Have flown the "airplane style" banner. Full bridal on a 600 foot line. Not the weighted style sling load shown in the video. It was 10,000 square feet (seriously!!). The static weight of the thing was 150 pounds. We flew around for at 40 to 50 knots all day long. A little tricky to land!! but rather uneventful. day 3, to burn some hours before a retorque...took it out with an AS350 (with a load cell). 40 knots equalled 400 to 500 pounds. 60 knots was almost 1000 lbs!! That was the end of the R44 days! The problem really lies in the winds and where you might divert to when you cant get home with a 10,000 foot sail. (i can see many of you thinking how big is 10K....80'x125' BIG!)
