Frequently Asked Questions

• Is the Hobbywing EZRUN 56118SD 650KV G2 motor suitable for beginners? — Whilst this is an advanced motor requiring compatible ESC and battery infrastructure, the sensored technology actually makes it easier to control than older sensorless designs. However, it's most suitable for intermediate to advanced 1/5th scale drivers who already have experience with large-scale brushless RC vehicles and understand battery safety protocols. If you're new to RC, we recommend starting with a ready-to-run kit before investing in individual motors.
• What battery does the EZRUN 56118SD 650KV need? — This motor is rated for 8-12S LiPo batteries, meaning you can use configurations from 8S (29.6V nominal) up to 12S (44.4V nominal). The no-load current is 5.5A, so under load with a typical 1/5th scale vehicle, expect to see considerably higher current draw — the paired ESC can handle up to 250A continuous. Your battery should be matched to the current demands of your specific vehicle setup.
• What makes the G2 generation better than previous Hobbywing motors? — The G2 generation introduces several meaningful improvements. The new sensor wire interface solves waterproofing issues that plagued earlier sensored motors, the modular detachable design makes maintenance far more convenient, and the sensored algorithm has been refined for even smoother operation. When paired with the EZRUN MAX5 HV G2 ESC, you get full sensored mode operation with improved performance across the entire throttle range.
• Can this motor be used with non-Hobbywing ESCs? — Technically, sensored motors can operate with many sensored ESCs from other manufacturers thanks to standardised sensor interfaces. However, Hobbywing strongly recommends pairing this motor with the EZRUN MAX5 HV G2 ESC to achieve perfect compatibility and to unlock the motor overheat protection function. When using non-Hobbywing motors with the MAX5 HV G2 ESC, the turbo timing feature cannot be activated.
• How does the sensored brushless system improve driving experience? — Sensored brushless motors use an encoder to precisely detect rotor position, allowing the ESC to engage the correct coils at precisely the right moment. This eliminates the sudden power surge you get with sensorless designs when the rotor aligns with the magnetic field, resulting in smoother throttle response, better low-speed control and more predictable handling. For competitive racing or technical trail driving, sensored operation is a significant advantage.
• Is this motor suitable for muddy and wet UK weather? — Yes, the IP67 waterproof rating means the motor is splash-resistant and water-resistant under normal use, and it can easily cope with mud, sand, dust and wet weather conditions. However, the rating assumes normal splash and water exposure — prolonged soaking should be avoided as protection may decline over time. Always rinse the motor with fresh water after running in muddy conditions.
• What vehicles is this motor compatible with? — The EZRUN 56118 is a 1/5th scale motor designed for large platform buggies and trucks. Specific examples mentioned include the Losi DBXL-E and Losi 5T Electrified. You can also use it with vehicles from ARRMA (such as the Kraton 8S and Outcast 8S) and similar 1/5th scale platforms, provided you have compatible mounting hardware. Always verify motor mounting compatibility before purchase.
• How much maintenance does this motor require? — The modular detachable design makes maintenance straightforward. You can separate the motor into its component parts (front end bell, stator set, rotor, rear end bell) for thorough cleaning, especially important after running in dusty or muddy conditions. Regular cleaning helps maintain efficiency and prolongs motor life. No internal brushes or commutator cleaning is required, unlike brushed motors.
• What's the difference between 650KV, 800KV and 1100KV versions? — KV (kilovolt) is the motor's speed constant — higher KV means more RPM per volt of input. The 650KV version (this model) offers the best torque and acceleration with 8-12S batteries, making it ideal for general driving. The 800KV provides a middle ground, whilst the 1100KV is for drivers wanting maximum top speed on smaller batteries (6-8S). Choose based on your battery voltage and whether you prioritise acceleration or top speed.
