There's a company in Au that makes a Chipmunk, Model Design. http://www.modeldesign.com.au/SuperChipmunk.html It looks good in the pictures. 100" wing span. It looks like you could buy the Austrailian 100" fiberglass plane sheeted for the same price as the Apache kit and no shipping.

Make sure you add weight to the counter balance of the rudder and elevator to prevent flutter. The surfaces are pretty big, it will not take much weight. Ohio R/C recommended scrap piano wire near the leading edge of the rudder counter balance. I heard that a 3W chipmunk went in because the tail fluttered and the tail ripped off the fuselage down in South America.
