6.1.13 Cut the ribs (21) from the pre-stamped balsa sheet and fix them to the plan with two drops of glue (Sk6) 

    Note:  

The spots of glue will be removed later. The roundest part of the rib faces forward.

6.1.14 Cut and remove a strip of sellotape from the underside of the wing aprox 5mm left and right of each rib 

(Sk5), otherwise the glue will not stick at a later stage.

 

 

Note: 

  Diagram 5 shows the left hand wing viewed from underneath!!!

6.1.15  Bend  the  right  hand  wing  half  over  the  wing  ribs,  press  the  leading  edge  down  and  pin  it  firmly  to  the     

board (set the pins in at an angle Sk6) DO NOT GLUE -remove the wing again but leave the pins in positi-

on.

    Note:  

Ensure the cut bending lines are underneath!

6.1.16 Apply glue to the top of each rib 

    Note:  

The glue must not run otherwise it will stick to the plans

6.1.17 Re-position the wing over the glued ribs with the leading edge tucked under the pin heads. Bend the wing 

and anchor the trailing edge to the plan in the same way. Both the leading and trailing edges must lay flat on 

the board. Leave to dry for approx 5 hours.
