Hi all, Not getting much time to devote to my A7 at the moment.
However, have decided it's more trouble than it's worth to cut throught the wing to let the fuel tank through, so it'll will go as far back as it can and be left hanging out in the cockpit.

However, my next problem has arrisen. The outlet duct in the A7 is 3.75" and my Kress fan is 4" and i can't get one to fit in the other.

Can anyone suggest anything?
