What are the usual engineering considerations for a UAV current sensor?

Is the shunt resistor usually mounted high-side (i.e. at the positive battery terminal), or low-side (at the negative terminal), and why? Does it matter? There should be no significant difference ...

Is it a good practice to use a throttle limit of 90% for racing builds?

There are two reasons to throttle limit, one is obvious, the other is not necessarily obvious. The first reason is that both thrust and amperage draw grow rapidly at higher throttle values, and ...

Is it a good practice to use a throttle limit of 90% for racing builds?

The reason why this is recommended for racers is likely due to the fact that during these high-throttle punches, the voltage of the battery sags from the load and so more current is pulled from the ...

What are the usual engineering considerations for a UAV current sensor?

Using PM07 power management board from Holybro as an example. They use shunt resistor on the high side. Voltage across the shunt resistor is then fed into the Texas Instruments INA169 current sense ...
