Product information "Hobbywing Ezrun MAX4 HV Combo 70125 560kV" The Ezrun MAX4 ESC works best with the included 70125 SD 560kV motor for extra large 1/4 and 1/5 scale models. This fully sensor-controlled combo can be used in many ways in such models, whether it's a heavy-duty off-roader or a truck. So if you like large models and You want the most fun out of it, the MAX4 combo is high-quality equipment that literally bursts with exploding power. And even with its enormous size, care was taken to use high-quality and, above all, durable materials in the construction. After all, both the ESC and the motor should ensure that driving fun lasts as long as possible. Even the electronic switch is well protected against damage. In addition, the Ezrun MAX4 has a built-in super high-current BEC, which can provide a max. output power of up to 25A. The output voltage can be switched between 6V, 7.4V and 8.4V. The high-current BEC was developed in such a way that it can supply the current high-current servos with sufficient power if required, and thus be able to precisely control the appropriate large models. Features: Full sensored combo Super powerful switch mode BEC with a constant current of 10A, instant 25A and the ability to switch between 6V, 7.4V and 8.4V Fireproof circuitry to protect the battery connector, as well as many built-in protections Versatile programmable Real time data recording CNC-milled aluminum housing, 0.2mm silicon steel sheets and other high-quality building materials Four sintered NdFeB magnets for super torque, stable performance and explosive power Innovative new sensor interface Waterproof and dustproof thanks to the rubber cover of the bearings Independent, high-precision encoder in the motor to communicate the rotor position without any interference More power and less heat development with the same load Technical Specifications: ESC Current (cont./peak) 300A / 2000A Motor Type: Sensor/Sensorless Brushless Motors Motor Limit: 12S LiPo: kV <= 600 (70125) Cells: 6-12S BEC: 6V / 7.4V / 8.4V @ 10A (adjustable) Fan: Yes (powered by BEC) Programming Input: Fan/ PRG-Input Programming: LED Programm Card, LCD Programm Box, OTA Bluetooth Programm Module Dimensions: 125x85x61.7mm Weight: 775.4g Application: 1/4 and 1/5 Heavy Duty-Off-Road, Trucks Motor Sensor Type: Sensored Poles: 4 kV Rating: 560kV Cells: 8-12S No-Load Current: 3.6A Outer Diameter: 70mm Length: 125mm Shaft Diameter: 8mm Shaft Length: 30mm Weight: 1995g Application: 1/5 Heavy Duty Off-Road, Truck Delivery: 1x EzRun MAX4 ESC 1x EzRun 70125SD Motor with 560kV 1x Manual
