This new ESC increases the maximum input voltage to 4s. We also added DATA LOGGING and our CRYO-DRIVET TECHNOLOGY; CryoDrive allows the ESC to run cooler and more efficiently at partial throttle. Like its predecessor, it is waterproof and has SENSORED MOTOR SUPPORT. This ESC and Motor Combo is ideal for 1/14th and 1/16th scale vehicles, weighing up to 3lbs and up to 4s LiPo. Important Product Update, 8/2/2022. Due to ongoing supply chain disruptions, we have been unable to manufacture the Micro X2. The parts in question are integral to the onboard 2-amp BEC. This upgraded BEC has a wider range of BEC voltages and much higher current capacity. The retail price for the ESC and combos has not changed. If running on 4s, and using two 2s LiPos in series, please refer to this BEC wiring diagram. FEATURES: Input Voltage range 2S-4S. Waterproof design, included CC BEC is not waterproof. Sensored Motor capable Convenient transmitter programming for six common adjustable settings. BUS2 Telemetry Link and Futaba T4PX, T7PX and T7PXR transmitters Auxiliary Wire Functionality allows for “on-the-fly” adjustments such as Max Power and Max Brake. Audible Alerts that will notify you of possible issues with calibrations and error conditions. If unit is operated in wet conditions, rinse with fresh water to remove dirt or corrosives, then fully dry unit. Technical Specs Mamba Micro X2 ESC Input Voltage Range. 2S-4S LiPo (16.8V Max) BEC Specifications. No internal BEC in ESC. External 10-amp CC BEC Included. Waterproof design allows for use in nearly any environment; included CC BEC is not waterproof. Yes, but may be disabled On/Off Switch. Yes, waterproof Cooling Fan. 41.6 mm x 29.4 mm x 21.3 mm 1.64″ x 1.16″ x. 84 Weight (with wires). 1.66 oz / 47 grams Connectors. 4.0 mm bullets Items Needed for Operation. Battery Connector required: Castle 4.0mm Polarized Connectors, Deans Ultra Plugs and XT60 are recommended. Recommended battery capacity for 1:18 scale vehicles is 1500mAh. We recommend using 30C continuous discharge or higher LiPo batteries (or high quality 25C batteries such as Traxxas® Power Cell). Mamba Micro X has 4.0mm bullet connectors on the motor wires and the battery input wires are bare. You must add the connector of your choice to the battery leads. We recommend a high current connector rated for at least 40 amps. Yes, with Castle Creations Telemetry Link for S. BUS2 and Futaba T4PX and T7PX Transmitters. Although the Mamba Micro X2 is waterproof, it is not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC with clean water after exposure to corrosives or dirt. While the controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind. Length: 59.5mm Diameter: 28.25mm Weight (w/wires). 5.17oz (46.5g) Shaft Size. Length: 15mm Diameter: 1/8 (3.17mm) Mounting Hole Specifications. 4mm male Castle Bullet Connectors attached to replaceable 16 gauge wire; includes 210mm length sensored wire. Ideal for 1/14th and 1/16 vehicles weighing up to 3lbs and up to 4s LiPo Max. Running modes: SmartSenseT Sensored and an ultra-efficient Sensorless mode. Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommends applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments. We are an authorized dealer of every product we offer in our store.
