I was referring to all of them. I have no time for them. I'm pleased to hear your results are different. I have never found them to be powerful, easy starting or worth using.I certainly appreciate your expertise and by no means do I want to be in a bickering match of what is better. I have a real passion for all engines from vintage to high end engines just no desire for the Mccoy or Testor's AMF engines. The CG issue on my plane has been resolved and tomorrow I might get to fly it so I'm looking forward to it. Ken

IMO, the front reed valve Testors / Wen Mac .049's with the right glow head were at best Babe Bee power. There is also the Wen Mac Hot Shot, that seemed to be better, but never had one. Here's the power curve of the last one I bought new some 30 years ago.

I liked them because they were easy starting.
They were for a kinder, gentler time. Laughing Tired w/ Coffee Read Popcorn lol!

At age 16 I built and flew a Sig Witch Doctor X (Jim Clem mid-sixties contest F/F design 54" w.s. for Tee Dee .049/151) with exactly the same engine GG posted-- tank, starter and all screwed to nose block with Wen-Mack 6-4 nylon prop; I just hooked fuel line to an eyedropper rubber banded to nose block. I used Fox Missle Mist fuel. Now I'm not going to make any wild claims that it had a climb like a well tuned Tee-Dee set up at the Nationals back in the day, but I can say with confidence that the stock Testor-Mac FRV engine hauled the freight as good as any stock Medallion .049 on same fuel. I was no expert builder of F/F models either (and still not one to this day).
