triangular strips to base of Fin and glue Fin to 
Tailplane ensuring it is perpendicular and 

square

. If, when glue has set, it is not quite 

perpendicular to the Tailplane then slice the 
triangular strip on the acute angle (leaning 
towards) side and insert a thin cardboard 
wedge to correct any inaccuracy. Superglue 
wedge in place.  

15. Glue Tailplane in place checking that it is both 

horizontal and the distances between hinge 
corners on tailplane to centre of F2 are equal. 

16.  Fit Rudder and Elevator servos. 
17.  Cut Mylar Hinges to size (12mm x 25mm). Trim 

corners to stop them digging in and roughen 
gluing surface with wet & Dry. 

18. Hinge Rudder and Elevator control surfaces. 

Do NOT glue until the model is covered.  

 

Building the Wings 

 

1. To protect the plan cover in either thin 

polythene or cling film. 

2.  Join front & back 1.5mm sheeting. Use metal 

straight edge to trim for a good joint. The 
sheeting has been Laser cut but may require 
further trimming due moisture changes in the 
wood. Sellotape them together along the joint. 
Hinge joint back and insert PVA glue. Place on 
flat surface and wipe away excess glue. Run 
Sellotape along top of joint. Weight down until 
glue set. Repeat for other three pieces. 

3.  Accurately align bottom sheet on plan and pin 

to plan. Note rear of sheet overhangs rear spar 
by 1.5mm. 

4. Accurately mark position of mainspar on 

bottom sheet and using a straight edge glue 
and pin mainspar in place.  

5.  Elevate underside of sheeting at front and rear 

with scrap to conform with airfoil profile. 

 

6.  Omitting W1 glue wing ribs in position.  
7.  Glue 6mm strip to front of Mainspar 1mm from 

the top. Ensure that it is a snug fit between the 
ribs.

9.  Using guide lines on plan glue ribs in place. For 

the servo 
alignment. 

10.  Build second Wing. 
11. Trim and align root end of each wing panel. 

Note the mainspars are straight and not 
in either direction. Glue panels together. 

12.

16.  Place Sellotape along sheeting edges to collect 

surplus glue.  Tip: Do not try to align Sellotape 
with edge of sheet bu
with a sharp scalpel.  

17. Fit 1.5mm top sheeting taking care to ensure 

that it is making contact with both the wing ribs 
and the mainspar. Tip: Use masking tape to 
help support sheeting whilst glue sets

19. 

Carefully plane/sand both rear spar and 
leading edge to shape. 

Tip:

 when using David 

Plane set blade at slight angle so that the cut is 
thinner on one side of the plane. It helps 

king care to align tip end rib with 

control thickness of cut. 

20. Glue 0.8mm ply end ribs to balsa tips. Again 

there is a Left & Right! Roughly shape and glue

21.  Sand wing tips to shape.  
22.  Fit centre section trailing edge. 
23. Shape Ailerons and cut to length. At this sta

do not make allowance for 0.8mm ply ends. 

24. Tape ailerons in position us
