Ahhh .... fond memories

I still have a couple of McCoy red head 35 stunt engines that I keep for the memories. Back then, I would just keep swapping them into whatever I was flying (and crashing)at the time. I don't know how much fuel was run through them. I didn't keep track of how much fuel and how many starter batteries (remember those?) I bought just to keep flying. They never gave me any problem or wore out. But they sure gave me a lot of fun - and are probably the reason I'm flying RC planes today.
In my book that made them good engines.
