I´m using fuel pods on Stilettos and it works fine. In fact, it it´s working as supposed. I reduce the stiletto range to 2000 km and increase the cruise speed to 1330 km. I mount only one fuel tank and the range increased to 4000 km, but the speed drop to 1200 km. I change the fuel capacity of the tank to +10 and the drag to -5%. The reason? the %% is the normaly drag of a fuel tank.
Weight is more important, because more of it, you need increase speed or air density (reducing altitude), but the first uses more fuel and the second increase drag.
I don´t know if the game uses a drag and lift ecuations to simulate speed droping, but with the firebird the decrease of range it´s dramatic. With my mod, i need the fuel tanks because i reduce the craft range for a more realistic game. By the way, lift ecuation is not needed because this is not an air simulator, but it could be possible and easy to use the drag ecuations for a more realistic calculation. The weight implications could be estimated by a percentage.
If you want, i can help with this, but i don´t know how to hardcode the game. I can do the drag ecuations and a estimated ecuation for lift.
I´m talking about 2.5 release.
