1/2a is a blast. I have a 30in wingspan free flight I converted to 4ch R/C powered with an AP .061 and am working on a 41in ws OS .10 powered right now. I have another kit on the shelf of a Jr Falcon reproduction kit made by a small company called Early RC run by an RCU member that goes by BobHH for a screen name. You may want to see what he has in the 1/2a forum.
