[1][2][3] The Hurricane 103 and Ultra 103 designs are intended to have empty weights under 254 lb (115 kg) and fit into the US FAR 103 ultralight category.
[2][3] The Hurricane was originally developed as a clone of the Phantom X1 design by Jack Britton in the late 1980s and marketed under the name Avenger.
The aircraft was introduced to the market in 1991 and benefited from the end of production of the Phantom that same year.
As a result of the timing, the quality of the kits produced and the low price, the aircraft quickly achieved market success.
