Description

Speedmaster Stinger Strut

It can be quickly adjusted from positive to negative thrust angles. The bushing is cross-drilled to hold grease for an extra smooth driveline. It is constructed from high-quality aluminum and CNC-machined to tight tolerances. This has often been copied by other manufacturers but has never truly been duplicated.

– SPDSD-2140: Electric/Nitro for 3/16″ (.187″) propeller shafts.
– SPDSD-6090: Nitro, for 1/4″ (.250″) propeller shaft.
