Product Description
The Castle 2535 520KV is the largest and most powerful motor ever produced by Castle in their 28+ year history. Designed to produce the torque and power for vehicles weighing up to 50lbs and up to 12s LiPo. When paired with the Castle Cobra 5 HV, the 2535 - 520kv can easily push 1/5th and 1/4th vehicles like the Losi 5IVE-T, 5IVE-B, or DBXL-E. It is the perfect upgrade for any 1:5 and 1:4 scale RC hobby vehicles (including gas to electric conversions) weighing up to 50 lbs. It also boasts features in their V3 motor design, including a larger rear bearing, direct to bullet winding connections, smooth can exterior making water cooling a breeze, and a stainless steel sleeve rotor.
Features:
- Running modes include Sensored and an ULTRA-EFFICIENT sensorless mode.
- High-strength, high-temperature grade neodymium sintered magnets combined with High-strength stainless steel sleeve wrap ensures the integrity of the rotor is not compromised during harsh running conditions.
- Oversized front and rear NMB bearings and vibration dampening system ensure the longest bearing life possible.
- Castle's proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.
- Updated modern and sleek design; looks as cool as it performs.

- Tech Notes: Running modes: Sensorless and Sensored / The 2535-520KV 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. 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.
