F-20 Tigershark RC Plane 50mm EDF Jet

The Northrop F-20 Tigershark was a super sleek, high-performance fighter from the 1980s. It was basically an upgraded, faster, and way more agile version of the classic F-5 Freedom Fighter, packing a powerful engine and killer handling. Even though it never made it into full production, it still looks like one of the coolest fighter jets ever made.

This model is best for you if you are an intermediate builder, and and have a well-tuned LW PLA, LW PLA-HT, LW ASA, or ASA Aero printing profile for your exact printer

This is a great performer with a solid thrust-to-weight ratio. The sleek, narrow wing means that it will need to be flown fast and landed fast, though it does land at a reasonable speed as seen in the flight videos.

If you are wanting a Tigershark with more aerobatic performance, included in the download are files for a version with aileron control, and not just elevons on the tail.

UPDATES:

7/8/2026: CG Mark moved 8mm rearward, giving a better starting CG. The previous position was quite nose heavy and required lots of back elevator trim to fly level
