This is a 12x8 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.
"C2" design (see COMMENTS).
INCLUDES: One Carbon-Reinforced NYLON Propeller
REQUIRES: ALL props require balancing, this is VERY important
SPECS: Length: 12" Pitch: 8
Thickness at hub: 1/2" Hole diameter: 1/4"
