Here at Flying Tech we have a wide choice of electronic speed controllers (ESCs).
There are two main types of ESCs: 4-in-1 ESCs and single ESCs. A 4-in-1 ESC integrates four individual ESCs onto a single circuit board, each controlling a separate motor. A single ESC controls only one motor.ย
This 4-in-1 ESC is a more popular choice for racing quads, while single motor aircraft such as fixed wings would use a single ESC. Single ESCs are still used by some drone racers though, as after a crash or a burnt up ESC, they only have to replace one, not an entire 4-in-1 or stack which is a lot more costly. Single ESCs are also available which much greater current ratings (80amp +) so they are also used by power hungry multi-rotors, for example X-Class racing quads, professional camera flying โCineliftersโ.ย
When using individual ESCs, they typically need to be connected to a single power distribution board (PDB) or an โAIO flight controllerโ (a type of flight controller with integrated PDB) for power supply.
