aerospot:

Did you watch the video today? The video server has been down for past few days.
As for the sim, yes it is aeroflypro. Since your grandson is of video game age, I imagine he will be most interested in 3D flying. For this, nothing can touch aeroflypro. Most of the flegeling aerobatic pilots at my field converted to aeroflypro from realflight g2 and g3 for its superior 3d flying capability.
