This bend looks way too tight for me, for 1/8" music wire upon which a 5- pound model airplane will land. I have visions of the thing snapping on landing, scuffing the hell out of one wing tip or another, and possibly making me cut into the (hopefully really nicely finished) top of the wing to push the remains out.
I can anticipate at least 500 flights on the thing, much of it off of grass.
What do y'all think? Bend new ones, or use what's in the kit?
