My estimate of the proposed rules.
Rule 1 : You must use the NACRA I-17 platform
Rule 2 : you may use NACRA F18 rudderblades as an alternative to I-17 rudders (which are actually the old Nacra F18 rudders)
Rule 3 : Everything must be bought from Nacra
Rule 4 : Big guys may use a standard Nacra 21 sq. mtr. spi (also known as a nacra F18 spi) instead of the standard Nacra 17 sq. mtr. spi.
Rule 5 : everything else is prohibited.
Due to overwhelming demand this class will come into effect as soon as somewhere in 2005.
Same I-17 platform really just with a new catchy name.
Some formula class !
