HI All,

A quick test for this is to fly into a 45 degree upline and perform high-rate aileron rolls to one direction. You will quickly see if the plane arcs off one direction or the other - or maybe rolls on a string (lucky). Repeat this in the opposite direction. I think continous rolls are needed versus 1 roll to really see the tendancy.

After adjusting the differenctial so that the plane will do continous aileron rolls on a 45 deg upline, the normal rolling elements are now perfomed easier. Prior to fixing this, it was a tad more difficult to maintain baseline and heading during rolls. After this, it is easier (4/8 opposite slow, & 3/4 opp slow rolls for example).
