Hobbywing XERun AXE Plus R3 ESC Combo With AXE 540L 2800Kv R2 Motor

The Hobbywing XERun AXE Plus R3 ESC Combo with AXE 540L 2800Kv R2 Motor (HW38020388) delivers precise, quiet and efficient crawler control. Leveraging FOC (Field-Oriented Control) and a sensored 4‑pole motor with a high‑precision magnetic encoder, this pairing provides ultra‑smooth startup, minimal cogging and consistent speed under load. Built‑in Bluetooth simplifies setup via the HW LINK app, while IP67‑rated protection and robust safeguards inspire confidence on the trail.

Engineered for deliberate, technical driving, the AXE Plus R3 offers a powerful adjustable drag brake (up to 200%), a Super BEC with three selectable voltages for modern servos, and smart torque delivery to keep momentum controlled on climbs and descents. Practical details such as XT60 connector, 12AWG leads and a 25mm cooling fan round out a dependable, crawler‑focused system from Hobbywing.
