For $40 you can download Clearview RC flight simulator. I also bought a USB adaptor on line for $10 that works on a variety of transmitters, mine is a JR.783. I also tried with an old Futaba super 7, and a JR 9303, Any transm itter that can modulate PPM (FM 72Mhz) i think will work with this cord. I own G2 and G3.5 but, I like how the whole display zooms out in Clearvie w so that you still have a good perspective of where the ground is. I feel the makers of Clearview got that part of realism better that all of the res t of the BIG MONEY rc simulators out there!!! It has fair graphics and the control response is good enough to learn to fly. I downloaded a bunch of th e user models and am pleasantly suprised by how well some of them were like the real thing... I am an RC airplane pilot of over 25 years and have competed on a national level. I only endorse the program because I like it. I have no assosiation with Clearview in any way othar than, I use their software and have tried many others and feel it's a graet learning tool at a reasonable price for s omeone who has their own FM transmitter and wants or needs simulator practi ce. I used Clearview this past year to learn how to fly rc helicopters, not to brag, but after many hours of training on Cleaview I finally went to the f ield with my Trex 450 and flew 12 flights with training gear without incide nt over a few days. Then I got confident enough to take off the training ge ar and go full idle up and in stunt mode. I didn't have any incidents till my 19th flight while practicing some 3D meneuvers. (in the rc heli flight w orld that's impressive so i've been told). So for those of you out there who want the cheapest way into RC sims and own an FM transmitter I would seriously consider Clearview. Hope this helps! Ray
