We haven't used the zip starts that Bruce describes for a couple of years due to the
emergence of disk launch and the difficulty of achieving reasonable equivalence
between a
zip start and disk launch. To match a good disk launch, you almost need an upstart
which
is so long .
If the HLG
Soaring League of North Texas (SLNT) puts a length of string
or monofilament inside the surgical tube that limits how far you can stretch
the hi-start thus making the energy and resultant launch height fairly close to
what the DLGs boys can get. Yep, the zip start guys are anchored in
tangled in it on the ground are also problems we have
seen.As a result, the zip starts have fallen into disuse.
