Oh man, clunks that move forward, twin clunks... this has become madness. Opjose... he's just trying to sound important, make this problem more than it is so don't for gods sake join in as the could well be somebody that'll accually do these things. As everyone is saying, we don't have the problem!
Maybe Opjose does, maybe thats why he's so keen to talk about big things, yet this isn't a big problem. Admit it, if you suffering it's because you're done something wrong bubba and thats a shame because folks have been tring to help you but you've gone and got that head suck so far up... you're critically close to turning yourself inside out.

Listen, if this was a major problem, people world wide would be having major problems. But they're not. So lets pretend that all of us ain't doing the "advanced" aerobatics that you do. Jez yes now you mention it, every plane I've seen performing aerobatics at competition... ran out of fuel during a down line! Including my own! Yikes, we all must be suffering from some form of delusion because I sware that the engines seemed to stay running!
Let me ask you, when your doing all this talking and acting like a pro... why are you having your fuel tank at the front like a amature?
Why not on the CG where most, if not all aerobatic boys have it? Make physics your practical answer instead of just talking about it.
Not as if it's necessary of course, folks don't seen to suffer from the problem anyway.
Where here to help you Opjose... just with draw your head and wash out your ears.
