I think all the reasons for resistance to diesels are listed her ein the various posts except 1. I don't know about you guys but for me, being a motor head, I just plain like to run diesels. I love the smell all acrid and nasty. I really am always amazed at the grunt of these engines...I love the old LLLOOONNNGGG strokers like the AHC diesel I just finished. I love tiny ones like the Bambi and I'm getting ready to built and ED Baby as soon as the casting shows up. I fly some CL and FF on diesel, but none throttled.
I guess for me I'm more interested in the engines themselves than their advantages vs disadvantages.
Long strokes bring a few of my engines to mind. I have some replica Mills diesels. All seem to run well. Another is one of my all-time favorites, a David Anderson twin stack .15 from the 1950's.
I don't have the tools nor knowledge to make my own engines...but that does not lessen my enjoyment of running them. Two diesels that appeared in model airplane mags with building instructions that I remember are the "MAN .09" (from Model Airplane News, mid/late 50's) and I think the other one was a "Dragon" which was a high school shop project - don't remember which mag.
