I have problem. I correct the aileron the wrong way at takeoff

Because of the gyroscoptic precession of that big, heavy front wheel, this
tilts the bike, and it is the tilt that does the actual turning.

Humm. Bike going forward. Rotation vector of front wheel goes right to
left (using right-handed axis system). Push left handlebar forwards.
Front of rotation vector moves forwards. Precession vector is change
in rotation vector: front to back. Which is a roll to the right.

In other words, the affect of precession would roll in the direction
of steer.

A useful rethink is to consider that the wing runners job is to
BALANCE the glider laterally not to just "level the wings". *That way
the wing won't instantly fall when it's released. * The runner should
find the 'zero force' point where the glider is perfectly balanced
into any crosswind and run the wing at that angle.

The pilot should let the wing runner do his job by holding the
ailerons exactly neutral until it's clear the runner is no longer
holding the wing - usually at "three Mississippi" and only then take
over roll control.

I think these two points are in contradiction. If the wing would fall
when released unless the pilot did something, it wasn't balanced.

As a wing runner I respond to any wing tip forces. Pre-take off, if my
tip is pushing down, I will let it go down, to the ground of
necessary, till the pilot uses aileron to cancel the forces, at which
point I will keep the wings (a) level and (b) balanced.

I expect the same when I'm the pilot.

This is particularly important when winch launching, as the pilot will
experience any unbalanced roll forces within a second or three of the
all out, and have very little time to correct.
