engines on R/C buggy fuel, Nitro methane / oil mixture?
Sorry, no. R/C buggies today use glow plug engines. These run on a mix of methanol and oil, frequently with some percentage of nitro methane added as a go-fast ingredient. The ignition temperature for this fuel is much, much higher than that obtainable in compression ignition engines. You can comfortably place your fingers on the cooling fins of most diesel engines, like the “Deezil” for example, while they are running; you can’t do that with any glow motor I know of, not even the teeny-weenie ones. This shows just how much of a lower temperature the “diesel” mix burns at. That said, there have been rare, reported instances of glow engines starting through self-ignition. I was holding a U/C stunter with a Fox .35 in it that started like that accidentally–the battery was not even attached! But this is such a rare event, you could go through several lifetimes and never experience it. Question: Should I replace castor oil with modern synthetic oil?
