Do the student rigs have throw outs or ripcords?
All BOC (bottom of container) throw out, I think we can safely classify main ripcords as being obsolete too. If you know of anyone using ripcord and spring loaded pilot chute main deployment, I would like to know and offer them tons of ripcords and pilot chutes. Of course, all our main and reserve parachutes are square, ram air type, most of the mains are State of the art Zero-Porosity fabric for optimum performance.
