The Scorpion A2-10020 Brushless Outrunner Motor is part of Scorpion's flagship A2 Series, developed to provide the ultimate power system for giant-scale freestyle, aerobatic and UAV aircraft. Engineered using premium materials and advanced manufacturing techniques, the A2 Series delivers exceptional efficiency, reliability and power for the most demanding RC pilots.

Designed as an electric equivalent to a 120cc petrol engine, the A2-10020 produces up to 9,500 watts of peak power on a 12S LiPo system, making it ideal for giant-scale aerobatic models and UAV platforms requiring uncompromising performance.

The A2 Series achieves its outstanding efficiency through optimised high-strength rotor magnets, premium 0.2mm silicon steel stator laminations, and 200°C+ high-temperature enamel-coated copper windings. Combined with a robust mechanical design extensively tested by Scorpion's world-class team pilots, the result is a motor that delivers smooth power, excellent cooling and long-term durability.

Available in three KV ratings to suit your aircraft setup:

• 135KV – Ideal for maximum torque and larger propeller combinations.
  
• 160KV – Excellent all-round performance with outstanding efficiency.
  
• 175KV – Perfect for high-performance setups including 120cc equivalent aircraft
• using a 28×13 propeller on 12S LiPo.
