RE: .074 MARAUDER !!!
Joe, the wing-cam would give an interesting look..!
I might make up a set of 60 foot lines and head down to the control line area at our local airport to see how that goes. Flying this thing at 50 feet makes it seem like it's right there in your face.
Flying at 60 feet is riskier, I'm not sure how many 1/2A planes have tried it.
The was a guy back in the 1990s who flew a gigantic stunt ship with a TD.049 that was angled way out to the right...maybe 15 to 20 degrees..? The plane was extremely light for it's size and IIRC, he flew it on 60 foot lines and competed with it against .35-.40 sized planes in precision stunt.
What can happen with a plane that has marginal pull is it can cut across the circle with the lines going slack, then make a course correction that snaps the lines after it takes up the slack. So on a windy day, something like this is more prone to happen.
