The General Dynamics (now Lockheed Martin) F-16 Fighting Falcon is a multirole fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,500 aircraft have been built since production was approved in 1976. THE FMS molded foam construction shows lots of detail and a very smooth painted matte finish. Total assembly time is about one hour due to the low parts count and beautiful fit. The 70mm fan unit includes an OUTRUNNER motor that provides lots of thrust for quick takeoffs with a strong climb out. Access to the 70mm fan unit and 70A ESC is also very simple: just remove 2 screws and the entire middle section of the main duct can be removed. This is great for those who want to hop this one up or simply need easy access for maintenance and blade balancing.
