I'd like to know what does 3d mode do when it come with a helicopter?
3d mode - better known as 'idle up' - puts the helicopter into its full aerobatic configuration.
This enables full negative and positive collective pitch, giving the heli extreme manoeuvrability.
That is a simplification, as it enables other things such as different throttle curves, control throws etc., and is not for the fainthearted! Hahah!
