altitude for flight trimming - approx. 100' or so.  The transmitter trim
levers  are  then  used  to  trim  the  model  to  fly  straight  and  level.
Depending  upon  the  altitude  of  your  flying  field,  the  condition  of
your  flight  battery,  and  other  factors,  you  will  most  likely  find  that
the KADET EP-42B will fly well in level flight at 1/2 to 3/4-throttle
setting.    This  reduced  throttle  setting  will  slow  the  model  down,
increase your flight duration, and make the model easier to fly for
beginners.  Note that every time the throttle setting is changed, the
elevator trim must also be re-adjusted to make the model fly level.

The  KADET  EP-42B  has  very  mild  stall  characteristics  -  straight
ahead with a slight nose drop, resuming flight almost immediately.
It can also be banked fairly sharply with little tendency to "fall off".

Landing the KADET EP-42B is relatively easy.  The power-off glide
is quite flat and all flight controls remain effective at slow landing
approach speeds.  Flying into the wind, line up with the center of
the  runway  and  gradually  throttle  back.    As  the  airplane  slows
down, the nose will drop, allowing the airplane to glide down to the
runway.  If the glide is too steep and the model is picking up speed,
feed in a little up elevator until you get a shallow glide at a constant
speed.    About  a  foot  or  so  above  the  ground,  start  to  flare  the 
landing by carefully feeding in more up elevator a little bit at a time.
This will bring the nose up, slowing the airplane even more.  Try to
hold  the  airplane  just  inches  off  the  ground  until  it  finally  slows
enough to settle smoothly onto the runway.

Caution:

Never land your airplane in tall grass or weeds with the

motor running.  Always throttle back completely if you land in such
terrain or if you nose over after landing.  Tall grass or a nose over
will stall the motor if it is running.  A stalled motor can overheat the
ESC and batteries, causing them to fail.

JOIN THE CLUB

Although the KADET EP-42B is considered a "park flyer" and can
be flown in fairly confined spaces by accomplished pilots, it should
never be flown within five miles of an organized R/C aircraft flying
site.  This one simple precaution can prevent the loss of your model
from radio interference.  Do yourself a favor and join your local R/C
club - you'll almost always get assistance and good advice - and
you will even make a friend or two!

GOOD LUCK AND HAPPY LANDINGS!

in  order  for  the  model  to  fly  "hands-off"  straight  and  level.    An 
experienced pilot can instantly correct out of trim conditions before
the model crashes into the ground.  An inexperienced beginner has
almost no chance of saving an out of trim model!

The second reason for an instructor is to have someone there to
correct the mistakes you will make during the learning process.  It
isn't that flying an R/C model aircraft is all that difficult.  It is more
a matter of learning what to do and when to do it.  No matter how
slowly a model flies, an incorrect control input can produce almost
instant  problems  that,  in  turn,  demand  almost  instant  correction.
This  is  especially  true  at  lower  flight  altitudes.    A  good  flight 
instructor will climb your model to an altitude that gives him a good
chance  of  saving  your  airplane  when  you  make  these  inevitable
mistakes.    This  altitude  is  generally  referred  to  as  "2  mistakes
high".  When you get into trouble, quickly hand the transmitter back
to  your  instructor  so  he  can  rescue  the  airplane.    He  will  get  it 
leveled off, and then, let you try it again.  Without an instructor, it is
very likely that you would not receive this second chance.

Beginning  R/C  pilots,  almost  always,  over-control  their  models.
This  is  perfectly  normal  but  a  trait  that  must  be  cured 
during  instruction.    Another  problem  common  to  beginners  is 
disorientation.  For example, when the airplane is flying away from
you, right aileron input produces a right turn and left aileron input
produces a left turn.  However, when the airplane is flying directly
toward  you,  the  same  right  aileron  input  now  makes  the  airplane
turn to YOUR left.  The airplane is still turning to it's right, but that
is  now  your  left  side!    This  perceived  control  reversal  is  very 
confusing to all first time R/C pilots!  Without an experienced flight
instructor on hand, it will most likely cause the loss of the model.

With  a  flight  instructor,  these  early  learning  problems  can  be 
easily dealt with.  The more you fly, the quicker you will learn.  Soon
you will be flying "solo" with little thought of the moves required.  It
will start to come easy.  Remember the first time you tried to ride a
bicycle?    It  seemed  completely  awkward  the  first  time,  but  once
you  learned  how,  it  became  easy.    Don't  get  discouraged  if  you
have a minor crack-up.  Repair the damage and get back into the
air as soon as possible.

FIRST TEST FLIGHT:

Choose a calm day, with little or no wind, for the initial test flights.
This is important in getting the model properly trimmed.  If there is
too much wind, you won't get a true reading on what the model is
doing in the air.

The  KADET  EP-42B  is  capable  of  taking  off  from  any  smooth 
surface runway or a closely cut grass field - this is called an ROG
(Rise-Off-Ground)  take-off.    The  correct  ROG  take-off  procedure 
is  to  line  the  airplane  up  with  the  center  of  the  runway,  facing 
directly  into  the  wind.    Advance  the  throttle  smoothly  to  full  high
throttle  position.    As  the  airplane  accelerates,  apply  a  little  right
rudder  input  to  counteract  motor  torque  and  keep  the  model 
tracking straight.  When sufficient speed is attained, a small input
of up elevator will get the model airborne.

The KADET EP-42B can also be easily hand-launched if the grass
is too long at your flying field.  When hand launching, the airplane
must be launched, straight and level directly into the wind, with the
nose  aimed  at  a  point  on  the  ground  about  75'  in  front  of  you.
Never  launch  the  model  with  the  nose  pointed  up  or  the  wings
tipped to one side or the other.  The launch should be firm enough
to achieve flight speed, but yet, not overly hard.

Once the airplane is in the air, it should be flown to a reasonable
