Cutaway Bell Model 533 Helicopter developed by the Texas firm in 1962 based on an YUH-1B was extensively modified to set you two reactors J-60 derivatives Marbore, both had some inclination down and settled on the sides of the fuselage just in would be the area where the sliding door access to the cargo, its Plexiglas windshield verticalas reinforcements showed two separate one for each section of it, on the same floor supports are put to install two large swept wings reduced rope elongation and with some degree of positive impact, its rotor mast fairing was widely repositioning inlets now more aerodynamic, like the rear fuselage which was given a fairing as "Teardrop" and laterally extensive, stands for skates are also expanding the rope carefully careened thereof, all this allowed to increase the maximum speed reaching up to 410 Km / h according to some sources, others emphasize that reached the record of 509 Km / h, had great capacity closed at speeds of 320 km / h turn, then another model was built with engines more separate reaction by short wings, the rotor pitch of 2 to four blades, the more sorprendenete is that using this set of bladed rotor almost unchanged achieve these benefits, that if at enormous cost in fuel consumption when operating the three power units, Author Aviagraphica and modified by Motocar to recreate in a free interpretation prototype.
