I have been interested in how much extra speed I can get out of my = Legacy using gap seals and other similar aerodynamic = =E2=80=9Ctricks=E2=80=9D.

 

Today I ran the plane in the =E2=80=9CBefore=E2=80=9D = condition.=C2=A0 Tomorrow, I intend to put on gap seals and change out = my cowl rings to a more aerodynamic pair.

 

Here is today=E2=80=99s result:
