system further comprises a main shaft which is installed on the rack andused for being connected with a main rotor, and a transmission belt mechanism which comprises a driving belt wheel, a driven belt wheel and a synchronous belt; the synchronous belt is tensioned on the driving belt wheel and the driven belt wheel, the driving belt wheel is in transmission connection with the main shaft, and the driven belt wheel is in transmission connection with the tail rotor assembly. The tail rotor transmission system provided by the invention not only can be folded and is convenient to transport, but also the synchronous belt is convenient to disassemble and assemble.
