I went to the Lebanon PA flea market yesterday. I saw enough used glow engines for sale to keep us all flying glow for several generations to come.


I was also there and concur that there were more used engines there that have been available for quite awhile. The tragedy is that as always about 75% of the engines were really a bad investment. It's incredible how badly people treat their engines. Perhaps that is why electric has such a hold. You really do not have to know anything other than how to plug the components together and how to turn operate the switch without screwing it up..
Also why would someone bring an engine in looking like it had been used in an explosive device and then say that it had hardly been used. Perhaps it is overdue to give intricate devices that require some level of intuitive knowledge the rest that they deserve.
And I agree that the prices of things like fuel and even props and glow plugs could become very expensive and difficult to obtain in a world that no longer embraces carbon burning engines.
