I am Mike Morley, my left arm is amputated near the shoulder. My square canopy is A PD Navigator , 280 ft sq. . The only " rigging" ever done was to tie A 1" square nylon lanyard to the left steering toggle. The lanyard has A good Petzel carabiner on the opposite end, which I hook onto the right toggle after opening and canopy check. This is used to take off brakes simultaneously and for landnding/braked turns. I go back and forth between toggles for ordinary play-around steering. Your situation is not that difficult really. Flying is learned over time, and becomes instinct. You can fly with your legs , there are no limitations if you don't care how " different" you look ! You will need your own rig , A DZ will not modify equipment to rent to you. The USPA IS a GOOD SOURCE OF GUIDANCE. Contact Sherry Buthcher, one of the National Diectors at 330-925-3483.....She can help you locate A willing AFF instructor. Persistance and determination are the only ingedients necessary !
