just re-read your post.
Hmmm so the...
elevator and aileron stick controls go to the DL TX, then to the Rx,
PPM to the DOSD,
ELE and AIL from the DOSD PWM outputs into FY?
In menu mode (not autopilot) DOSD does not output ail and ele.
FY should therefore not be getting any control input change to pass to the servos.
There must be some channel assignments amiss methinks, or some mixing in your radio (eg dual aileron or a ail>rudder mix)
or aileron plugged into rudder socket on FY
