Blade Covering
Well, okay. But I've seen at least a half-dozen cases of cheap woodies (two Raptors and three Concept SRs with kit blades, one unknown set on a Nexus) covered with heat shrink that was lifting away from the upper surface of the blade under flight loads. In all cases, replacing the blades with glass or painted woodies eliminated the out-of-track condition without changing anything else.
