 I have precise speed brakes and have had unequal retraction multiple
 times very dynamic but can be offset with ailerons . I sent mine back
 they did the most recent upgrade said I was ok . Has happened once or
 twice since. This occurs in my plane after water saturation, they told
 me to enlarge my drain hole that water on them can cause problems, no
 help. Have problems if plane left out in rain, not so much wet ifr
 flying
