XNOVA LIGHTNING 4025-1120KV 1.5Y V3 – Shaft A
The XNOVA LIGHTNING 4025-1120KV is a high-performance brushless outrunner designed for powerful 6S setups in 520–600 class RC helicopters. What sets Xnova apart is not only its strong peak power, but also its efficiency and highly consistent power delivery throughout the flight. The LIGHTNING V3 series is engineered to run cooler and reduce efficiency losses as motor temperature rises, helping maintain a more stable power feel from the beginning of the flight to the end.
This becomes especially noticeable during demanding 3D flying and in hot summer conditions, where less efficient motors can build more heat and gradually lose some of their punch as the flight continues. Xnova’s low-cogging design, optimized stator construction and high-temperature components help keep performance smooth, predictable and consistent even under sustained load.
The Shaft A version features a 6mm × 36mm shaft and is an excellent fit for helicopters such as the OMP M5 and Goosky RS5. With up to 3000W continuous power and 4000W peak output, it is well suited for demanding sport and aggressive 3D flying.
