Build sheet The Parts Identified
First and foremost the Objective is to Build an Other than CHina Drone. Sell your sole to the commies to save a couple bucks, and sell out the US, well that's your choice. Myself being a military Vet who has family that fought against communism I wear my stripes on my sleeves. You want China Shit find it elsewhere. You want to say their product is better just realize it's all stolen technology. Thankfully America has a leader THAT IS STANDING UP TO CHINA. We at our company look forward to developing and manufacturing the components to bring the US to the leader of affordable hobby Drone Tech.

Dual GPS / GLONASS
GPS and GLONASS, allows the quadcopter to pick up many satellites. The dual satellite system is used to assist with precision flying, very precise hovering, return to home and much more.
This is the package we decided on for the electronics and mission capability
Flight Controller Selection
You should select a board that suits the physical constraints of your vehicle, the activities you wish to perform, and of course cost.
PX4 can run on many flight controller boards (see Autopilot Hardware, or the list of supported boards here on Github). A subset of the available options are listed below.
Pixhawk Series open-hardware flight controllers run PX4 on NuttX OS. With many form factors, there are versions targeted towards many use cases and market segments.
If you need computer vision or other computationally intensive tasks then instead consider a board with companion computing.
mRo Pixhawk Popular general purpose flight controller (this is a slightly updated version of the discontinued 3DR Pixhawk 1).
Also consider: HKPilot32, Dropix, mRobotics-X2.1.
Pixracer Very small/light autopilot optimised for FPV racers. It is suited to any small frame that requires no more than 6 PWM outputs.
Also consider: Pixhawk 3 Pro, MindRacer, Pixfalcon.
Pixhawk Mini Small general purpose autopilot that has been optimised for ease of setup.
The controller has internal vibration damping and only 8 main outputs (no AUX ports), making it much less daunting to install and connect. It is not suitable for vehicles/functions that require AUX ports.
Pixhawk 2 Flexible autopilot intended primarily for manufacturers of commercial systems. It is designed to be used with a domain-specific carrier board in order to reduce the wiring, improve reliability, and ease of assembly.
Pixhawk 4 Pixhawk 4 is optimized to run PX4 version 1.7 and is suitable for academic and commercial developers. It features more computing power and 2X the RAM than previous versions, additional ports for better integration and expansion, new sensors and integrated vibration isolation.
Autopilots for Computationally Intensive Tasks
These flight controllers (and development platforms) offer on-vehicle "companion computing", enabling computer vision and other computationally intensive tasks.
Qualcomm Snapdragon Flight A high-end autopilot computer that runs PX4 on the DSP (on QuRT RTOS). It includes a camera and WiFi.
Intel® Aero Ready to Fly Drone A UAS development platform that integrates a Linux computer, PX4 on NuttX, and a camera in a single package.
Raspberry Pi 2/3 Navio2 RaPi can be connected to an autopilot and used as a companion computer.
Commercial UAVs that can run PX4
PX4 is available on many popular commercial drone products, including some that ship with PX4 and others that can be updated with PX4 (allowing you to add mission planning and other PX4 Flight modes to your vehicle).

ESC settings, protocols, firmware
Nowadays, all ESC’s come with firmware pre-installed, most commonly BLHeli_S or BLHeli_32 depending on the hardware. Anyway this should be clearly stated in the product description.
make sure the firmware is up to date for bug fixes and improvement.
