The general image we would like to portray in a logo is that of an ultralight type aircraft, under an inflated parachute canopy, being brought back down to the ground.
There are a few other companies in the world who make similar systems, and you can review a sample of their logos to get an idea of what we would to portray (although we do not want a logo that is too similar to any existing company's logo):
Also, our preference is a design that has somewhat of a 'classic' or 'retro' look to it.
No, having said all of that, we also realize that YOU are the folks who are professional designers, so let your imagination run wild. We will happily review everything submitted, and work with everyone making a submission to refine as necessary.
Thanks to each of you for your efforts. :-)
