ETHOS offers several flight modes for various models such as quadcopters, airplanes, gliders, and helicopters, and each mode has a specific window for regular settings or customized mixer functions. Some basic functions like telemetry feedback, value settings, audio functions (RSSI alert, setting beep, music play, etc.), supports LUA scripts (in progress), and small tools are all perfectly supported by ETHOS.
The graphical representation is a very popular way to indicate functions with different UI designed icons that can give a better understanding of the ETHOS for beginners. Equipped with a color-display screen in collaboration with the intuitive animation tutorial makes the pre-flight preparation work easy and fun.
ETHOS also provides a PC simulator that can give the interested people an initial and basic experience of this system.
ETHOS allows the system operation more flexibility using the Touch and Non-Touch Modes. Assigning and setting output channels at will, becomes ever easier thanks to the Touch Screen.
Apart from the supported built-in TANDEM, ACCESS, and ACCST D16 protocols, ETHOS also adds an external RF module option to pair its Lite version module interface that supports working compatibly with R9M Lite, R9M PRO Lite, XJT Lite, etc.
