I wonder if your dad is "technically challenged" or thinks that Real Flight is just another video game. It's not. I've used mine a lot, I'm no spring chicken, (49) and it's saved me a few repairs. I've been working on rolling circles and flat spins. Can't get the sim to do a decent blender. My wife gave me mine for Christmas last year, along with a gift certificate. I think she's wonderful for thinking of my RC hobby.
