FIRST FLIGHT

veryeasy
to
fly, if you are a novice modeler/pilot,we highly
recommendthat
youseekthe helpof an experienced
modelerfor

When

to climb you pull the stick back

When

the throttlestickforward
and
when

youpull

theturning
that
causes
themost
problems
with novice
pilots
becausewhen the plane

this

is
to tryand
always
face

characteristics.Keepthemodelupwindandclimb

THERMALS
Thermalsoaringis one of the most interestingand
challengingtypesof flyingthereis. Believeit or not,
your

andcoveringdozensof
miles.Thefollowing
paragraphs
willhelpexplainhow
to take advantage
of natures energy sources
called
thermals.
"Thermal"

This air is rising because it is warmer than the
surroundingair.Adustdevilissimplya

Thermalsoccurwhen

Thermalsvaryin

thermalsare so strong
they
caneven
rip
a sailplane
apart,especiallyif the plane is flying
fast when it
passes
through
the
thermal.
THERMAL
SOARING
Ittakes
lots
of oractice
and concentrationto thermal
soar
likethe
HawksandEagles.Sincethe
pilot
is
not
sittinginside
an modelsailplane,he cannot
feel
the
thermal,
he
canonlysee
his
sailplane's
reaction
to
the
thermal.Therefore,themajorityofthetime,
unless
the
pilot
is paying
carefulattentionto the plane,
he may
not even realizethat plane is near a thermal. Since
mostthermals
arerelativelysmall,lessthana hundred
feetin diameternearthe ground,
the sailplanewill
rarely
fly directlyinto the thermaland start rising.
More likely,
it will fly near a thermaland the wing
closestto the
thermal
willrise
turning
the
plane
away
fromthethermal.Soas
you
cansee,aninexperienced
pilot
may bouncearoundbetween
the thermalswith
ever
knowing
thatheisencounteringrisingair.
In
order
to
takeadvantageofthermals,
you
need
tofly

as
few
control
inputs
as
possible.
Watch

Whena sailplanedoesfly
directly
intoathermalit
will
eitherstartrising
or stop sinkingat its normal
rate.
Either case is reason enough to explore further.
Continueflyingstraightaheaduntil
you
have
obviously
passed
throughthe area of strongest
lift. Now start
circling
infairly
tight,butsmoothcircles. Because
of
the thermalsinvertedfunnel shape, the lower the
planes
altitude,thetighter
the
circlesneedto be. As
the
plane
gains

the

can
be increased. lf youseethe plane
