Frequently Asked Questions
- Is the Hobbywing EZRUN 5687 suitable for beginners? — This is a modified-class brushless motor designed for experienced RC enthusiasts rather than beginners. It requires proper ESC pairing, battery management knowledge, and understanding of brushless motor operation. If you're new to RC, consider starting with a complete Ready to Run RTR setup that includes all necessary electronics pre-configured.
- What battery does the EZRUN 5687 require? — The motor itself is compatible with LiPo batteries across a wide voltage range. Your specific battery choice depends on the ESC you pair with it. The recommended Hobbywing EZRUN MAX5 ESC supports batteries ranging from 3S to 8S LiPo configurations. Check your ESC specifications for exact battery compatibility.
- Does this motor include thermal protection? — The motor includes a built-in temperature sensor port that activates thermal protection features when paired with a compatible ESC like the Hobbywing upgraded MAX5 ESC. Without a compatible ESC, you won't benefit from active thermal protection, though the excellent heat dissipation design of the aluminium case helps manage heat naturally.
- What is the difference between the EZRUN 5687 and other brushless motors? — The EZRUN 5687 stands out with its industry-leading 90% efficiency rating, sensorless brushless design that simplifies installation, CNC-machined hard anodised aluminium construction, and seamless integration with Hobbywing MAX5 ESCs for thermal protection and smooth power delivery. The 1100KV rating makes this motor particularly well-suited for torque-focused applications and high-performance driving on 1/5 and 1/6 scale vehicles.
- Can I use this motor with any brushless ESC? — Whilst the motor can work with most brushless ESCs featuring 6.5mm bullet connectors, Hobbywing strongly recommends pairing it with the EZRUN MAX5 ESC to unlock the thermal protection features and achieve the excellent torque and smooth linear power band that makes this motor-ESC combination exceptional.
- What does sensorless mean? — Sensorless brushless motors don't require sensor wires to communicate with the ESC. This simplifies wiring, reduces potential failure points, and makes installation more straightforward. The trade-off is that sensorless motors may have slightly less smooth startup compared to sensored motors, though the EZRUN 5687's advanced design minimises this difference.
- Is this motor waterproof? — The motor itself is not fully waterproof, though the hard anodised aluminium case and sealed bearings provide excellent protection against casual water exposure. For salt water or submerged operation, additional waterproofing measures should be considered, and thorough rinsing after salt water use is essential.
- What shaft diameter does this motor have? — The motor features an 8mm polished alloy steel output shaft, which is the standard shaft size for many 1/5 and 1/6 scale RC vehicle platforms. Ensure your vehicle platform is compatible with 8mm motor shafts before purchasing.
