It sure looks like most of the purchasing decisions are strongly influenced by:
1. Color or color scheme.
2. What is a hopefully impressive decision
3. Which "hero of the hour" , is flying one.

This all makes sense as these factors are used in determining the advertising for the products.

Developing your skills based on purchasing a plane acquired by following the above influences - makes little sense to me.

Tho it ain't impressive - what really matters for developing good flying skills is a far less expensive approach:
buy the most power to weight setup with the lowest wing loading - -even if you have to ( choke) actually do some building/ rebuilding work on it.
Size does not really matter all that much at his point.
