F-20 Tigershark
Ducted fan speed, sport-scale style.

To prevent front-line fighter technology from falling into the wrong hands, the U.S. Department of Defense launched a project in the late 1970s that would produce less advanced aircraft for sale to our allies.

Approximately $1.2 billion was spent by Northrop developing the F-20. But when policy changes during the Reagan administration left it competing directly for sales with the superior F-16, the project was abandoned. Just three prototypes had been built — and only one survives.

Still, the F-20's speed and aggressive lines captured the hearts of military aircraft enthusiasts — and of like-minded R/C modelers, who'll find plenty of both available in this ElectriFly EDF.

  • Includes HyperFlow™ ducted fan unit with powerful Ammo™ 24-45-3790 inrunner brushless motor.

  • Strong, lightweight AeroCell™ foam construction.

  • Fast, easy assembly.

Rx-R™ features preinstalled electronics!

The HyperFlow™ ducted fan unit, powerful Ammo™ inrunner brushless motor, Silver Series 45A brushless ESC and 3 micro servos are installed at the factory so you can be flight-ready in just a few minutes

About the HyperFlow™
Ducted Fan Unit.


The HyperFlow ducted fan unit was designed by our engineering department using flow analysis and state-of-the-art computer modeling to identify the parameters for high performance. The result is the ultimate ducted fan design.

With the HyperFlow and our efficient Ammo 24-45-3790 brushless motor, the F-20 is primed for hyper speeds!

Molded from advanced AeroCell™ foam!

Tough enough to take abuse — light enough for electric flight — and factory-finished for stunning presence in the sky!

The AeroCell Advantage

AeroCell may be the finest material ever created for electric aircraft! This closed-cell foam delivers the benefits of costly composite construction in a more pilot-friendly, easy building form. AeroCell offers the structural strength and rigidity of traditional structures without building...the weight advantages of foam without the brittleness and breakage...and a paintable surface that comes out of the box factory-finished.

parts layout
Assembly of the F-20 Tigershark can be completed in as little as 4 to 6 hours. As with all ElectriFly models, a complete package of high-quality hardware is included. 


The AeroCell™ surface comes already finished in high-visibility colors. Decals and removable magnetic wingtip missiles are included. When you can't be out performing rocketing climbs and high-speed passes, admire your F-20 on its included display stand!


ailerons & linkages
The F-20's aileron and elevator control surfaces have been hinged at the factory to reduce final assembly time.


spacer hatch
The detailed, magnetically secured canopy hatch removes easily for access to the F-20's battery compartment.


brushless motor
The HyperFlow ducted fan and Ammo brushless motor combination produces impressive thrust and speed.


spacer air intake and rear exhaust
Optimized air intake and exhaust areas contribute more than exciting realism — they help draw maximum speed from the F-20's HyperFlow ducted fan system.


Only one full-size F-20 Tigershark remains of the three built and tested in the early 1980s. ElectriFly brings the experimental jet back to life with exciting sport-scale looks and blistering ducted fan performance.
