I found an article on Nat Bast's Testors trainers in Flying Models Magazine, September 2003. I already have a Walt Musciano F-84 straight wing trainer (Clark Y airfoil) with a Fuji 15 and wanted a stunt trainer too. So the Sophomore 29 seemed perfect. I built one during the early time of the Wuhan China virus and put a McCoy Thunderbolt 35 with custom tongue muffler on it with a Zinger 10x6 2 blade wood propeller. I have over 10 flights on it now, but the 35 is too much engine so I am going to put an Enya 19 on it. Keep all of you informed.
