The MD Helicopters MD Explorer is a light twin utility helicopter. Designed in the early 1990s by McDonnell Douglas Helicopter Systems, it is currently produced by MD Helicopters. There have been two models, the original MD 900, and its successor, the MD 902. The MD-902 is an enhanced version with Category A approval and powered by two Pratt & Whitney Canada PW206E or PW207E. Enhanced version has additional engine isolation features and changes to the Integrated Instrument Display System. Older helicopters (except for the first seven built) can be modified to the enhanced version. Original model by ztrztr (https://sketchfab.com/ztrztr)
