I bought the RealFlight 4.5.  They now have the 5.0 version out.  I love it.  I have been flying off and on more a few years before I bought it.  I have alsoworked in a/c maintenance for 31 years and I have been in a few airline sims.  The RealFlight is as close as I have seen to real r/c flight on a pc.  The controller cannot be changed to sim a specific brand.  But it is a typical flight controller.  It has flap and retract capability.  I highly recommend it.
