The tanks are all the same. its just we decided to mount the this way so that I the section behind the cockpit ( Above the inlets ) could be left free for the board with my switches and fill points. As well as keeping fuel lower in the fuselage. I pass this info onto to all our customers and give them the option of doing it this way. ( along with a few other changes and mods, most of which are on this thread by now )
