The fpvmanuals FM-4008 is a new 620kv multi-rotor motor in the popular 40mm stator class. This motor features 13"/330mm long motor cables to enable you to mount your ESC in the center of the frame. The motor is most efficient with a 10" prop such as a Graupner E-Prop 10x5 or an APC 10x4.7. We recommend an ESC 18amps or higher. The motor features a threaded 4mm steel shaft and an included aluminum spinner. No prop adapter is needed. The motor also comes with 2 shaft size adapters to bring the shaft diameter to either 5mm or 6mm respectively. This enables a wide variety of props that may only come with a specific size locator ring. The 4 mounting holes are 25x25mm across from each other. This mounting hole pattern is only found on a select few multi rotor frames such as the QAV500 for which we developed this motor. Please note that this motor can not be mounted on the Pro Tricopter Delrin Kit.
M3 mounting screws/hardware not included.
