If you have $ for G2 (Great Planes Real Flight G2 ) get it and the interface cable to go with the radio you are going to buy. Get more radio than you think you will need. If JR wants to fly heli's you will need it. Using your own transmitter with the sim makes for more fun and way more realism. Flying models with my kid has been way cool, but don't bum out if he gets better than you! Kids pick up this stuff fast if they are interested.
