WING CONFIGURATION
The SPIRIT 100 kit has two different wing options
The SPORT wing uses the Selig 3010 airfoil, has
optional spoilers and is recommended for novice sailplane
pilots This wing is easy to build, easy to fly and offers
great all-around performance without requiring expen-
sive radio equipment The spoilers arc highly recom-
mended as they make it much easier to land in smaller
spaces or to lose altitude in a safe controlled manner
The ADVANCED wing utilizes the Selig Donovan
7037 airfoil along with flaps and ailerons to provide
incredible thermal soaring performance This wing is
designed to be built with polyhedral which has been
found to work great - enabling the Spirit 100 to thermal
very tightly in low level thermals "Straight wing"
enthusiasts can cut their own polyhedral braces to elimi-
nate the polyhedral if they desire Computer radios and
radios with mixing capabilities can be used to obtain
total camber control (the whole trailing edge will raise or
lower together) and CROW (the ailerons raise about 75
degrees and the flaps drop almost 90 degrees) The SD
7037 airfoil, combined with total camber control, gives
you a sailplane that has an incredible L/D, yet will really
slow down and float when the whole trailing edge is
dropped about 3/32 This feature enables the Spirit 100
to out thermal any other plane in its class
RUBBER BAND OR BOLT-ON WING
Parts are included to build cither a rubber band on
wing or a bolt-on wing held in place with four 1/4-20
nylon bolts
The rubber band on wing is easier to build and will
absorb hard landings better so we recommend it tor less
experienced builders
The bolt on wing offers less drag and more precise at-
tachment It is recommended for the advanced wing and
the serious contest flyer
