I have been flying glow engines for over fifty years. I haven't burned one up yet, although I did run my ST G21/46 hot enough to lose ring tension. That's the only time that I can recall. That's what I get for changing fuel types and then forgetting to reset the needle valve. It only cost me a new ring. Oh well.

If I came from model nitro car racing, maybe I would have the same or similar concern for overheating, but I don't. I do have an IR temp gauge, but I've never once used it on my model engines (all airplanes). No reason to do so. I hope that we can keep it that way. Don't create problems and worries where there are none.
