This is the Team Orion Vortex VST 2, 8.5 Turn Pro Brushless Motor. Using the experience gained from the World Championship winning Vortex line of brushless motors, the Vortex VST2 Pro series is a completely unique motor design that features a convenient dual sensor port system that allows you to install the motor in the position that best protects the sensor wire. When combined with a Vortex ESC and program box, the unused port can then be used to program your ESC through the motor!

Additionally, the VST2 Pro features a redesigned sensor for outstanding performance and optimized efficiency. The case is a robust CAD design made out of high-grade aluminum machined at an extremely high level of accuracy and quality. Perfectly balanced rotors are used together with high quality stator materials. A sensor cable holder is included which at the same time protects the solder tabs!
