Hangar 9 offers a Sailplane Launching System (SLS) called the
Hangar 9 G-Force. For your convenience, the SLS is completely
assembled. The components that make up this product are of the
highest quality and reliability. Used properly, this unit will offer
you many seasons of successful launches. Please read the fol-
lowing instructions to maximize the performance and life of your
Sailplane Launching System.
Launch Area
Your local AMA sanctioned flying field is the best location for
flying. However, if you do not have access to such a field, many
other open areas will work. Refer to Table 1 below for the
minimum launch area required for your particular SLS. To avoid
possible damage to your SLS and sailplane, be sure to choose
an area that is clear from brush, trees and other obstacles.
Preparation for Launch
Depending upon the layout of your flying field, you will need to
locate the furthest point upwind as possible. As you determine
your anchoring point, keep in mind that your SLS will unwind to
either 200 or 400 feet and will stretch an additional 150 or 300
feet, depending on which version you have purchased. Once
you’ve found a suitable anchoring location, find an area of
ground that’s reasonably firm. Place the metal ring that’s
attached to the rubber tubing around the 9” steel stake. At a 45
degree angle away from the launch area, drive the stake into the
ground. (Refer to diagram below.)
Pull hard on the tubing at the base of the stake to be certain it’s
secure. Once the stake is secure, unwind the rest of the tubing
and nylon line downwind toward the launch area. The hand reel
will conveniently lay out the SLS without any tangles or knots.
Now that the SLS in completely unwound, you’re ready to
launch your sailplane. Refer to Table 2 below for proper stretch
distances for your particular SLS and sailplane class.
Once you’ve determined the proper stretch length for your SLS,
walk the distance with the hand reel and sailplane. At the given
point of launch, leave the hand reel as a marker. Its bright
orange color makes it easy to locate and also makes it unneces-
sary to recount the stretch length for each launch.
Note: When stretching out your SLS, stretch it out by hand,
not while still attached to the sailplane tow hook.
Now that you have stretched the SLS to its appropriate length,
place the ring attached to the parachute over the tow hook. With
a firm grasp on the sailplane, angle the nose up at a 45 degree
angle into the wind. Making sure that the transmitter and receiv-
er battery are “on,” toss the sailplane into the wind. The SLS will
have enough power to pull it right out of your hand! During the
launch it may be necessary to track the sailplane straight using
the rudder. For your first launches elevator input should not be
necessary and is not recommended. Giving too much up eleva-
tor input can result in oscillations in the sailplane, which can
overstrain the wings.
