<DIV>Now John may be on to something here....3 servos driving each
aileron on a pattern plane. HMMMMM!!!</DIV>
<DIV> </DIV>
<DIV>If helical is what you want, cut the aileron 3 ways, proportional areas
in each segment of course and drive it with Johns 3 preprogrammed servos.
And you can use the smallest, fastest servos around so your response will be
outasight. That's the ticket laddie, Ahuh....</DIV>

<DIV><FONT face=Arial size=2>For cryin' out loud, if your going to go to
all that trouble, use two servos per panel at the opposing extremes of
each flexible aileron driving in opposite directions. Now that's HELICAL
!!!!!!!!!!!!!!! What the heck have you guys been smokin'
?????????????? And I thought I was extreme. Are we in the "Twilight
Zone" here? BGw?</FONT></DIV>

<DIV><FONT face=Arial size=2>Helical pitch ailerons! Nat, this is
brilliant. Instead of making stiff ailerons, make them to
flex. glue the tip to the wing tip and drive the root end.
Ailerons would work just like a 74x6 propeller.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hey Tom</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm not providing solutions - just
putt'in more wood on the fire. In steady state roll the least drag
position of the ailerons would be constant AOA root to tip. This would
call for the percentage of chord to progress linearly so that it would
be double at the tip vs the mid span position - no different than
helical pitch. </FONT><FONT face=Arial size=2>A ( severe ?) negative
would occur, though, when the ailerons are initiated, potentially
causing a tip stall.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Martin Simmons provides a curve showing
Cl vs % of chord for the aileron. Going over 20% doesen't get you
much for the dollar - just much more servo wear and tear ( especially
with the 160 <G> ).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>IMO it is not worth the extra work to
stop the ailerons short of the
tip.
