Technical Performance

The Hobbywing EZRUN 1626SD 3500KV is an engineered marvel of brushless motor design, specifically tailored for the demanding world of 1/28th scale RC car racing. With a compact outer diameter of just 16mm and a length of 26mm, this motor delivers tremendous power from a diminutive package that won't add unnecessary weight to your chassis. The 2-pole brushless design operates with sensored control, using high-precision hall-effect sensors to ensure smooth commutation and precise throttle response at all speeds. The 3500KV rating is perfectly suited for 2S LiPo battery systems, offering an ideal torque-to-speed balance that maximises both acceleration and top velocity.

At just 18 grams, this motor is exceptionally light, making it an ideal choice for 1/28th scale builders who understand the importance of weight distribution and chassis balance. The sensored brushless technology eliminates the maintenance burden of brush replacement whilst delivering the smooth, responsive power delivery that only brushless motors can provide. The no-load current is just 0.4A, indicating exceptional efficiency and minimal power wastage. When used with the EZRUN Mini28 ESC, this motor can achieve extraordinary performance figures, with timing advance adjustments unlocking an impressive 40% increase in maximum speed — a capability that separates genuinely competitive equipment from standard offerings. The motor's efficiency advantage of approximately 5% over competing motors, combined with 6% greater output power and demonstrably lower temperature rise under identical loads, makes it an exceptional choice for serious racers who demand every advantage. The high-density 4-layer PCB architecture ensures reliable solder connections that can handle the demanding electrical loads of competition racing, whilst the precision-machined aluminium case dissipates heat effectively, keeping operating temperatures optimal even during extended running sessions.

Frequently Asked Questions

• What is the difference between the 3500KV and 5000KV versions of the EZRUN 1626SD? — The 3500KV version (this model) is optimised for maximum torque and mid-range performance, making it ideal for general 1/28th scale racing and mixed track conditions. The 5000KV version offers higher top speed but with slightly reduced torque characteristics. The 3500KV is the more versatile choice for most racing applications. The 6500KV is designed for drivers seeking absolute maximum speed on faster tracks.
• Is the EZRUN 1626SD 3500KV suitable for beginners? — Whilst this motor is engineered for competition-level performance, it is absolutely suitable for beginners to 1/28th scale RC car racing. The sensored design provides smooth, predictable power delivery, and the no-load current of just 0.4A means it is forgiving on battery systems. However, you will need to pair it with a compatible ESC such as the EZRUN Mini28 and ensure your chassis is designed for this motor size.
• What battery does the EZRUN 1626SD 3500KV require? — This motor is optimised for 2S LiPo batteries, which provide the perfect voltage and current characteristics for this KV rating. A 2S LiPo battery (7.4V nominal) will deliver optimal performance and longevity. Never exceed 2S voltage or use alternative battery types, as this will damage the motor and ESC.
• How much faster will my 1/28th scale RC car be with the EZRUN Mini28 ESC? — When using the EZRUN Mini28 ESC with timing advance adjustments, you can expect approximately 40% more top speed compared to standard timing settings. This is a genuinely significant performance increase that can provide a competitive advantage during racing.
• What makes the EZRUN 1626SD more efficient than competing motors? — The motor achieves superior efficiency through several engineering advantages: the ultra-thin 0.2mm silicon steel laminations reduce eddy current losses, the premium 200°C temperature-resistant copper windings deliver optimal electrical conductivity, and the 4-layer PCB design minimises electrical resistance. These combined improvements result in approximately 5% greater efficiency and 6% more output power than similar competing motors.
• Does the EZRUN 1626SD have screw holes for mounting? — No, this motor is designed to mount in a cradle or similar mounting solution rather than directly to screw holes. Ensure your 1/28th scale chassis features a compatible motor cradle before purchasing.
• Is the EZRUN 1626SD sensored or sensorless? — This motor features sensored design (indicated by the SD designation), meaning it includes high-precision hall-effect sensors for smooth commutation and precise throttle response. Sensored motors deliver superior low-speed response and more predictable power delivery compared to sensorless alternatives.
• Can I use this motor with other ESCs besides the EZRUN Mini28? — Theoretically, this motor can be used with other sensored ESCs designed for 1/28th scale applications. However, the EZRUN Mini28 ESC is specifically engineered to work with this motor and unlock its full potential, particularly the 40% speed increase through timing advance. Using other ESCs may limit performance capabilities.
• How durable is the EZRUN 1626SD for competitive racing? — This motor is specifically engineered for the rigours of high-performance competitive 1/28th scale racing. The high-strength explosion-proof rotor, high-resistant output shaft, and precision ball bearings ensure exceptional durability and reliability. The modular detachable structure makes maintenance straightforward, allowing you to keep the motor in peak condition.
