full-size: Notice that such luminaries as Boeing, Douglas, et.al don't
run their ailerons to the tips, but instead stop short? As
Troy and Doug have stated, the wingtip vortices generated are the
reason. I had a long discussion with Dick Hanson about this, and he
stated that "it didn't make any difference on our models." Well, from
what Troy has discovered about aileron pots, it seems it DOES make a
difference.<BR>Bill Glaze<BR><BR>Troy A. Newman wrote:<BR

flew a model this past summer and it went thru aileron servo pots in 50
flights. I normally get well over 100-125 flights. And this was a wood model
so the vibration was better damped than a composite
fuse.</SPAN></FONT><o:p></o:p></P></DIV>

manufacturers give is it snaps better. My answer is design a good wing
and it will snap better. Copy a good wing and it will snap better. The
ailerons become more effective with the area at the tip....but I don't feel
it helps flight performance. Aileron thru the tip is much easier and
faster to build than a boxed in version. on the ARFy stuff its
cheaper...this is the biggest reason I think its
done.</SPAN></FONT><o:p></o:p></P></DIV>
