This aircraft model is inspired by the design of the BAE 146, a four-engine, civilian passenger aircraft.

From Wikipedia...
The BAE 146 is a medium-sized commercial aircraft which was manufactured in the United Kingdom. Production ran from 1983 until 2002. Manufacture of the improved version known as the Avro RJ began in 1992. A further-improved version, the Avro RJX – with new engines – was announced in 1997, but only two prototypes and one production aircraft were built before production ceased in late 2001.

This aircraft has four turbofan jet engines mounted on pylons underneath the wings, and has retractable tricycle landing gear. The aircraft has a very quiet operation, and has been marketed under the name Whisperjet. It sees wide usage at small city-based airports. In its primary role it serves as a regional jet, short-haul airliner or regional airliner.

Product Features:
