Hobbywing QUICRUN Fusion Pro 2300KV Elite — Compact 2-in-1 Motor/ESC for 1/10 Scale Crawlers

Overview

Discover the Hobbywing QUICRUN Fusion Pro 2300KV Elite, a compact integrated power unit designed to simplify builds on 1/10 scale crawlers. At just 48.5 mm in length, this 2‑in‑1 motor and ESC fits tight installations, helping you achieve a clean, tidy setup with minimal routing.

Rated for 2‑4S LiPo batteries and a continuous output of 50 A, it provides stable, responsive power without the bulk of separate components. The compact design and efficient current handling make it a versatile choice for a wide range of trail, rock crawling, and rally applications while maintaining reliable performance across demanding terrains.

Trail‑ready performance

The system employs Field-oriented Control (FOC) drive for quiet, linear torque and smooth power delivery. A sophisticated closed‑loop torque control actively adapts to changing terrain, helping you maintain throttle finesse when negotiating obstacles or negotiating steep descents.

Real‑time tuning and control

Real-time parameter adjustment is possible by wiring the yellow AUX CH signal to an unused receiver channel. This lets you tweak settings like drag brake on the fly from your radio, making on‑trail tuning faster and more hands‑on without pausing to re‑program.

Durability and protection

With IP67 all‑terrain protection, the Fusion Pro Elite resists water, dust, and dirt under typical use—ideal for rain, mud, sand, or splashes. Note that protective performance may decline with aging and prolonged submersion is not advised.

Key features at a glance

• Compact yet powerful 2‑in‑1 motor and ESC
• 4S power output with 2‑4S LiPo compatibility
• 50 A continuous current rating
• Built‑in 10 A BEC with selectable 6/7.4/8.4 V
• Five selectable operating modes
• LED and LCD Pro Program Box compatibility
• FOC drive for quiet, strong low‑speed torque
• Closed‑loop torque control for precise throttle matching

What you can expect in use

Expect a clean, compact installation that frees up space for wiring and connectors. On the trail, you’ll notice improved low‑speed torque and steadier control on rough terrain, with a built‑in BEC capable of powering servos and accessories like lighting without extra hardware. While IP67 protection handles typical exposure, avoid prolonged immersion and maintain regular checks as parts age over time.

Why builders choose it

• Enhanced low‑speed response for crawlers
• Minimal wiring footprint for tidy builds
• Quiet operation reduces overall noise during trail runs
• On‑the‑fly parameter tuning improves on‑trail adaptability
