I´ve got both FS2002 and FS2004, I mainly use 2002 becouse it has better fps and I´ve got more add-ons in it. I wouldn´t say it would be good for RC flying but then again I´ve never tried to move up the simulation speed or anything

and also after starting first in RC sims then going into the MFS´s I feel like the extra is underpowered, can´t even do knife edges
