i took mine to a professional builder yesterday......it has great detail....but cannot be considered an arf.......a lot of enginerring......you have to place all internal formers...with very little guidance.....the scale gear is awesome....if this was only thing i was doing with free time....i would build it my self.....but realtys set in...i have 2 full scales up for annuel inspection this month......maybe when i retire............sinc kpc
