Fuselage mold question...

Since this is 17 long fuselage and i will be making kits to sell, how many sections should it be to make it's molds, keeping in consideration that if anyone needs any sections replaced due to damage or crash could just get section to rebuild his model. Presently it's on 4 large sections including nose and visor, if nose and visor are separated to make there own molds, well then it's 6 pce fuselage presently.

I want to use this fuselage for my prototype flying as well as use as plug afterwards to make molds on it.

Wings and fin will be 2pcs molds each and nacelles could 1pc or 2pcs also.....


Thomas any suggestions or others who does commercial molds for giant model aircrafts...


Plus what other things should be considered or i should consider while making commercial kits of this beast!....
