The Castle 2028 Extreme 800KV motor now has an IMPROVED 4-POLE 12-SLOT design that boasts exceptional EFFICIENCY and produces LESS HEAT. If you need LARGE-SCALE POWER for LARGE-SCALE VEHICLES the new BRUSHLESS SENSORED 2028-800KV motor will no doubt hold up to the heavy throttle and extended usage that 1/5th scale vehicles like the Losi 5IVE-T, 5IVE-B or DBXL-E encounter. It is the perfect upgrade for any 1/5 scale RC hobby vehicles (including gas to electric conversions) weighing up to 30 lbs for 2WD and 25 lbs. for 4WD. The 2028 Extreme can easily run in the 10 horsepower range*
*Burst power output for durations typical of vehicle acceleration.
FEATURES:
- Running modes include Sensored and an ULTRA-EFFICIENT sensorless mode.
- High-strength, high-temperature grade neodymium sintered magnets combined with High-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions.
- Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible.
- Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.
- Dual sensor ports to ensure optimal installation in your large-scale vehicle.
- Updated modern and sleek design; looks as cool as it performs.
Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it, resulting in a cooler running motor. A cooler motor has a longer lifetime. Construction of our motor required careful component selection; each verified through internal testing to ensure the HIGHEST EFFICIENCY possible. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn't put our name on anything less.

| Tech Notes: | Running modes: Sensorless and Sensored
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 recommended 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. |
