3320 brushless motor for performance FPV multirotors Variant: 400KV, 4 pieces Product overview A durable 3320 brushless motor available in 690KV and 400KV options. This motor is built for voltage setups and heavylift multirotors, with a wide operating range and a design optimized for 8 to 10 inch propellers. The 400KV variant included in this listing provides efficient throttle response and improved lift for larger drones. Key benefits Wide voltage compatibility: Designed to run on 8S to 12S power systems for flexible integration into different builds. Proven propeller range: Optimized for 8 inch to 10 inch props to deliver strong lift and stable maneuverability. 400KV efficiency: Lower KV option improves torque and throttle control for heavylift and longrange applications. Lightweight construction: Reduces airframe weight to help extend flight duration and improve handling. Integrated cooling: Advanced cooling features help dissipate heat during extended flights and maintain consistent power delivery. Versatile compatibility: Suitable for performance FPV multirotors, XClass frames, and cinelifter setups. What makes it stand out Engineered for voltage, heavylift environments where torque and thermal management matter. Broad operating range lets builders use higher cell counts without compromising motor reliability. Propeller size focus balances lift capacity and responsiveness for cinematic and utility flights. Specifications and function Motor type: Brushless Model size: 3320 class KV options: 400KV and 690KV (this listing 400KV) Recommended prop size: 8 to 10 inches Recommended battery: 8S to 12S systems Quantity: 4 pieces per set Practical use scenarios Cinematic cinelifter: Paired with 8 to 10 inch props and an 8S to 12S power system to lift a stabilized camera rig for aerial filmmaking. XClass FPV craft: Use the 400KV motors on largeframe FPV builds for smoother throttle control and sustained hover with heavy payloads. Longrange or utility multirotor: Install on voltage setups that require efficient torque and reliable thermal performance for extended missions. note This listing contains four 3320 motors in the 400KV variant.
