Got to agree with Ken. Learning how to repair and what to repair is a big part of this hobby. He will be a better pilot learning how to get the plane back in the air, and learning what not to ignore in the process. Flight simulators are great for flying skills I guess, but the results of a bad move are only a restart away. If you keep making the repairs for him, you're just providing him with a slow restart to the simulator. He needs to learn how the plane is built and how to repair the results of his mistakes. The simulator provides a video game environment where the good guys kill all the bad guys and all is well. Well the plane flies and lands and all is well, but it doesn't provide the overall reason why the plane flies and why things need to be balanced and aoa and thrust, and the list goes on.. Teaching him how to repair is filling that void. Teaching him to build completely closes the void.

A good instructor teaches more than how to fly. They teach why it flies.
