This is a 8x7 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.
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 (Metric)
SPECS: Length: 8" Pitch: 7
