When I had a flapped Nimbus 2, I always set the flaps to zero for the
ground run and selected the first stage of positive once I was established
in the full climb. That way I could keep my hand on the release knob during
the ground run. The rapid acceleration of a winch launch gives you almost
instant control.

For aerotows I started in full negative and notched the flaps back as I
gained speed and control.

Good question.

When I had an ASW-20 I kept my hand on the release until the ailerons
bit, moved the flap lever to position 3 and put my hand back on the
release with minimum delay. I always assumed this was close to the
optimum, but was that a correct assumption?
