Three months after Flyter was launched, the Russian company completed production of an early design model for its PAC VTOL aircraft in May 2018. This was the 15th iteration of a design that had been started back in the summer of 2017. This is the single-seat PAC VTOL 420-120 model—referring to its 420 kg (924 pound) maximum takeoff weight and 120 kg (264 pound) payload. By the end of 2018, the company completed the preliminary design of a two-seat PAC VTOL 720-200 model.
According to Flyter it is not primarily focused on the classic urban air mobility air taxi business model with its short flight segments. Instead, the company is more intent on meeting the needs of longer-range applications, such as connecting remote regions of Russia. The initial hybrid electric-powered version of the PAC VTOL aircraft is expected to have a range as far as just over 560 miles. An alternative electric-powered version would fly up to around 100 miles.
In November 2019, the company confirmed that it had begun ground testing of the downward-facing propellers and wing structures for the 720-200 model.
As of February 2020, Flyter was seeking the fresh investment it needs to recruit more engineering staff and build a flyable prototype. It indicated that it may first begin work on a trio of much smaller unmanned aerial vehicle based on the PAC VTOL designs. This, said the company, would require an initial investment of almost $250,000. It estimates that a further $950,000 would be needed to build a prototype of the 420-120 model and another $2.9 million for the 720-200.
