3-Blade Propellers
The 3-Blade Series is ideal for a scale look and/or when ground clearance with a 2-blade difficult. This series has a range of 6" up through 16" diameter. We have add a few "pusher" or "counter-rotating" sizes as well. The 3-Blade Series is made of black-glass-filled nylon for strength and durability. When converting from 2-blades to 3 blades, reduce your diameter and either stay at or increase pitch.
