Fuselage Continued

17.

Fit and bond part F15 to the fuselage sides, over the third set of tabs 

forward

 from the 

rear

 

of the fuselage.

18.

Fit and bond the center stringer F16 to the 

center

 slots in formers F3, F13, and part F15.  

19.

Fit and bond stringers F17 to the next set of slots out from the 

center

 stringer F16.

20.

Fit and bond stringers F18 to the 

outermost

 set of slots in formers F3, F13, and part F15.

21.

Fit  and bond  a 

right

 and 

left

  part F19 to  the  notches  in the 

right

 and 

left

  fuselage sides 

immediately 

behind

 former F3, resting on stringers F18.  

Tip:  This a very tiny part, somewhat difficult to handle.  Pick up part F19 by lightly poking it 

on  the  tip  of  your  hobby  knife.    Apply  a  small drop  of  medium  CA  to  the  notch  in  the 

fuselage  side,  and another  drop on  the  underside of  the  stringer  above.    Fit  part F19  in 

place and set the CA with a shot of accelerator.  You should now be able to pull the hobby 

knife out, leaving F19 placed perfectly.  Please note that F19 will not make contact with any 

part of former F3 - the gap between F3 and F19 is intentional.

22.

Fit  and  bond  the  bottom  sheeting  F20 

between

  the  fuselage  sides, 

behind

  F6  and 

overlapping the bottom edge  of part F7.   Ensure that the slot  between  F7  and F5 is  not 

covered by F20 and the arrows etched to F2 face 

forward

.

23.

Fit  and  bond  bottom  sheeting  F21 

between

  the  fuselage  sides, 

between

  former  F2  and 

overlapping the 

bottom

  edge of part F5, overlapping part F5.  Note: The tabs  on F21 will not 

completely fill the slots  on F2.    This  is  to allow part F24 to fit in the same slots  at  a later 

step.   Ensure that the slot 

between

 F5 and F7 is not covered by F21.

24.

Fit and bond nose part F22 to the tabs at the 

front

 of the ply motor  mount assembly.   Note: 

Orient part so that the curved edge matches  the curve of former F2.  Attention! Tabs on F9 

and F10 will protrude slightly from the face of F22.
