I don't agree about the neckstrap being dangerous. Everything is dangerous in this hobby if zero care is taken. We had an accomplished pilot this past weekend accidentally run up his electric and it cut his finger nicely. So remember nothing is safe in this hobby. That said once your shakes are gone, probably in two or three months you'll long for them to return. Its a weird feeling this hobby gives you and that's one of the more irresistible things about it.

I also do not agree that going quiet is the way to go. If that's the case it would be better and cheaper to buy a simulator and fly virtual. Sound has alot of pluses. It allows you to hear how you're engine is fairing relative to the air. It is also more dynamic than gliders and powered flight has a bigger upside than any other flight technique.

However, I do think gliders teach a very important aspect of flying and that is the stall technique. Though I would hardly tell a beginner to start off learning this technique, it is invaluable at later stages in flight, primarily warbirds.
