Caution: This model is not a toy! 
If you do not have experience with such motorised models, please ask experienced 
model flyers for help. If the model is operated without the proper knowledge, injuries 
can result. Think of your health and safety. 
 
Important! Before you start the assembly! 
Even  if  you  have  already  built  lots  of  RC  models,  read  these  instructions  through 
carefully and check the parts in the kit for completeness. A lot of effort was made to 
keep things as simple as possible without neglecting safety. 
 
Note on the covering sheet 
Because  of  strong  changes  in  the  weather  (temperature,  humidity,  et  cetera),  small 
creases can form in the covering sheet. In rare cases, the components can even be 
warped. This lies in the nature of wood construction with covering sheet. This can be 
corrected as follows using a hair dryer like those available to model builders. 
Creases: 

Blow with hot air and rub with a soft cloth. 

Warped area: 

Gently twist the area against the direction of warping and smooth 
it out again using hot air. 

 
Caution! Never use more heat than is absolutely necessary. If the iron is too hot, the 
covering sheet will melt and holes will form. 
 
The extensively pre-fabricated model can be built in a very short time. However, the 
remaining steps are important and have to be carried out with care. Doing this work 
properly  determines  whether  the  model  will  have  the  prescribed  rigidity  and  flight 
characteristics; so please work slowly and precisely! 
 
When  putting  screws  into  wood,  secure  them  against  loosening  by  using 
casein glue: Squirt casein glue into the drill hole and screw in the screw.
