This exercise was easily the most effective single thing any
instructor had me do during my student pilot days. It does more than
teach you how to use the stick -- it teaches you how to react, and
after that day I found my final approaches to be much easier, not just
the take-offs. This should be a mandatory exercise for students when
the opportunity presents.

Bill Daniels' suggestions are excellent. Also - note that wing drop
(especially with some tow planes) can be more likely on a no crosswind
day - because the prop wash swirl is coming right back at the glider
instead of being swept aside.

I have found that the problem is most pronounced with mid wing gliders,
short tow ropes, and trike gear towplanes.

Don't worry about the use of the wrong control input. As a CFI I have
also seen that with new pilots and it will go way with time in the
aircraft. It takes time for your brain to process problem recognition,
correct response, and avoid over response. That process speeds up with
experience.

Concur that the best thing to do is to go balance your wings in a good
wind and build up muscle memory.

I have also seen it in a couple of students - my guess is that it might
be a "primacy" effect. We are used to walking with opposing movement of
our arms. When we are in a walking speed situation and the brain is a
little overloaded we tend to revert to left foot right arm. Hence at low
speed on the ground run suddenly the co-ordination fails.

Just a theory.

At our club those who have this tendency are encouraged to walk Left
arm/left foot to the glider when they are going to fly. Whether it is
the unconscious conditioning or the embarrassment they seem to have very
few repeat problems...
