This simulator program is free on the Internet and you can download hundreds of airplanes, helicopyters, multi-engine, jets, biplanes, Extra, Cap 232, Super Cub, etc. You have to make a simple cable. I used Category 5 computer 6 foot cable, a DB-25 connector for the parallel port and a Din 6-pin for my Futaba 8UAP. Stuff to make the cable is about $10 or so. WELL worth the trouble to make the cable. With any experience at all, you can make this cable in a few minutes time. The name of the program is FLYING MODEL SIMULATOR. I can use 8 channels, my trims, exponential, etc. Not sure if this one has been covered, but I find it very helpful and wish I had downloaded it a long time ago! :-)
