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>

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>

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>
