I've been doing it for 48 years, but the amount of years doesn't necessarily equate to the quality of build and repairs. I've seen some with only a few years experience really turn out nice results.

Agreed.

Going back to the original poster, there are always repairs that someone who is inexperienced can do, with basic adhesives such as epoxy and carpenter's glue for foam, plastic packaging tape, scrap Styrofoam, plywood, etc. The more difficult repairs might provide a challenge beyond their abilities, but there is a certain self satisfaction when one accomplishes a repair that allows them to continue flying the same model.
