The Impact of Capacitor Wire Length on Gyroscopes

The shorter the capacitor wires and the closer they are to the ESC, the better the filtering effect.

Firstly, let's examine a comparison. The data in this image comes from the same aircraft, with the only difference during the data collection being the length of the capacitor wires.\

It is evident that with shorter wires, the overall noise is cleaner (less yellow area), and the gyroscope data becomes much clearer. This significantly benefits by reducing the heat generated by the motors and decreasing the operational stress on the ESC.

The impact of filters on the overall performance of an aircraft

Firstly, better filtering reduces unnecessary motor signal output, resulting in cleaner and more precise flight maneuvers.

Simultaneously, with an increase in effective signals, motor heat is reduced, and the demand for electrical current decreases, leading to more efficient power usage.

The reduction in temperature also helps prevent issues like demagnetization due to heat in flight controllers, which can cause step loss. Utilizing bidirectional DSHOT for RPM filtering effectively mitigates motor noise, so it's recommended to enable bidirectional DSHOT in cases of step loss.
