I can't think of any other explanation.
Within the next week or so, I intend to change the lipo wires to a thicker stranded wire, or I might even use a solid core wire. Either way, both of these changes will be better than using the thin stock stuff.
It's the stranded wire that makes it soft.
One solid core wire is stiff and not that flexible.
I think walkera saved some bucks on the copper quality in the wire therefore it's brittle.
Then amount of force when crimping is affecting same as how the wires are soldered and can create brittleness.
