<DIV>I have done it both ways and notice virtually identical performance as long
as the aileron areas (as a percentage and planform) are unchanged. What I have
found stops the snap accurately and repeatably is a light wing. Have not
required servo pots in either type after 100's of flights. Don't know why some
are losing servos after a few flights, but do know what works for me.</DIV>

<DIV>Commercial jets flying at 600 mph and models flying at 100mph, don't have
much in common.</DIV>

<DIV><BR></DIV>Again, with the 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

<DIV><FONT face=Arial size=2>They don't fly the same....and the aileron
thru the tip thing wears out servo pots faster. I 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.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Wing tips have lots of turbulence coming off
of them...then stick a aileron in this turbulence. NOPE not the best from
an engineering standpoint. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>The answer guys and 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.</FONT></DIV>

No fixed tips?</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>No fixed tips at the end of the wing/stab
seems to be the rage. Any real reason for this? I really don't care for
this very much as it makes it harder to make sure your trim is right and
