  • The AX-18A has a bigger Stall Torque than the AX-12A. So if you want to boost your performance replace all AX-12A or simply just those at the joints with a too small torque by the AX-18A.
  • Contains No. 4 metal gear to enhance endurance
  • For safe usage maintain the highest limit temperature at the default value








CAUTION: No Accessories(e.g. cable, bolts,...) included

Frame Purchase Guide

  • The old horns are only compatible with the old frames and the new horns are only compatible with the new frames.
  • If you are using the OLD horns, you MUST purchase the OLD frames. If you are using the NEW horns, you MUST purchase the NEW frames.
  • If you are using OLD horns, but want to use new frames, you MUST use both NEW horns and NEW frames.

EXAMPLE: If you are using the RX-64 HN05-N1 Set(Horn Rx-64), you must purchase the RX-64 FR05-H1 Set(OF-RX64H Set).
