<DIV><FONT face=Arial size=2> Oops, when I said the ailerons
were OK at full throttle I meant to describe that the aileron authority was not
excessive, not that the excessive sensitivity is speed or throttle related - it
is not. Sorry I was not more specific.</FONT></DIV>
<DIV><FONT face=Arial size=2> Some more details:</FONT></DIV>
<DIV><FONT face=Arial size=2>* Servos are two digital 9252s, should be
plenty of torque and have excellent resolution around neutral - no pot
problems.</FONT></DIV>
<DIV><FONT face=Arial size=2>* Linkage is carbon fiber rod and no
slop.</FONT></DIV>
<DIV><FONT face=Arial size=2>* Expo is - 45% to reduce the twich. ATV
is 100 % high rate 90% low 75% (normally high would be 100% but is dialed down
while working this problem).</FONT></DIV>
<DIV><FONT face=Arial size=2>* Airframe - no loose covering, clevis pin is over
hinge line at neutral, servo arm and control horn are 90 degrees at neutral
(control geometry). CG is rearward but not tail heavy - pitch is not
twichy. </FONT></DIV>
<DIV><FONT face=Arial size=2>* have not measured wing and stab
incidence angles.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>*** one thing that Del mentioned - Aileron trailing
edge (and wing) taper to a very sharp radius ~ 3/32 to 1/8 inch.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>

around neutral</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2> I have a Meridian with a
frustrating characteristic, the ailerons are excessively sensitive around
neutral.</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm the second owner of this plane but the first
owner said he had the same problem. Aileron authority at full throttle
is not excessive - in fact it slightly on the mild side.
</FONT></DIV>
<DIV><FONT face=Arial size=2>Any ideas ?</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
