Kasetsart University
The Faculty of Engineering at Kasetsart University, Bangkok assembled two Rotorway Exec 90 helicopter kits for a private individual in 1988, and evaluated them for agricultural and other uses. In the early 1990’s at least five other Exec 90 kits were imported, and these were assembled by the newly-formed Department of Aerospace Engineering. The aircraft were allocated ‘serials’ in the form 0734-005 where 07 shows month of construction 07 (=July) and year 34 (=1991), and 005 is a sequence number. Known details are:-
????-001	One of initial kits assembled by Kasetsart University. No further details.
