<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 wrote:<BR>

<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><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><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>

<DIV><FONT face=Arial size=2>As for elevators without tips there are no

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
the elev half's
