Product overview
The DYS BE5208 is a propulsion component for multicopters, built around an outrunner brushless architecture. Its published integration envelope is 63 mm in diameter by 30 mm long, with a 5.0 mm shaft and a listed mass of 200 g; these manufacturer values should be confirmed for the selected configuration. Internally, the specification identifies a 52 mm stator diameter and 8 mm stator length. The BE-series construction description names 0.2 mm Kawasaki silicon steel, 40UH magnets, NSK bearings and a CNC-machined shell.
The documented configuration is 330 KV, with load measurements identified as BE5208-25 (330KV) and a published battery range of 3–6S LiPo. This is a motor listing, rather than a complete flight platform or airframe kit. Its 3300 g headline pull corresponds to the listed 6S, 18 × 5.5 APC propeller condition, drawing 28.2 A at 626.0 W. Procurement should therefore retain the battery and propeller qualifications and confirm the chosen ESC, despite the manufacturer’s broad BE-series compatibility claim.
