Right, but I thought the idea of the original question was to see if sacrificing some good (higher than 300 foot tow?) might make cheap and safe possible. Seems like a small corner case until there are lots more FES, but still fun to think about. Agreed! It's a fun thought experiment for a growing sector of the sport. For me, the issue is that if I have a setup which can get me to 300', it can get me a lot higher for minimal extra effort. 300' would mean about 600' of linear space, which is unlikely to fit in the area before a runway. So once I'm using any part of the runway, I might was well use the entire length. The rule of thumb over here is that you get to 1/3 of the cable length, not 1/2, but it depends on wind too. Our Skylaunch (around 400 hp from V8 on LPG and 1000m (3270 ft) of cable gets me to 1200ft on a light breeze and 1400 ft plus in more normal summer weather with a reasonable wind gradient (Std Libelle, not pulling hard, so around 1/2.5 of line length on average. A low power winch won't do nearly as well. -- Martin | martin at Gregorie | gregorie dot org |
