I did a search and didn't get any hits on SeligSim, which is a fantastic RC plane flight simulator. And its free. I've been using it for the past couple weeks and it has vastly improved my flying skills as a recent new pilot

Check it out. Just google search. Unfortunately I just landed here and for some reason admins don't let newbies post URLs. NP

Note: When you fly you must choose a plane and a transmitter. You can also choose a flying site among several. There is a default transmitter already set up for each plane included in the simulator software. All you need to do is pick it and then use option to calibrate your own transmitter (connected via USB or wireless dongle, etc). There are "trainer" planes, warbirds, jets, 3D planes, sailplanes and high-wingers. There are also some "game" challenges. It's a great app. Check it out. Cheers
