<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></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></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
references. And the same things apply</FONT></DIV>

<DIV><FONT face=Arial size=2>All my models have them boxed and will have them
boxed in.</FONT></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
meet.</FONT></DIV></BLOCKQUOTE></BODY></HTML>
