SEQURE is a widely known firm on the planet of FPV (First Particular person View) resulting from its wonderful pen-style soldering irons. These days, it has additionally began offering FPV drone elements for the neighborhood. On this evaluation, we can have an in depth have a look at its highly effective flight stack, GPS module, and ELRS radio receiver.
Constructing an FPV drone entails a number of steps, together with choosing elements, assembling the drone, configuring the flight controller, and establishing the FPV system. Along with these SEQURE FPV Elements, you’ll need a body, propulsion system (motors and propellers), and FPV system (VTX and digicam) to construct your drone.
The flight stack is the center of an FPV drone. It’s often put in within the heart of the body and comprises two boards: the flight controller (FC) and the ESC (electrical velocity controller).
