</FONT><FONT COLOR="#0000ff" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=2 PTSIZE=10 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> I have been avidly following the progress of the Wright Flyer replica. It's driving me nuts watching them try to fly it. (Is there an aeronautical engineer on the project? - looks a lot like pilots and carpenters)</FONT><FONT COLOR="#0000ff" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=3 PTSIZE=12 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

There's almost nothing up front to bring the CG to a decent stable point. Am I off base here?</FONT><FONT COLOR="#0000ff" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=3 PTSIZE=12 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

</FONT><FONT COLOR="#0000ff" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=2 PTSIZE=10 FAMILY="SANSSERIF" FACE="Arial" LANG="0">Also I have meddled with models of the plane a little. Wing warping that goes only goes down induces worse wash-in at the slowest of speeds and is pretty nasty in the model. Instead of lifting the wing it drags it back making the plane turn adversely to the intended input. I know that they were trying to fly an exact replica so they went with everything as true to history as possible, but it is frustrating watching it struggle.</FONT><FONT COLOR="#0000ff" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=3 PTSIZE=12 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>
