My first plane was a Sig Kadet MkII built by me, flown by me, and destroyed by me all in the same month way back in 1986! It was a great trainer during the short time I had with it.
I recently bought a Sig Ryan STA kit on feeBay. They put a lot of extra scale stuff in them and apparently sold a bunch too. I'm looking forward to doing that one someday but I've always wondered why I have seen so few ever built? Somebody should do a build thread..
