XTI TriFan 600 Orderbook Grows With Brazil Sale While the hype is there for fully electric and hybrid-electric airplanes, most of these efforts by companies is on the smaller scale. Right now XTI is working on a VTOL (Vertical Take Off and Landing) aircraft which has been in the works for a while, since 2013. To bring it to market is the hard part as this long development and then certification phases is extremely costly. The hype is there so far with 60-plus orders for their XTI Trifan 600. Recently an order came in from Brazil for an XTI TriFan 600.
