This is the RealFlight Expansion Pack 7 from Great Planes. Compatible only with RealFlight G5 and above.

With Expansion Pack 7, you'll enjoy the richest variety of flying experiences that money can buy. ElectriFly ARFs offer you choices that range from the vintage Nieuport and outrageous VFO to the 100 mph Rifle! You can fly 3D with the AJ Slick, precision with the 94" span Aeroworks Ultimate 20-300 ARF and spy missions with the legendary SR-71 Blackbird. Try out Curtis Youngblood's Rave 450, the tiny, Novus 125 RTF, the all-foam Paper Airplane - and you'll still have eight aircraft adventures ahead. As always, the flight performance is unsurpassed…and some airplanes not only feature detailed cockpits, but moving controls as well.

In addition to 17 aircraft, there are also three new flying sites to explore. On the Alaska Float Fly site, you can marvel at natural wonders reproduced in crisp, PhotoField detail. Go to the 3D Area 81 Obstacle Course, and you can test your flying skills. Go to the single-player 3D Barnyard Shooting Gallery, and you can practice your marksmanship for fun...or the next G5 combat event.

Expansion Pack 7 packs infinite possibilities on a single disk, and presents them on "The most realistic recreation of R/C Flight ever": Great Planes RealFlight!
