The plane is then flown at the wire at Vne. Then its pulled into a sharp climb and max power. They want it to be a steep as possible so the banner pulls clean and no twists etc. If that happens they have to drop it and start again.
Yep, bent the main spar on a Super Cub, year 2000. Someone had wrapped the wire twice round the pole
, so when max applied, guess what, out came the poles as well. They fell off as climbed away, continued with the banner, now unfurled, and after landing, the aircraft was checked. Main spar bent, mmmmmmm...
Always thought had it been a standard Cub, might not have made it. A loop at 75 feet
