A fuel tank in the nose of the airplane? Come on. Its probably what I'll have to do. I forget who makes them, maybe its sulivan, but its called a flex tank. I used one in my 4*40 to get the biggest tank I could in it. It worked very well, even made getting the cap in a bit easier. The senior seemed to run well, but never more than a acceptable idle. Its a Saito .72. I just liked the idea of long flight times to make it easier to both work with my son and get some stick time myself. Another issue with the tank size was the room in the nose, it gets hard to get the fuel tank cap at the right height for the motor position.
