Ground adjustable variable pitch prop for scale airplanes. Choose the size (9-1/2" or
10-7/8" diameter) that is appropriate for your airplane. Each prop has a pitch range from 5" to
15". In it stock form, a pitch of 10" is automatically set without the need of a pitch gauge. To set
other pitches, each prop includes a wooden pitch gauge. A tab must be removed from the base
of each prop blade to change the pitch to a setting other than 10". Each prop set includes the
pre-painted set of blades, a set of decals for you to install, a scale chrome-plated plastic hub and
spinner (the 2-blade prop does not have a spinner - it's hub represents an early scale version of
a constant-speed prop), and prop retention screws. All that is required is the purchase of a prop
adapter for your application. Adapters for 3, 3.2, 4, and 5mm are available separately.
