top of the slope and "slide" into the top of the
slope without encountering any turbulent air.
On steeper slopes you may have to be a little
more aggressive to get the plane out of the lift.
In any case it is a good idea to plan your landing
before you launch your plane.
In strong wind conditions, you may want to add
ballast (weight) to the sailplane to increase its
wing loading which increases its normal flying
speed. Increasing the weight of your sailplane
does not change its "glide ratio" but it does
make it fly faster which makes it sink a
proportional amount faster. Because of this
faster sink rate, you need to be very cautious
when ballasting for a thermal contest. In
duration type contests only use ballast on very
windy days that also have a lot of thermal
activity.
Add the weight as near as possible to the C.G.
of the plane. 4-8 oz. will make a noticeable
difference in the sailplane's flying speed and
more can be added if needed. Make sure to
recheck the C.G. of the plane after adding
ballast - it should remain where it was.
Have a ball! But always stay in control and
fly in a safe manner.
GOOD LUCK AND GREAT SOARING!

• Compact power for high-altitude launches.
• Complete systems for 2-meter and unlimited class
sailplanes.
A Dynaflite Hi-Start and 800' of clear launch area are
all you need to send your sailplane rocketing up to
500' in the air! Easy to lay out and retrieve, Hi-Starts
include everything required for sailplane launches:
100' of UV-stabilized surgical tubing, injection-
molded reel, parachute, steel stake and tow ring, and
nylon tow line. Standard Hi-Start with 1/8" diameter
tubing offers strong, steady power for 2-meter
sailplanes. Heavy-Duty Hi-Start with 3/16" diameter
tubing provides the launch power needed for
sailplanes spanning 100" or more.
