Product overview
The Flash Hobby BE 1104 Brushless DC Motor is recommended for 2–3 inch propellers. Its 14 x 12.5mm package weighs 6g including the cables, with an 11mm-diameter stator measuring 4mm high. Construction combines a 9N12P configuration, NSK bearing and 6061 aluminum bell. Mechanical integration uses a 1.5mm shaft and a 9x9mm mounting screw pattern designated M2*4. The motor cable is a 150mm three-pin wire, providing a defined cable length alongside the compact motor dimensions.
The motor comes in 4000KV, 5400KV, 6500KV, 7500KV and 10000KV versions, with custom KV also offered. Respective maximum-pull ratings are 118g, 170g, 200g, 220g and 227g, each specified with 2S/GF3020. Corresponding currents are 3.5A, 5.4A, 9.0A, 11.8A and 15.3A; maximum powers are 25.9W, 59.9W, 99.9W, 131W and 169.8W. All five versions have a suggested 7A~12A ESC. Input voltage is DC7.4-11.1V(1-2S) for the first two versions and DC7.4-11.10V(1-2S) for the remaining three.
