opening

1- Using a pencil, mark the center of the brace.
2- Trial fit the wing joiner into one of the wing panels. It should insert smoothly up to the center line marked above.
3- Slide the other wing half onto the dihedral brace until the wing panel meet. If the fit is over tight, it may be necessary to 
    lightly sand the dihedral brace.
4- Check for the correct dihedral angle.
5- Mix up some 30 minute epoxy and apply a generous amount of epoxy into the wing joiner cavity of one wing half.
6- Coat one half of the dihedral brace with epoxy up to the center line. Install the epoxy-coated side of the dihedral brace 
    into the wing joiner cavity up to the center line, marking sure that the “V” of the dihedral brace is positioned correctly
7- Do the same way with the other wing half. 
8- Carefully slide the wing halves together, ensuring that they are accurately aligned. Firmly press the two halves 
    together, allowing the excess epoxy to run out. Clean off the excess epoxy with paper towel and kerosene.

IMPORTANT:

Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol, only use 
kerosene to keep the colour of your model not fade.

1-Depending on the position of the linkage, determine the location of aileron control horn.
   The horn holes must be perfectly aligned with the axis of articulation.
2-Mark the position of the “foot” of the horn on the aileron. Then, with the drill, make the 2 

   holes.
