Thanks, Scale, that might be my next experiment. So far today I have tried using a spring that goes over the robart hinge on the tube (gets hung up coming in and out of the fuse), an elastic string, fishing line, and now a small magnet that is on the fuse, and a screw inside the aluminum tube of the tailhook to attract the magnet as the tube comes up and out of the fuse. But if the magnet idea doesn't work, I'll try fashioning a torsion spring as you suggest. Appreciate the input.

I was pleased that the tailhook came in and out of the fuse flawlessly on a number of tests. It just has to hang down without blowing back into the slipstream. I don't want to add weight to the tailhook, and I think if I did it by adding weight, it would have to be a LOT of weight to keep it down, but I'm just guessing at this point.
