All the vairiations of Cadets use the same wing tips. It is not rounded but is a flat rib glued all along the bottom and angled up and outward at roughly a 45 degree angle.

I have covered a ton of Cadet wings and what works for me it to use a small piece of covering and cover the underside of the tip then cut and seal the edges all the way around. In other words just the underside of the angled tip is now covered. The next step is to cover the bottom of one panel of the wing entirely with one piece then do the other. Next just turn over and doing one panel at a time cover from the center line all the way to the tip. Its flat even out to the tip.

Another method on the cadet wings and what I currently prefer to do is cover just the bottom of the tip ribs as above then with narrow (maybe six inchs) sheets cover just the sheeted inboard sections of the wing. Then do each of the four large open bay sections from the narrow inboard section all the way to the tips Forming a seam about a half inch from the edge of the balsa sheeting.
