Overview
The VCI SPARK 1407 brushless motor is a compact outrunner motor series for FPV drones and other small RC airframes. It is offered in multiple KV options (1950KV, 2200KV, 2650KV, 2850KV, 3200KV, 3650KV) so builders can match propeller size and battery voltage to the desired efficiency and throttle response.
Key Features
- 1407 stator size (Ă14*L7mm) with 9S12P configuration
- N52SH arc magnets
- 1.5mm shaft diameter, 3mm shaft length
- 24AWG silicone wire, 100mm length
- 4x M2 equally spaced mounting pattern
