Based on IST's iconic and military favorite F-1, the F4'swide blade design is slightly shorter however, there is no power shortage here. That s because of the expanded width rubber blade which incorporates unheard-of flexibility. Even more thrust is attained by 3 deep vents which force water backwards, emulating the effect of three synchronized turbo-powered water jets.
