Do not switch on the electric motor unless you are sure that there is nothing in the 
rotational  plane  of  the  propeller.  Never  attempt  to  stop  the  spinning  propeller. 
Electric motors with the propeller attached should only be run when firmly mounted. 
 
If  you  are  to  fly  your  model  safely  and  avoid  problems,  it  is  essential  that  you  are 
aware  of  its  position  and  attitude  throughout  each  flight  -  so  don’t  let  it  fly  too  far 
away!  If  you  detect  a  control  problem  or  interference  during  a  flight,  immediately 
land the model to prevent a potential accident. Models must always give way to full-
size  aircraft.  Take-off  and  landing  strips  should  be  kept  free  of  people  and  other 
obstacles. 
 
Your RC system can only work reliably if the batteries are kept fully charged. 
Never  use  batteries  which  are  hot,  faulty  or  damaged.  At  all  times  heed  the 
instructions provided by the battery manufacturer. 
 
Before  each  flight  check  that  all  functions  on  the  model  aircraft  are  working 
correctly,  and  that  the  radio  control  system  is  in  good  order  and  operating  at  full 
range. Note that the motor control (throttle) function on the transmitter must always 
be moved to the OFF position as the first stage in preparing for a flight. To avoid the 
danger  of  the  electric  motor  bursting  into  life  unexpectedly,  always  switch  on  the 
transmitter first, and only then the receiving system. The opposite applies at the end 
of a flight: always switch off the receiving system first, and finally the transmitter. 
Check that the control surfaces follow the movement of the transmitter sticks: 
When you move the aileron stick to the right, the right aileron should deflect up, the 
left  aileron  down.  Move  the  rudder  stick to  the  right,  and  the rudder  must  move  to 
the right. 
 
Pull the elevator stick back towards you, and the elevator should deflect up. 
 
Move  the  transmitter  controls  smoothly  at  all  times;  don’t  jerk  the  sticks  about 
abruptly when the model is in the air. 
 
Please don’t misunderstand the purpose of these notes. We only want to make you 
aware  of  the  many  dangers  and  hazards  which  can  arise  if  you work  carelessly  or 
irresponsibly.  If  you  take  reasonable  care,  model  flying  is  a  highly  creative, 
instructive, enjoyable and relaxing pastime. 
 
Notes on building and flying the E-TRAINER 140 
Before you start construction:

 

If  you  are  buying  a  radio  control  system  for  your  new  model,  ensure  that  the  transmitter 
and  receiving  system  are  expressly  stated  to  be  suitable  for  use  in 

model  aircraft

,  and 

bear the appropriate approval stickers. 
 
The  frequency  bands  used  for  the  radio  control  of  models  are  also  employed  by  other 
radio  transmitting  and  RF  equipment.  For  this  reason  it  is  not  possible  to  be  completely 
sure that no interference will occur when you are flying your model. 
 
No licence fee is payable for using approved RC equipment to control a model aircraft on 
the appropriate channels in the 35 MHz band.
