2.) A new 40mm stator motor called the FM-4008

This motor also has long motor cables. It also features a thicker 4mm shaft compared to the 3mm shaft of the NX-4008. The motor comes with 2 aluminum shaft rings to get the shaft to be 5mm or 6mm in diameter. This beefed up NX-4008 also does not use a prop adapter or integrated prop saver anymore. Instead, this motor uses a threaded steel shaft with an aluminum spinner. This motor has mounting holes that are 25x25mm apart. This pattern is supported by the QAV500 FPV Quadcopter frame. You will not be able to mount this motor onto the Pro Tricopter Delrin Kit.

Specs

Both motors have the same 40mm stator and 45mm total diameter. They are also wound identically and will produce similar thrust.
