You could also have a look at this one I found on the web
http://www.62ndfightingfalcons.asn.au/62ndff/projects/cockpit/cockpit.htmThey have an excellent set of plans to download and I am sure you could pull it off for less than $300 not including the Joy Stick
They ask that you email the designer before you build which I don't think is to much to ask, mind you they are the email addresses may no longer be valid as the plans are from 1999
I actually thought that the 62ndfightingfalcons were an AH squad but I cant find them in the squad list maybe I missed it
