The Xing-E Pro series is an economical version of the great iFlight Xing motors suitable for both freestyle and racing flying, with a very good price/performance ratio. They are durable, powerful, and affordable. This motor features a solid 4mm steel hollow shaft, larger NSK 9x4x4mm bearings, and high-quality bent N52SH magnets. The pro version comes in a unibell design. We recommend the 1800Kv variant for faster quads in combination with a 6S battery.
