I used to do r/c hand-launched sailplanes and winch/hi-start launched larger sailplanes.
one afternoon, in a crankin wind, the line release on the 'Legend' sailplane failed.. too much pressure on the release. i inadvertently wound up with a three-meter 'kite' hung up at 300' on the end of the winch line.. with full r/c controls.
At first, i was wrestling with it.. almost tore the wings off it till i got it trimmed down enough.. then I had a blast for an hour doin some really wild and crazy stuff with that big monster.. imagine an 80 ounce kite 'tacking' back and forth, to the point of draggin a 40 pound winch around in the 20 knot breeze. Awsome.
Next week a freind and i showed up with a pair of Sig 'Ninja' slope-soarers with a tow releases mounted in 'em. Ran 'em up on a simple hi-start, but stayed 'on' the tow lines. Was some really sick toejam.... R/C Kite-Combat. Some of the most fun I've ever had with r/c sailplanes.
