Covering Open Balsa Wing Structures With Shrink Film Without Warping Trailing Edges

A beautifully built balsa wing can be warped in minutes by careless shrink-film covering. In this video, I show how I cover lightweight open wing structures while keeping trailing edges straight and preventing unwanted twists. I explain how heat, film tension, temperature, and uneven shrinking can distort delicate balsa structures. I also demonstrate how I verify the wing geometry, attach and shrink the film progressively, support the intended alignment, detect developing twists, and make careful corrections without creating new problems.
