<DIV><FONT face=Arial size=2>Myself I suspect the 1/16th trailing is
contributing some.. I remember a dirty bird I had that had paper thin
trailing edges and was very touchy to aileron till I replace aileron with new
ones that were 3/16th rounded.. settled down and much better around
neutral.. not as touchy and long before anyone had expo on radio let alone
programmable throws.. All had to be adjusted mechanically.. Grin...

<DIV>It looks like 15 or 18 degrees could be just too much. I would try
to go below 12 degrees for the high rate. In other worlds, I will reduce
the rates as much as practical keeping the D/R as close as possible to 100%
for the DR that you use for normal fly. (What is your DR values
now?) In any case getting better mechanical advantage is
easier to do and looks like have been the most common
recommendation.. </DIV>

<DIV><FONT face=Arial size=2>Eric,</FONT><FONT face=Arial size=2> Regarding
mechanical advantage, The radius on the servo arm is 15 mm, the aileron
control horn is 25 mm. The battery shows 5.2 volts under
