Hello,
I am interested in trying flying RC's but would like to test my interest on a flight simulator...
Do you know of any free software?

FMS http://n.ethz.ch/student/mmoeller/fms/index_e.html

it's for windows though [&o] so if you have a mac, forget about it.

yeah, I got FMS too... Its free! I also got a lot of extra planes for it, more then I'll ever use I'm sure.

where did you gert the planes?

The planes can be found all over the web.
Just do a search for FMS and you should find a buch of sites.

Do I need a radio to use this or can you use a game controller???

You can use a game controller, joystick, or keyboard. Best to use radio.
