Garry, you will find that there is quite a following for 'flying' card models. In fact, if you search about the forum for 'Ojimak', you'l find a designer who 1) likes his models to glide, 2) likes to share his stuff and 3) models are very nicely produced.
Check out this sample thread to get an idea...

I've found the forum to be a good group of folks and lots of fun. Hope you have the same experience!
