Description The Redox IBL 540/3300 inrunner brushless motor is a versatile unit primarily designed for RC cars and boats, but it's also suitable for gliders. This 3300kV version boasts the highest RPM and highest power output among all IBL 540 class motors. It generates a powerful 395W, though this comes at the cost of slightly higher energy consumption. We recommend it for "sprinters" who prioritize speed and acceleration over battery run time. It also requires a more powerful ESC (we recommend 60A or even 80A). It's an ideal replacement for brushed motors in the 540 and 600 class (3.2mm shaft and 35.8mm diameter). For use in boat models, due to high current consumption (and thus higher operating temperatures), we strongly recommend purchasing a dedicated Redox water cooling jacket (not included in the set). Operating Parameters: Power: 395 W Static Thrust: 680 g (if used in aircraft models) Shaft Diameter: 3.2mm kV [RPM/V]: 3300 Operating Voltage: 2-4s (7.4 - 14.8V) No-load Current: 3.25 A Max. Current Draw: 35.53 A at 7.4V Recommended ESC: 60-80 A Propeller (if used in aircraft models): APC 6x5 E Weight: 163 g Motor Diameter: 35.8 mm Body Length: 52 mm Water Cooling Ready: Yes (dedicated water jacket not included - available at this link: IBL 540 water cooling)
