Hello! I show to you my current work of new mod.
1. I have added a few bars in interface: blue bar-fuel( it already in game, but it is not work with my hovers. It don't show me real level of fuel) and yellow bar- fuel consumption. You can set in the designer the relativety value, and yellow bar will show you fuel consumption relativety this value.

2. Hover have a sound and effects. Yoy can disable it. Also, in the designer you can see the thrust of each hover, its area and fuel consumption.

3. You can disable each hover.

The fuel consumption depend from the rpm. But the thrust depend from angle of blades. This means that the fuel will burn even if you set alt =0 in the game.
May be, hover will have a special mod when they become more powerful. But if you don't turn off this mode, the hovers will explode. I think its will be interesting.
