When I was reading through my December 11 kit plane magazine I came
across their 2012 kit aircraft directory where they give an overview
over all the airplane kits available today.

It just happened that I kept the December magazine from the previous two
years since I liked this compressed comparison. One really interesting
thing I found was that the Lancair IV changed its speed from 300 kts to
285 mph while the Evolution piston accelerated from 278 mph to 299 mph
over the three years.

I am really amazed by these marketing engineers and their ability to
beat the physics (e.g. designing an airplane with a bigger wing, bigger
cabin and higher empty weight and make it even fly faster)..... May be
someone can help me out since I don't have a degree in aircraft
aerodynamics.
