As a slight side trip (but related) to this thread could the lines on a large control liner be longer than 70 foot just for sport flying? Correct me if I am wrong but I think 70' is the longest you can use in sanctioned events, so I am not talking that, just general sport flying.
I know line drag would go up (I bet a bunch) and that would quickly set a upper limit. But where (how long)?
There is a 1 to 1 line pull in #s ratio involved with the line length and also in model weight, i.e. double line length and halve the pull or halve the model weight and halve the pull. Speed has a lot more effect.
Just curious. I am not thinking of trying beyond 70' lines now, (or proposing that any else do so) but just wondering if it could be done and what the limits would be. A mental exercise if you would.
I do not own a flame suit so no
. Just curious to the practicable limits. The longest lines I have used and still own are 70s.
