Nice gallery Dan and you are obviously into the cars and that is fine. You will find aircraft quite a bit differant and can be a little more challange and that makes it so very much more satisfying.
First to answer your question about the Zagi. While a nice flying bird and a lot of fun you will find it quite a bit faster flying airplane than what is normally considered a 'park flyer' but more important than that, what makes it a very poor choice as a trainer is the fact that it is a flying wing. A 'wing' is the most difficult airplane configuration of all to maintain orientation with That coupled with the fact it is fairly fast means you will tend to fly it to far away compouding the orientation problem. Orientation is probably the most difficult skill to learn for a new flyer and for this reason it is a poor choice.
If you want to start with electrics, fine but avoid all the barely controlled two control types that only have a directional control and an elevator function or in some cases instead of a elevator a throttle is substituted. Even worse are types that have two motors that are only controlled with collective power to try and control the up and down while steering by applying more power on one side. All of these things will be virtually useless if your goal is to fly an airplane. Only consider a model that provides three channels and a: Rudder, elevator and throttle consider nothing else. You will have lots of suggestions on this post as to specific types.
The Sim are good but its a differant real world out there so don,t let a sim fool you into thinking you can skip rungs on the learning ladder concerning airplane types. If you climb that ladder there will be a lot more satisfaction for you and a good chance this can turn into a lifetime obsession.
