Crazy Plane function?

[SirGoul]

Hi, I just updated my FlySky successfully to the 10ch Version. While setting up my planes I found a crazy function. While within the Display View of the transmitter, hit and hold the cancel Button. The transmitter will start some kind of demo ... which is quite bad when your plane is connected and is within your livingroom.... it will go mad even if the throttle hold sw is enabled.

Does anybody else knew this function? What is it good for?

@SirGoul sure - it is well known - but don't remember it it was added by Dave or it was part of oryginal firmware.

any chance to disable it?
