Thank You for buying the model of Backfire F5F. Backfire F5F is a full-carbonic model, it is 

made by lamination into negative forms. Backfire F5F is suitable for the competitive league 

F5F

, F5B/7, and for the hobby flying as well. The model was designed for competitive flying 

and its design results from the latest innovation of the F5F category. The aerodynamic was 

created by the German expert Dirk Pflug.  

The  fuselage  is  full-carbonic  and  there  is  a  possibility  to  make  an  Aramid  or  a  glass 

fuselage as well, if the customer requests that. The wing is also full-carbonic and there is a 

carbon  cloth  93g/m

2

  with  an  orientation  of  ±45°  on  its  surface,  which  inhibits  from  wing-

twisting. The spar is made of UMS roving. The standard wing is made of one part, but there 

is a possibility to produce the three-part

2

 wing according to customer´s wish. The elevator  is 

made of glass with a carbon flap of the cloth 93g/m

.  

There is also a possibility to produce a model – version „Show“ for an extreme flying. Be 

very  cautious  while  flying  with  „Show“,  because  it  allows  to  reach  high  flying-speeds  you 

should avoid the situation when you could damage someone´s assets or hurt someone.

 It is necessary to use solid (one part) wing.

  The  three-part  wing  is  designed  for  the  hobby  (recreational)-flying.  It  is  necessary  to  take  into  account, 

that this wing does not reach the strenght of the one-part wing.
