Fpv Motor Summary

The Tracker 3115 Brushless Motor is a high-performance powerplant designed for FPV pilots building 9–11 inch racing and long-range drones. With dual KV options, premium materials including Kawasaki silicon steel stator, NMB bearings, N52H magnets, and a lightweight titanium alloy hollow shaft, this motor delivers reliable thrust, efficient power delivery, and exceptional durability. Whether racing at high speeds or cruising long distances, the Tracker 3115 provides the performance required for demanding FPV applications.

Tracker 3115 – Aerospace‑Grade Power for 9–11″ Long‑Range & Heavy‑Lift Fpv Motor

When you need to swing large 9–11″ propellers with confidence, the Tracker 3115 delivers unmatched torque and durability. Engineered from premium materials and featuring a unique titanium alloy hollow shaft, this motor is built for endurance, heavy payloads, and demanding long‑range missions.

Key advantages:

• Optimized for 9–11″ props – Perfect for large long‑range cruisers, cinema rigs, X‑class racers, and industrial survey drones.
• Two KV options, one platform
  – 640KV – Ideal for 6‑8S setups with 10–11″ props (max efficiency & flight time)
  – 900KV – Great for 5‑6S builds with 9–10″ props (more responsive, spirited flying)
• Titanium alloy hollow shaft – Ultra‑strong, lightweight, and corrosion‑resistant. Hollow design reduces rotating mass for quicker throttle response while maintaining crash resilience.
• Aerospace 7075 aluminum – Both bell cap and base casing are CNC‑machined from 7075 alloy, offering superior strength and thermal conductivity over standard 6061.
• 0.2mm Kawasaki silicon steel stator – Low eddy current losses keep efficiency high and temperatures low during sustained climbs or heavy payloads.
• N52H arc magnets – Highest grade neodymium magnets provide maximum torque density without increasing motor size.
• Oversized Japanese NMB bearings (11x5x5mm) – Greater load capacity ensures smooth operation and long life under high thrust.
• Standard 19×19mm M3 mounting – Compatible with all full‑size frames (Mark4, Apex, LR, and XL frames).
• M5 prop shaft thread – Industry standard for 9–11″ props, compatible with carbon, folding, and multi‑blade propellers.
• Robust electrical design – 12N14P topology, 18AWG 250mm silicone leads, and 110g weight (with wires) for an excellent power‑to‑weight ratio.

Recommended pairings:

• ESC: 50A–70A (BLS 60A/80A/100A recommended for 640KV on 8S)
• Flight controllers: F4, F7, SpeedyBee F405/F722, KK
• Propellers: 9″, 10″, or 11″ depending on KV and battery

Whether you’re flying a 10″ long‑range quad loaded with Li‑ion packs or building a heavy‑lift cinema drone, the Tracker 3115 delivers the torque, thermal headroom, and build quality to go the distance.
