E-flite’s latest Park 370 is a brushless outrunner motor that features a 4mm hollow shaft, ideal for use with variable pitch propellers. It’s perfectly designed for electric models equipped with variable-pitch propeller systems, such as the E-flite® ShowStopper VPP system. However, you don’t need a VPP to use this motor—it’s an excellent motor for small 3D airplanes that weigh 7–14 ounces. A motor mount, prop adapter and all hardware are included.
