Caelus 2306 is a high-performance motor optimized for 6S battery systems and 5-inch propellers, primarily targeting racing and freestyle flight. The 23mm diameter and 6mm height provide exceptional magnetic force and torque. This allows the motor to accelerate exceptionally quickly when propelling the 5-inch propeller, and enables clean and crisp maneuvers such as sudden stops, turns, and rapid ascents without any lag.
