Also one of the very few "build from scratch" aircraft that don't have winglets...
It doesn't need them, the wingtips 'appear' to be slightly raked. Winglets can be a hassle high crosswind landing conditions at PC12 speeds, particularly the large ones.
The aircraft appears to the be a natural progression from the PC-12 although the 'single is best' mantra won't ring true anymore.
The wing will have to be pretty well designed, short field work, 425Kts (true) and 1900NM+
