Vibration Analyzer

The live vibration analyzer will show the current and the maximum vibration level on your heli as a fuction of the whole range of the vibration spectrum. These values can be inspected after the flight, too.

The graphic display shows the spectrum from 0 Hz (0 rpm) through 250 Hz (15,000 rpm) up to 500 Hz (30,000 rpm). Peaks should not exceed the dotted line. If they do, drift or loss of control may occur, since the sensors can no longer discern the noise from the actual signal. To help finding the cause of vibrations, do some math: 1,800 rpm by  60 sec equals 60 Hz, the cause would probably be with the main rotor. 9,000 rpm by 60 sec equals 150 Hz, the cause would probably be with the tail rotor. 15,000 rpm by 60 sec equals 250 Hz, the cause would probably be with the motor/engine. These are examples. Always also check rotating parts that run at the same rpm, like shafts and bearings for example, which also can cause vibration.

Use the Screenshot App to take screenshots using a momentary switch, even during the flight. Screenshots will be saved to VBar Control as .bmp-files. You can inspect them later, with VBar Control connected to a PC.

Setup Parameters

AR Bank allows to use a 4th bank/flight mode for autorotation (motor switched to OFF position). Default is Flight Bank, which means the selected bank 1-3 will stay selected even during bailout/autorotation.

Sensor Direction

Allows to set the alignment of the sensor independently from the setup wizard, depending on the actual situation on the model.

Warning Always pay attention to the Device- and Setup-Manuals provided with VBar Control, and the safety related topics therein.

Note This App needs only to be installed during setup. It is not necessary for the operation of the model.
