I've built a 122 with D-jet. It's a great novelty and generally runs well, but was really more work than it was worth. I should have built something really fast for all that effort. Perhaps once it's sorted and running at its best I'll feel differently, but all I can do is kick myself for not putting in a B23FT or a V8 or something like that. I still love it, though, even if it's not the fastest.

PS. The pic was the first time the engine ever fired up. Literally. What you can't see in the picture is my jumping around like a giddy child. That was a good day, for sure.
