Final price reduction. This is a set including a motor, a 60A ESC, a spinner, and a 13x6 propeller, all used on a 50-class airplane (1400mm wingspan 3D plane). An unused 13x6 propeller is also included. The motor size is about 40x40mm, and the KV is 720. I used it with a 4-cell battery, and it had good pull and flew powerfully. Shipping will be via Letter Pack Plus. Free shipping. Thank you.
