Well...
The most recent Patriot kit you have seen ( $100 bucks..) is a limited time production of the Patriot from Great Planes Manuf. They stopped making the kits and the ARF's a few years ago -- but they brought the kit back for a limited run. I wish they did the same for the ARF!!
These days the ARF's are pretty rare. Your best bet is either on here or E-Bay.
