Product overview
The FlashHobby D4215 Brushless DC Motor is a three-phase outrunner intended for 10–12 inch propeller applications. It is offered at 650KV, with custom KV options available. The D4215-650KV operates on DC14.8–22.2V (4–6S), with a specified current of 39A and maximum power of 868W. A 40A–60A ESC is recommended, and control uses an adjustable PWM signal over a 900–2100US range. Maximum pull is 2290g with the stated 6S/APC1238 setup, and the working temperature range is -0°C to +80°C.
The motor combines a 6082 aluminum bell, an NSK bearing and a 12N14P configuration. Its 42 × 15mm motor size encloses a stator measuring 36mm in diameter and 8mm in height, while the shaft diameter is 4mm. Mounting uses a 16 × 19mm screw pattern with the M3*4 designation. The motor has 200mm 18#AWG cables, and its 83g weight includes those cables. These dimensions define the motor’s physical mounting and connection arrangement.
