Below are some details on my 2nd H Quad scratch build.
I got the motors & speed controllers as a set from Amazon
LHI 920KV motors & 30A ESC’s Flashed with SimonK
A few options for the flight controller:
A older but still useful board for a basic camera ship Quad. big benefit is the simple setup via the buttons and screen directly on the board, No PC or Lab top needed.
A popular board for racing drones, setup is done thru a PC or Lab top running Libre Pilot
The red is to blue, ford is to chevy, yet another popular board with race quads.
