The device has a gear-box control mechanism (30) with a control lever/stick (20) located at two axes (X, Y). Movement of the control lever/stick is guided by a grid (11) including a guiding path, which allows the differentiation of different positions of the control lever/stick. The grid presents a spherical form/shape from a centre, which is an intersection point of the axes (X, Y). One of the axes (X) is noticeably orthogonal to other axis (Y). |
