F1A launch style

2.. Is it better to launch straight or to try to bank & turn during
the bunt? My inclination is to launch straight without any turn during
the bunt sequence, eliminating zoom rudder deflection and taking out
wing wash-in (so there will be no transition from dragging to lifting on
the washed in wing) during the acceleration ( hook straight, latch open
phase). I am hoping this will reduce the need to keep one eye on the
model whilst the desperate sprint phase is on at the bottom end of the
line (and streamline the model for a bit more speed as well?) Can’t
imagine having to hang on till the model turns in the right direction
whilst covering ground like a greyhound would be a reliable way to go.

2. It is much easier to launch straight, although most launches are a
curve or arc to a greater or lesser degree. It is possible to build up
lots of speed by setting the model to curve when unlatched such that the
acceleration starts when the model is actually pointing away or is
perpendicular to the direction of the running. The model then has to
make a turn during your run such it is pointing forward and is high on
the line at the moment of launch. I have done this but have found it to
be very tricky and hard to repeat is changing weather conditions. If
the conditions were always calm it would be good, but mix in wind and
the timing and settings need to change, but you don’t need the extra
speed in wind anyway so better to stick with the more forgiving straight
setup. In reality I like just a slight amount of turn or arc such that
the acceleration can start just when the model is “turning the corner”
before the launch.

A little turn is good if it is windy and thermally but you must not have too
much. A bunt is less critical of launch attitude than a zoom but if the
model is turning too much it will roll level and bunt down.
