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 with high quality aluminum and CNC cut to tight tolerances. This has been often copied by other manufactures but never truly has been duplicated.

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