I'm trying to find a download for the Quad City Challenger II created by Bill Lyons.
Apparently he's taken the summer off so his download pages aren't working.
I'd be happy to pay any download fees.
Your right the link is dead. Since it's pay-ware his site is the only one (I imagine) that you can get it from.
No download, no key number, sorry but you'll have to wait, e-mail him
There are quite a few ultrlights available free at www.flightsim.com try some of them until you can get his.
Here are a few from avsim.
