RealFlight adds to the number of reasons why it's R/C's #1 flight simulator! Expansion Pack 4 software brings you 16 exciting aircraft and 4 amazingly realistic virtual flying sites.
  Enjoy a leisurely flight in the Upstar powered sailplane. Master intricate aerial maneuvers with the YAK 54 airplane. Or put yourself in the cockpit of the legendary B-25 Mitchell bomber while you complete military missions.
  No matter which model you choose, you can be sure that RealPhysics™ technology will have it responding just as it would in real life. And the detail of the aircraft is matched by the flying sites — from the “living” scenery of the 3D fields to the cutting-edge resolution of the PhotoField™ sites. It's the closest you can get to real R/C flying on your computer!
Compatible only with RealFlight G3 and above software.
