Tim, I will pay attention to the way it affects the handleing. I have used them many years ago, but it was too much weight for the 447.
Stan, you should see my smile with that 503 ! Now without the constant fuel watch going on & radio & GPS......I am gonna really be livin' !!!
Stan, do you remember how you used those tanks? ( factory piping?, Burn aux tanks first? ETC ....... )
