Elad:

When I said the smaller 4c engines were "Specialized," my meaning was that they require "Special consideration" due to their lower power to weight ratio, not that you had to be a specialist to use them. There are many smaller planes designed for the smaller 4c engines, and they fly very well.

But I really think you'll be happier with the 2c performance in your first several planes.

If you really want to go 4c do it. But do it knowing what you're going into.

However you proceed, it's a hobby, intended to be enjoyed, so use what pleases you. And yes, the 4c engines do sound better. Just wait until you hear a radial engine.

Bill.
