The Flame Wheel F450 with Naza-M V2, GPS, and Landing Gear is a bundle from DJI that features a number of key components required when building your own quadcopter from scratch. If features the Flame Wheel F450 airframe (ARF) with landing gear, the Naza-M V2 flight control system with GPS, motors, ESCs, and a set of props. The Flame Wheel serves as the platform for the rest of the hardware to be installed on, including the bundled Naza-M modules as well as any accessories - such a video transmitter for FPV or iSOD unit - you may want to add.
The Naza-M V2 acts as the brains of the aircraft, managing pilot input and interpreting data from the various sensors, helping maintain a stable flying condition. There are four components to the system. The MC (main controller) houses the flight computer and is at the heart of the flight control system. Then there is the PMU (power management unit), which serves to regulate how much power is sent to each of the four, six, or eight rotors. Next is an LED unit for status display, which features a micro-USB port for connecting the Naza-M V2 to a computer when configuring or testing using the Windows assistant software. Finally, a GPUs receiver/compass combo is included, which enables a number of features, including Intelligent Orientation Control (IOC) and the Go Home failsafe.
Please note that this bundle is not a complete solution. In addition you will need a radio system such as the DT7, flight battery and charger, connection cables, and possibly other components, depending on the capabilities you require.
