T-Motor AM5K 330 KV2800 Brushless Motor

Heavy-Duty Propulsion for Competitive Soaring

The T-Hobby AM5K 330 is a powerhouse brushless motor engineered specifically for demanding F5K and F5L competitive gliders. If your glider falls within the 1.2m to 2.0m wingspan range or carries a heavier 300g to 600g take-off weight (AUW), the AM5K 330 offers the incredible torque and instantaneous burst power needed to push your aircraft higher and faster.

Unleash Efficiency & Raw Power

Featuring an optimized 12N14P configuration, the AM5K 330 brings a 20% system efficiency boost alongside a 5% peak thrust enhancement to your setup. Whether you need the smooth endurance of the 2450KV model or the blistering 604g climb rate of the 2800KV variant, this motor ensures your prop unfolds instantly and performs flawlessly when every second counts.

• High-Power F5K & F5L Performance: Specifically tailored for 1.2m to 2.0m competition and sport RC gliders, providing massive thrust to conquer aggressive launch angles and rapidly catch thermals.

• Dual KV Options for Precise Tuning: Choose between 2450KV (optimized for higher efficiency and multi-S setups) and 2800KV (tailored for explosive raw power and rapid altitude gains).

• Massive Power-to-Weight Ratio: Weighing only 19.7g, it unleases up to 239W of maximum power and 604g of peak thrust, giving heavier or windy-condition gliders an undeniable edge.

• Advanced Thermal & High-Voltage Resilience: Built with 200°C high-temperature resistant magnets and upgraded to a 500V withstand voltage coil insulation test to handle intense, back-to-back contest heats.

• Vibration-Free Kinetic Balance: Strictly balanced to standard requirements of ≤4mg. Minimizes airframe resonance, preserves energy efficiency, and ensures buttery-smooth throttle transitions.
