5.0X2.75 carbon tow reinforced resin propeller. This batch of KT12s is green, but the pitch and diameter is the same as the previous batches that were clear resin.
KIT TIP: The bolt hole in KT propellers is larger than prop bolt on TeeDees, Norvels, and VAs. A suitable shim can be made by slipping a 3/16" long piece of KT20 latex tubing over the bolt. As a bonus the tubing also helps keep the bolt from coming out of the spinner when you change props.
