So I heated up the twisted wing tip with two hair dryers (one on each side) and applied some careful manual force. To plank the wing is easy with contact adhesive but once stick, you cannot move/correct the parts anymore! This resulted in a slightly twisted wing in my case. Test the deflection of your wing before and after laminating. To stiffen the structure of the wing (force path between landing gear and fuselage) I have laminated further "magic black hair" (carbon fiber roving) in DIAGONAL orientation. Instead of carbon fiber tubes I used carbon fiber profiles of 6x0.5mm which are lighter, cheaper and stronger. W2 is partially made of ply wood to accommodate the retract landing gear. The order of profiles of my wing is from center to outboard: W1, W0, W2, W2 (yes twice), W3 etc. Need your own NACA? Search in the net for "NACA Generator" and scale it to your needs. The following instruction is about the wing building. As I wanted a curved wing with retractable landing gear, I started from scratch and designed my own one.
