Gear design was changed to improve durability. Therefore the AX-12A Gear Set (SKU No. 902-0087-001) is not compatible with former AX-12+ Gear Set (SKU No. 903-0087-000).



AX-12A is a new version of the AX-12+ with the same performance but a more advanced external design. It is 100% compatible with the AX-12+, has the same dimensions and uses the same control method.








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.
