I don't see how setting up dual rates could be hard for anyone, but who knows.

Well technically you could just set it up at a low rate to start, just like any plane. Then you would not need dual rates, but dual rates is what everyone advises. Wings are very pitch responsive. When you are cruising around, wings need very little elevator input because they are so short from stem to stern that a little does a lot.

Now, if you want to loop them and go into some aerobatics you can hit the higher rate and really go to town. But it isn't necessary.

While wings are not my first choice for trainers either, their one big plus is that Zagi wings, and many others, are made of EPP foam which makes them almost indestructable. I have bounced my slope glider wing, a Zagi 3C, 8 feet in the air. Then I brushed it and threw it back off the slope with no ill effects at all. So, what they lack in stability they make up in ruggedness.

One down side is that it can be extremely easy to lose orientation. Without that nose/tail configuration you can easily become confused as to direction and since they are so thin, at the right attitude they can seem to disappear for a moment if you are coming toward yourself near the ground.

However I still recommend high wing planes as first planes. And I usually recommend resiliant foam and plastics over wood, to try and keep the new guy away from the building table and heat guns.
