The earlier Big Hawk models have different fuel tanks. Maybe yours is an early one and those were bigger

The mod was made, to allow to install turbine in a forward position and avoid adding too much nose weight

Compare the one in my previosly pic and the ones I have attached from another plane: Maybe Del Gato is an early one as well, if you fly 7min. Can you or Anton can make a comment why was this mod made, but I don't feel comfortable with only one of these tanks using a P160.

Last pic shows a New fuel tank and intake mod with a second fuel tank that SM says it is not available (don't seem to affect CG that much. Seems the better setup, but where to find this tank??????
