2306 stator size generates 20% more torque than predecessors, with ultra-low ripple current for buttery-smooth throttle response. Balanced magnets eliminate vibrations even at 35,000 RPM—perfect for freestyle flips and precision cornering. 

Hollow-core shaft + aviation-grade alloy housing dissipate heat 40% faster. Tested for 50+ consecutive flights without power drop—ideal for intense racing sessions in tropical climates.

T-HOBBY F40 PRO IV 2306 Buying Guide

The T-HOBBY F40 PRO IV is a 2306 motor designed for 5-inch FPV freestyle and racing. Its lightweight construction, high torque, and responsive power delivery make it a good choice for pilots who want precise throttle control and quick response without adding unnecessary motor weight.

Choose the Right KV

KVRecommended BatteryBest For
1950KV4S–6S5" freestyle and all-round flying
2400KV4SFaster response and aggressive 4S flying

For a typical 6S 5-inch freestyle build, the 1950KV version is the more suitable choice. If you prefer 4S and want a higher-RPM setup, the 2400KV version provides a faster motor response.

F40 PRO IV vs MEPS SZ2306 V2

Both motors use a 2306 stator and are designed around 5-inch FPV drones, but they target slightly different priorities. The F40 PRO IV focuses more on lightweight construction and precise freestyle/racing response, while the SZ2306 V2 offers more KV choices and a more value-oriented setup for everyday freestyle flying.

Which One Should You Choose?

Choose the F40 PRO IV if you are building a performance-focused 5-inch freestyle or racing quad and want a lightweight 2306 motor with a more premium design and precise response. The 1950KV version is the natural choice for 6S.

Choose the MEPS SZ2306 V2 if you want a more flexible and cost-effective 2306 motor. Its 1750KV, 1950KV, and 2450KV options cover a wider range of 5-inch 4S and 6S builds, making it easier to match the motor to different flying styles.

Quick choice: F40 PRO IV for a more performance-oriented freestyle/racing build; SZ2306 V2 for value, flexibility, and everyday 5-inch freestyle.

    Good looking motor and the wires are easy to route. Install was simple, no bell rubbing, and all four spun clean.

    Sehr guter Motor for 6S freestyle. The 1950KV option feels right with 5 inch props and the quad corners cleanly.
