I would like to suggest that the x-axis label in the Vibrations screen be changed from "RPM" to "Frequency - Hz".
The reason for this is that users may confuse it for motor speed or head speed. These are already shown dynamically on the bottom line.
We do not understand where there could be any risk of confusion on the part of users.
It is really very difficult to get confused between Hz and RPM.
The horizontal scale shows RPM, and the numbers represented correspond to RPM (revolution per minutes) the vertical bar of the main rotor represents the actual RPM of the main rotor, the vertical bar of the tail rotor represents the actual RPM of the tail rotor, and the vertical bar of the motor represents the actual RPM of the motor (which could sometimes go off the scale beyond 30,000 RPM.
RC eli users know these values and can compare them with the values read by their optical RPM readers and their model manuals.
In forums and Facebook groups when we talk about propeller rotation values of main and tail blades and motor RPMs (nominal motor CV x battery pack volts).
Over the past decade, none of our users have ever complained or been confused regarding the value of RPM.
What would be the advantage of representing Hz since most RC pilots don't know what they represent, and if they do, then they would have to convert Hz (which is the measure of pulses per second) to RPM (which is the measure of pulses every 60 seconds) each time in order to be able to assess whether the vibrations correspond to the frequency of the main rotor of the tail rotor and the motor.
(In one minute there are sixty seconds, and even children know this.)
Those who want to know the value in Hz can simply multiply RPM by 60 (seconds).
