The Emax brushless motors are at the forefront of technology with the unique use of glass reinforced plastics in the construction of the casing. This produces an ultra-light weight motor that still retains strength and durability. Combine this with high grade bearings and magnets as well as reliable metal stator brace and mounts.

Each set includes both clockwise and counter clockwise threaded prop adapters， making these a must for the 250 size multi-rotors. 

Features:
• Glass reinforced plastic casing
• Lightweight and robust
• High quality bearings
• High quality magnets
• CW and CCW threaded prop adapters
• Metal inserts for mounting
