The 6010 Standard and Pro motor bearings are fully sealed to prevent fluids like rain, pesticide, and salt spray from entering and causing corrosion. A special surface coating applied to the stator also greatly improves its ability to withstand rusting.
The same effective weather sealing has also been applied to the external 1240S ESC found with the E2000 Standard.
*The E2000 Standard has an IP56 rating.
