Aero Fly Deluxe. IMO Bar none the best RC simulator on the market. Tons of free planes to download off of 3rd party internet sites. Planes are fully customizable. 3D flight physics are top notch. Some may argue that Reflex is better. IMO no way the grapics my be but noting noticable. ANd as far ans the flight characteristics go AFD has Reflex by a mile. Ands anyone that recomends G3 is trying to sell you theirs because its trash. LOL. I dont care for G3 in the least. I believe $ 179 on ohio models website search simulators. That comes with a transmitter too.
