This is the E-flite Ultra-Micro UMX F4U Corsair Ready to Fly Electric Airplane. With a top speed of well over 400 mph, the gull-winged F4U Corsair was one of the fastest planes of World War II. This speed, combined with awesome firepower made it an incredible opponent in air-to-air combat, as well as one of the most fearsome ground attack fighters of its day. It could strike suddenly and without warning, leaving a ghostly howl in its wake that earned it the name "Whistling Death" among ground troops unfortunate enough to feel its sting.

This exciting UMX™ series replica of the F4U Corsair features advanced AS3X® (Artificial Stabilization - 3-aXis) technology that works behind the scenes to smooth out the effects of forces like P-factor, turbulence and torque. Instead of an ultra micro, you’ll feel like you’re at the controls of an expertly tuned, giant-scale model that flies like it’s on rails. Best of all, it feels completely natural. There is no delay in control response or limits on the control throws. You’ll simply feel like you’re flying an expertly-tuned, giant-scale model that’s incredibly stable at every speed.

Built to Victory Roll
Each aileron features a Spektrum™ performance linear long throw offset servo for precise control that makes roll maneuvers as axial as possible.

Big on Detail
Scale detail like an authentic paint scheme, clear canopy and molded panel lines make this ultra micro easy to appreciate. Decals are provided to finish your model as either the ace Corsair flown by Gregory "Pappy" Boyington or Ira "Ike" Kepford.

Power and Control
This UMX™ F4U Corsair comes with a high-performance 3-bladed prop and tail wheel steering for great handling in the air and on the ground. You can even remove the landing gear for a more realistic look in flight.
