#7 Has some potential. Aircraft profile needs to look more like a real experimental aircraft, not a production jet. See the websites on the general comments for what I'm talking about. Most all experimentals are propeller driven with straight wings and a much stubbier look. Engine - or whatever you use in the background can't come from a car. Needs to be something aviation related, or more abstract.
- changed the font, now its more easy to read - the slogan is bigger - with more kick - the aircraft in bordeaux´red with a small shadow, thats the adventure part
I think I like the first version of the text better. I do like the airplane illustration. Can you try it with a visible prop and cowl instead of an opaque circle?
