Infinity's engine and prop-ring cage is made up of 1" diameter aluminum tubing with a 1/8" wall thickness. This superior design, coupled with Infinity's triangular cross-bracing, creates one of the strongest hoop-cages of any powered parachute aircraft being produced today.
Some of the other manufacturers use a larger diameter tube. Consequently, they have to settle for a much thinner wall thickness to allow them to properly bend the shape required to make their hoop-cages. This imperfect design, combined with little or no structural cross-bracing, may lack the strength necessary to avoid structural and/or propeller damage in the event of a roll-over or misdirected landing.
