From The AMA Control line general rules.
You will notice that the Safety Thong is required for ALL control line events except Racing events.
4. Safety Thongs. A safety thong
connecting the handle of the Control
Line models to the pilot’s wrist, and
strong enough to prevent accidental
release of the model, shall be worn
during all flights of Control Line events
except all Racing events. The safety
thong should have a minimum amount of
slack to preclude accidental release or
interfering with the controls. Releasing
the controls during flight or before the
model has come to a complete stop shall
constitute a foul if the safety thong
restrains the model and lines from flying
free; if the contestant releases the
controls and the safety thong during
flight or before the model has come to a
complete stop, the contestant shall be
barred from further participation in the
event and all of his previous flights
canceled. In those events not requiring
the use of a safety thong, releasing the
controls during flight or before the
model has come to a complete stop shall
bar the contestant from further
participation in the event and void his
previous flights in the event. The safety
thong may be a point of attachment for
conducting the pull test or the thong may
be tested separately from the test of
control handle, lines, and control
mechanism. When the thong is tested
separately, it must be pulled to the test
load specified for the particular model
involved. The method of thong
attachment shall also be able to
withstand the required pull test. Failure
to use a safety thong in those events for
which they are required shall constitute a
foul. Although safety thongs are optional
in Racing events, their use is encouraged
in all events, particularly when Junior
and/or Senior fliers are involved.
