<DIV><FONT face=Arial size=2> I think you have too much throw on the
ailerons.You should look for maximum of 12-15 degrees up and 12-15
degrees down as measured with a gage of some sort. Seal aileron
gap,also.</FONT></DIV>

<DIV><BR></DIV>
<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>

<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>
