If you REALLY NEED the extra L/D for flying farther afield that MIGHT
be a slight reason to consider the Acro. Other than that replacing an
ASK13 with a trailerless Acro would probably be a bad move. Actually,
with no trailer available you would have to be even more conservative
and stay closer to the field with the Acro than the ASK13. The Acro
also hasn't been given the "plastic pig" nickname for nothing. Heavy
to fly, heavy to rig and, currently, not even aerobatic thank's to an
A.D.
