Once one gets familiar with a diesel's operation, it like everything else in the hobby becomes second nature and you dont really think about it. I have had a glow engine with a three needle carb (OS 61 SXWC heli engine) that I ran for two years in one of my helis, I found adjusting three needles no more trouble than two or one
It all comes down to an individual preferance. I like running engines, ALL engines, and diesels to me are worth the "trouble" for me. For someone else, maybe not.
But I still like to let someone try something first and then make the descision, rather than just base it on someone elses opinion.
I dont like certain things in the hobby, so I dont participate (gliders for instance). But I at least had two, gave them a try and now I can say that I made the descision, not my buddy who told me they are "boring". (that s but one example, please dont take it persoanlly if you indeed like gliders).
My point is, TRY one and then, only then, make your decisions. And if you decided that diesels are too much trouble, no benefit, a pain in the *** or just too expensive, well, thats perfectly allright!

We do live in countries here with free choice.
