RealFlight Expasion Pack 6 Every opportunity for adventure is inside. All you have to do is seize one. They stretch from a tiny, 7.5" span indoor flyer to the Convair Sea Dart — the only seaplane ever to break the sound barrier. Power options range from electric nano helis to glow- or electric-sport planes to gas-powered giants. And aircraft choices include all of the above, plus a .90 glow heli, the world's first jet fighter, a delta-winged "bullet" and a rotary-wing fighter with gear-mounted cannon. There are 18 aircraft choices in all, plus three new flying sites. You can fly the 3D Water Park/Obstacle Course by day or night or explore the Silverton Prairie or Jefferson Airstrip PhotoField™ sites. And with the aircraft choices and flying sites included in Expansion Pack 6, you also get two incredible bonuses. The first is a free upgrade to G4.5 for G4 owners. The second is access to all 24 flying sites and all 70 aircraft choices originally included on RealFlight Add-Ons Volumes 1-5! It's the most value-packed Expansion Pack to date — and a natural companion to "The most realistic recreation of R/C flight ever" — Great Planes RealFlight!
