>>1589108It’s not for dusting. Every pilot has hit a wire in their career.
My grandpa tore the top half of the vertical off once, started a fire and cut power to an area another time after clipping the wire with the prop.
You’ll go through the wire unless you hit a transmission line which are much thicker.
It’s the poles that cause the most risk.
There are knives all over the plane to help cut them.
