Use the wire from a piano hinge. It is strong and will make a great spring.This is what P.F. Beck used and it works great.-----Original Message-----

I don't get it. I have a dog named Turtle and three bunny rabbits, so Ifigured this would be the ideal way to get the whole family involved in theairplane stuff. I tried gluing the dog to a wire and hanging her outside thecar, but at all speeds between 20 and 80mph where this thing's supposed towork, she kept wiggling and carrying on so much that I just couldn't get anygood readings. The rabbits were even worse, their ears just flopped so muchat 60mph that the instrument almost blew itself apart. Now neither the dognor the rabbits will have anything to do with me. Do I need a real turtleand a genuine hare for this contraption? Could there be something else thatI'm doing wrong?Mike Whaley merlin@ov-10bronco.netWebmaster, OV-10 Bronco Associationhttp://www.ov-10bronco.net/___________________ ... __________
