This is a 10.5x6 airplane propeller. It is a "tractor" (not a "pusher") prop.

FEATURES: Computer-optimized design gives these props a thinner profile and
            more "bite" with less noise.
          Lightweight molded nylon construction reduces rotating mass for
            higher output and longer life.
          Reinforcing carbon fibers help maintain true, constant pitch at
            any rpm.
          "C3" design (see COMMENTS).

INCLUDES: One carbon-reinforced NYLON propeller

REQUIRES: ALL props require balancing, this is VERY important, use TOPQ5700.
          May need prop reamer, use GPMQ5005 (SAE) or GPMQ5007 (Metric)

SPECS:    Length:  10.5     Pitch:  6

COMMENTS: "C3" number identifies the specific lot when the prop was made.
