The manual seems set out very well at first look

Step 1: hinge the ailerons on ca hinges, then seal all hinge gaps.
It is stated in the manual sealing the aileron and elevator gaps is mandatory, as failing to do so will result in failure. It will give more responsive surfaces and removes the change of flutter so I guess it’s a good thing. No covering is supplied for this, and I reduced the width of the seal covering to 45mm. Manual says to start at 70mm then trim of
18mm

Step 2 : Joining the wing half’s . There is a diagram at the bottom of page 9 which shows 0 degrees dihedral at centre of the wing. It also demonstrates that when you are gluing the wing half’s to keep one wing tip hard on a flat surface and raise the other wing tip 1 1/8 “. I found when I did this the leading edge was not straight. To get it straight a placed a pin centre of the leading edge at each wing tip, then ran a peice of cotton between them. Marking center line at the middle of the wing allowed me to acheive a straight leading edge.
