Hey, try X-Plane. It's a great Mac flight simulator where you can edit existing aircraft and build your own. It's easy, I taught myself and have built several RC planes. It actually includes two RC aircraft as default planes. There are also a few RC planes available for free download on the web, at www.xplanefreeware.net. Try http://www.tony.smiths.btinternet.co...aircraft1.html for all kinds of links to other aircraft. Go to www.x-plane.com to download the free demo version, available for Mac and Windows. I'm a Mac fan and really like this simulator.
