MOUNTING THE PROPELLER AND SPINNER:

❑

36) For this step you will need the propeller and rubber spinner

from the kit contents.

a) Remove the forward 3.5 mm lock nut and the washer from 

the motor shaft.  Slide the propeller in place onto the motor 
shaft  with  the  center  hex  relief  facing  back  to  the  motor.   
Press the propeller in place over the rear hex nut.  Place the 
10 mm washer onto the shaft and then thread the forward 
3.5 mm lock nut in place against the washer and propeller.  
Tighten the nut securely.

b) The  rubber  safety  spinner  can  now  be  pressed  firmly  in 

place onto the motor shaft and propeller.

DECAL APPLICATION:

The  decals  supplied  with  the  KADET  EP-42B  are  Mylar

®

stickers

with a self-stick adhesive.  They are not water slide decals.  Also,
these  decals  are  not  die-cut.    Each  design  must  be  cut  from  the

movement.    Now,  make  sure  the  motor  shaft  is  moving  in 
the correct direction.  When viewing the fuselage from the 
rear to the front - as if you were sitting in the cockpit - the 
motor shaft should turn clockwise, when throttle is applied.  
If your motor is turning in the wrong direction, you have the 
polarity  of  the  motor-to-ESC  or  ESC-to-battery  wiring 
reversed.

CONTROL THROWS:

❑

34) The maximum distance that a control surface moves when

you move the transmitter stick to full deflection is normally called
the "control throw" or "control travel".  Most modern radio systems
allow you to adjust the control throw of the servos directly from the
transmitter.  This radio feature is usually referred to as EPA or End
Point Adjustment.  Use this feature to adjust the control movements
for the ailerons, elevator, and rudder of your KADET EP-42B.  The
following  control  movements  are  recommended  for  your  initial
flights.

RECOMMENDED INITIAL CONTROL THROWS

Ailerons: 5/16" (7.9 mm) Up 

5/16" (7.9 mm) Down

Elevator: 7/16" (11.1 mm) Up  

7/16" (11.1 mm) Down

Rudder:

5/8" (15.8 mm) Right   5/8" (15.8 mm) Left

NOTE:

These measurements are always taken at the widest part

of the control surface, at their trailing edges.

MOUNTING THE COWL:

❑

35) From the kit contents, locate the plastic cowl and the four

remaining T2 x 6 mm PWA screws.  Note that the correct mounting
location  and  position  of  the  cowl  is  with  its  forward  face 
approximately 1/4" (6 mm) behind the front face of the 3.5 mm lock
nut and centered with the motor.

a) Slide the cowl in place over the motor and onto the front of 

the  fuselage.    Use  pieces  of  tape  to  secure  the  cowl  in 
place,  centered  with  the  motor  -  do  not  cover  the  four 
pre-drilled mounting holes.  The front of the cowl should be 
about 1/4" (6 mm) behind the front face of the 3.5 mm lock 
nut on the motor shaft.

b) Use a sharp pencil or a pointed object, such as an awl, to 

mark  or  punch  a  centered  mark  in  one  of  the  cowl 
mounting  hole.    Use  a  small  (.040")  dia.  bit  to  drill  a  pilot 
hole through the fuselage side at the mark just made.  Use 
a  screwdriver  to  install  one  of  the  T2  x  6  mm  PWA  cowl 
mounting screws into the drilled hole.  Check the front of the 
cowl to make sure it is still centered, and again, use a sharp 
object to mark the center of the opposite hole in the cowl.  
Drill a pilot hole and install another mounting screw.  Repeat 
this process until all four mounting screws are in place.

SAFETY WARNING:

With the propeller mounted to the motor,

it  is  very  important  that  you 

always

remain  aware  of  the 

position of the throttle stick on your transmitter whenever there
is a battery plugged into the airborne system.  The motor unit
used  in  this  model  is  powerful  enough  to  cause  damage  to 
people or property if it is activated prematurely, accidentally, or 
unexpectedly.    With  an  electric  airplane,  we  recommend  that
you  get  in  the  habit  of  always  keeping  the  throttle  stick  in  the
"low throttle" position, even when the transmitter is in storage.
Be  sure  to  recheck  the  throttle  stick  position  before  plugging 
in  the  airborne  battery  pack  and  also  before  turning  on  the 
airborne  on/off  switch.    Under  no  circumstances  should  you
hold  this  model  by  the  nose  when  the  battery  is  plugged 
in.   

Never

plug  your  flight  battery  to  the  ESC  until  1)  your 

transmitter is on with the throttle stick in the low position and 2)
you are on the flight line, ready to fly.
