RE: McCoy diesels
My first diesel experience came from a beam mounted McCoy .049. When they came out I got both the diesel and glow versions. I had the diesel in a WOWEE flying wing.
Since I had never run a diesel, and did not know anyone who did, this was a learning engine. I ran it way over compressed and as a result, the lower conrod end suffered. As the conrod wore, I had to increase compression to keep it running. When it would no longer run with the compression at maximum setting, I retired the engine.
I was young and did not know about getting parts. My LHS did not stock engine parts so I would have needed to order them.
But I was hooked on diesels.
