The dirty birdi was redesigned by Joe Bridi when it wasdistributed through G&S Hobbies. I'll know more, when my kit arrives. Picked one up off of Rcgroups for $60.00 + $20.00 shipping.
I was just about to put an order into Bluejay for their kit. $170.00 shipped to Canada.
The second picture of the plans are from the G&S kit (circa 2001), from another RCU build thread on the DB. These appear similar to the Bridiairplane plans.
