If you want to go faster, run harder, and leave limits behind, the Cobra 5 ACE is your next upgrade.

MOTOR

The Castle 2028 1100KV 8 mm shaft motor is a 4 pole 12 slot brushless sensored design that focuses on efficiency and reduced heat. For hobbyists who need large scale power in large scale vehicles, this motor is built to handle heavy throttle use and extended run time in 1/6 scale platforms such as the Arrma Kraton 8S and Traxxas X Maxx. It is a strong upgrade option for 1/6 scale RC vehicles, including gas to electric conversions, up to a recommended vehicle weight of 30 lbs. Under typical acceleration bursts, the 2028 Extreme can operate in the 10 horsepower range*.

*Burst power output for durations typical of vehicle acceleration.

🔥FEATURES:

  • Running modes include sensored operation and an ultra efficient sensorless mode.
  • High strength, high temperature grade neodymium sintered magnets with a high strength Kevlar wrap help the rotor maintain integrity under harsh running conditions.
  • Oversized NMB bearings and a vibration dampening system are used to support long bearing life.
  • Proprietary winding techniques are designed to lower stator resistance, which supports cooler motor operation.
  • Dual sensor ports provide flexibility when installing the motor in large scale vehicles.
  • Modern, sleek industrial design that looks as refined as it performs.
  • Improved 4 pole 12 slot design that targets high efficiency and reduced heat generation.
  • QUIETSENSE™ technology helps shield the sensors from magnetic field noise created by the motor coils and keeps the motor and ESC synchronized. A Flux Shield™ and secondary sense magnets are used to support precise and efficient startups.
  • An optimized sensor based design removes the need for mechanical timing adjustments. The sensor alignment method is intended to provide uniform timing and torque in both directions.
  • Updated visual design that aligns with Castle’s current motor lineup.

Large scale RC drivers often push their equipment close to its limits. Castle’s engineering approach for this motor focuses on combining efficiency with robust construction so it can cope with demanding conditions. Component selection and internal testing are aimed at achieving high efficiency and reliable performance over time. The 2028 1100KV is intended to deliver strong output, consistent operation, and durability in heavy duty applications.

With the right setup, you can benefit from longer run time on a single pack and a motor that operates at cooler temperatures compared to less efficient designs. This leaves more headroom for demanding gearing choices and high load situations, when used within recommended limits.

When combined with a compatible Castle ESC and the Castle Link system, users can access advanced tuning options. Many drivers use Castle Link to fine tune throttle response, braking, and other settings for sensored motors in their specific vehicles.

SMARTSENSE™ uses the motor’s sensors during startup to provide smooth launches, strong low speed torque, and good drivability. Once the motor is up to speed, the system transitions to a high efficiency sensorless mode. Because a motor experiences different load conditions throughout a run, the timing needs change as well. Mechanical timing alone can only be optimized for a narrow operating condition. Electronic timing in SMARTSENSE™ adjusts timing automatically in an effort to maintain performance and efficiency across a wide range of driving conditions.

When this motor is paired with a Castle sensored ESC, users can build a very capable power system for large scale vehicles. The combination is designed to offer precise throttle control, smooth starts, strong performance, and efficient operation across the throttle range. The goal is a power system that feels powerful yet manageable, while also supporting longer run times when geared appropriately.

SMARTSENSE™ is intended to combine the advantages of sensored startup with the efficiency of sensorless running in a single hybrid control strategy.

Product Use Statements: Monitor motor temperatures closely; overheating a motor will cause permanent damage to the magnets. Never exceed 180°F on the motor or ESC.
Do not use mounting screws that extend more than 5mm into the front of the motor. Using too long of a screw can result in damage to the motor's windings and will not be covered by the warranty.
Application Guidelines:

The 2028-1100KV is a 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. We recommend 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.


Recommend starting gearing (pinion/spur) for 8s operation:
Traxxas X-Maxx - 23/35 (mod 1.5) or 34/54 (mod 1.0)
Arrma Kraton 8s - 32/47

Tire size, driving style, driving conditions, battery quality and connectors can impact performance and acceptable gearing.
