Excess Aileron sensitivity around neutral

[Del K. Rykert]

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...

  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..

    Eric, 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 load.

    Jim Ivey,  Aileron deflections are 15 degrees low rate 18 degrees high rate.

    Del and Amir, The trailing edge of the ailerons is sharply rounded.  The TE is 1/8 " width at the end and has a 1/16" radius.
