Important: before you start construction 

Even  if  you  have  already  built  many  RC  model  aircraft,  please  read  right  through  these 
instructions  very  carefully,  and  check  that  all  the  parts  of  the  kit  are  present.  We  have 
taken  great  trouble  to  keep  the  building  effort  required  to  an  absolute  minimum,  without 
allowing any compromises in the area of safety. 
 
This model is highly pre-fabricated and can be built in a very short time. However, the work 
which you have to carry out is important and must be done carefully. The model will only 
be  strong  and  fly  well  if  you  complete  your  tasks  competently.  Please  work  slowly  and 
accurately! 
 

Note regarding the film covering 

Minor  creases  or  bubbles  may  develop  in  the  film  covering  due  to  major  fluctuations  in 
weather conditions (temperature, humidity etc.); in rare cases you may even find a slight 
warp in a component. These minor faults are in the nature of film-covered built-up wooden 
structures, and can easily be corrected using a heat gun, as commonly used for modelling. 
 
Creases: 

Blow warm air over the area and rub down with a soft cloth. 

Wing warp: 

Hold  the  panel  twisted  gently  in  the  opposite  direction  to  the  warp,  and 
apply warm air to remove the creases from the covering. 

 

Caution! do not heat the film more than is absolutely necessary. If the air or the iron 
is too hot, the film may melt and holes may be formed. 
 
When self-tapping screws have to be screwed into wood, apply a little white glue to 
prevent them shaking loose: just squirt white glue into the hole and fit the screw. 

 
 

Operating the E-TRAINER 140 
Before  you  attempt  to  operate  the  model  it  is  essential  to  read  right  through  the 
assembly  and  operating  instructions  very  carefully.  You  alone  are  responsible  for 
the  safe  operation  of  your  radio-controlled  model.  Young  persons  under  fourteen 
years  of  age  should  only  be  permitted  to  operate  this  model  under  the  instruction 
and supervision of an adult who is aware of the hazards involved in this activity. 
Please keep these operating instructions in a safe place. If you ever dispose of the 
model,  be  sure  to  pass  them  on  to  the  new  owner.  If  you  have  any  questions 
regarding the safe operation of your RC model aeroplane, please turn to your local 
model shop in the first instance, where the staff will be pleased to help you. 
 
Radio-controlled  model  aircraft  are  very  demanding  and  potentially  dangerous 
objects. As such they require a high level of technical knowledge and skill, together 
with a responsible approach. 
 
In  legal  terms  our  models  are  classed  as  aircraft,  and  as  such  are  subject  to  legal 
regulations 

and 

restrictions 

which 

must 

be 

observed. 

Our 

brochure 

“Modellflugrecht,  Paragrafen  und  mehr”  (Model  Aviation  Law,  Legal  Requirements 
and more) is available under Order No. 8034.01, and contains a summary of all these 
rules. Your local model shop should have a copy which you can read. There are also 
Post  Office  regulations  concerning  your  radio  control  system,  and  these  must  be 
observed at all times. Refer to your RC system instructions for more details.
