Thank ya'll for your deep insight and perception on flaps.

I have Hangar 9's P51 Mustang PTS which comes with fixed flaps. Either you can push them down to the last position so they would stay same at all times like fixed. That is the purpose of training as it was designed as a trainer. But I have been flying planes for the last 5 years and I think I'm beyond training flyer. I never used those flaps when I first got my Mustang PTS, now it's my second Mustang MKII so I don't use these flaps either. I was told by a flyer back in my home town that this flap would cause your plane fly with a nose up and he is a very senior flyer and back in 2005 I did not believe him then, and don't believe him now. Main purpose of fixed flaps to the down position is to make this plane fly slow, but as I did not use it before, I m not gonna use it now. I have been interested in flaps, but never used it and in near future I don't have any plane which may have flaps. Flaps I have left it to the future.
