Constructed of glass filled nylon for strength and durability
11x6 3-Blade Glass Filled Nylon Propeller
When using 3-blade propellers, avoid high RPM aerobatic manuevers
such as snap-rolls.
The general rule when replacing a 2 blade prop with a 3 blade is
subtract 1" from diameter and increase pitch by 1" if possible.
Adjust to 2" for larger diameters 14" and up.
