Unity Pro 3500kv 2-in-1 Micro FOC Brushless System for Redcat Ascent-18 (FTK2573)

The Unity Pro 3500KV 2-in-1 Micro FOC Brushless System for Redcat Ascent-18 is a compact unit that combines a brushless motor and ESC in one package, designed as a drop-in upgrade for the Redcat Ascent-18 crawler. With field-oriented control (FOC) for ultra-smooth throttle response and consistent power, it helps crawlers climb rough terrain with precision. The enclosed case shields the electronics from dust and water for reliable operation in challenging conditions, while a built-in 5A BEC provides multiple voltage options (5.5V, 7.4V, 8.4V) to power high-torque servos without an external regulator. A dedicated power switch on the unit adds convenient on/off control and helps prevent unnecessary battery drain.

Designed as a drop-in upgrade for Redcat Ascent-18 and suitable for 1/24 and 1/18 scale crawlers, this 2-in-1 system delivers a streamlined, compact solution. The Furicar app (Android and iOS) offers real-time telemetry, live tuning, and easy programming, with lifetime firmware upgrades to keep performance current. Firmware refinements also improve startup smoothness as the system reaches the FOC stage, providing precise, reliable power and enhanced control for serious crawlers.
