Default Tow Plane Upsets......

The Pawnees at Turf Soaring had a 337 mod to invert the Schweizer releases. In theory that would work on a kiting situation, since the pull force would be on the fixed arm so the release arm would be free to move.

But that begs the question of the glider end - if a 1-26 or 2-33 kites, now HIS release is under tension, so HE can't release! A truly poor design, IMO.

Probably the best solution is the TOST internal reel with the guillotine - we checked ours on the ground (at rope replacement time) and even with relatively little tension on the rope (compared to a kiting glider), the guillotine (lever right in front of the throttle in the Pawnee) cut the rope like a piece of spaghetti. Actually surprised us how easy it was! And enough to convince us to install the same system on our other Pawnee, replacing the POS Schweizer release.
