This is a 14x6 airplane propeller. It is a "pusher" prop (see comments).
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.
One carbon-reinforced NYLON pusher propeller
ALL props require balancing, this is VERY important
May need prop reamer
Length: 14" Pitch: 6
