This new version of the FMS F4 has a new larger and more powerful 2845-3000Kv motor, 8 blade fan, 70A ESC, and runs on a 4S 2200 LiPo. The new FMS F4 retains the fixed landing gear which provides a durable foundation for this scale EDF jet and helps keep the price affordable. The F4 landing gear can be removed and be replaced in a matter of seconds for those who prefer hand launching and belly landing when the situation calls for it. This plane has the looks and sounds, and is a blast to fly!
