What I was trying to say in the clearest way that I can put it is if you are not familiar with a given type and ( for instance) don't even know where the fuel tank is, or have never even sat in one let alone flown one then I don't think you are qualified to speculate.
So I take it those of us who have can continue to speculate?
Not that sitting in the front of one for what was a very memorable flight avails me of any great knowledge of the type but it was quite fun and I figured out the fuel tank position. No doubt as I continue to move backwards through aircraft evolution in my own flying PA-28 to PA-18 to DHC-1 ... it's only a matter of time before I get to fly a Tiger Moth as PIC too, so please speculate away guys for those of us who may benefit and are certainly not posting to win silly points, but because one day it really may be important information.
And hatzflyer, though you may be very knowledgeable you don't come across as particularly open. Fortunately the moth pilot who will no doubt teach me is far more down to earth about the realities of flying older aircraft.
