Default poor lateral control on a slow tow?

Wrong.

The correct term is

L=W in STRAIGHT flight.

If both forces are not equal, the resulting flightpath is going to be
a circular arc.

It's simple vector addition.

Well to get anal......straight and level.....(unaccelerated flight.)

Also best to consider L+W+T+D=0 (Unaccelerated flight, climb, level
or gliding)

Once we have acceleration (change is velocity and or change in speed)
then L+W+T+D do not =0 We now have "unbalanced" force(s)
