Overair commits to Toray prepreg system for Butterfly

Toray's prepreg system is formulated for high-performance aerospace applications where the optimal ratio of strength to modulus properties is critical. It allows for autoclave and out-of-autoclave curing.

Hanwha commits investment and motors for Butterfly eVTOL

Investor Hanwha will also provide electric motors and battery packs for Overair's prototypes, as the two companies expand their R&D co-operation. First flight is planned for the second half of 2023.

Butterfly design promises high efficiency and quietness

Overair's engineers have emerged from the shadows and laid out plans for an innovative eVTOL aircraft, named Butterfly in recognition of its two sets of wings. Its relatively slow props should produce little noise.
