Original price was: $53.90.Current price is: $20.00.

High-performance industrial-grade D3115 900KV brushless motor, engineered for heavy-lift FPV cinelifter, mini VTOL fixed-wing, and small agricultural crop duster drones. Weighing only 112g, it delivers a 4.2KG peak static thrust and 1652W max power, with 3S-6S wide voltage compatibility, factory-calibrated dynamic balancing, and a universal 19x19mm mounting pattern for drop-in fit on most mainstream drone frames.

Description

Key Features & Performance Highlights

  • Industry-Leading Power-to-Weight Ratio: Weighing only 112g while delivering a 4.2KG peak static thrust and 1652W max continuous power, this 900KV 3115 drone motor achieves an unmatched balance of lightweight design and heavy-lift performance for 9-10 inch FPV, VTOL, and compact agricultural drone builds.
  • Smooth, Stable Power Delivery: Built with a 12N14P slot pole configuration and factory-calibrated dynamic balancing on every unit, it delivers near-zero vibration across the entire throttle range, eliminating jello effect in aerial footage and ensuring stable flight for professional cinematography, mapping, and precision spraying.
  • Reliable Thermal & Electrical Performance: With a 48mΩ optimized internal resistance and 90% peak working efficiency, it minimizes power loss and heat generation during sustained heavy-load operation. It is fully compatible with 3S-6S Lipo batteries, paired with a recommended 6S / 80A ESC for safe, consistent full-throttle performance.
  • Heavy-Duty Durability: Reinforced heavy-load design with a robust 6061 aluminum shell, M5 stainless steel spindle, and customizable water & dust protection, making it crash-resistant and suitable for harsh outdoor farming, surveying, and FPV flight environments.
  • Universal Drop-In Fit: Standard 19*19mm 4-M3 motor mounting pattern and 250mm pre-tinned motor cables, compatible with 90% of mainstream 9-10 inch FPV cinelifter, mini VTOL, and compact agricultural drone frames, with no extra modification required for fast assembly.
