Hi. I didn't buy/build any plane as of now, I only want to use a simulator (just out of curiosity  ). So just becuase it's curiosity, I've googled "free RC simulator download" and I found this brothersoft link : http://games.brothersoft.com/clearview-rc-flight-simulator.html
. Do you guys recommend it? Atleast for a beginner like me? What do you say? Thanks!

Try FMS as it is Free in true sense

You need a Analog Joystick minimum for 200/- appx.
And FMS. Some adjustment in settings of FMS about control after selecting Analogue joystick.

If required, see tute in youtube for settings.

And Settings => Model uncrushable so that you can learn not to crash initially.
