The other day I stoped to watch a guy fly his foam ducted fan jet. He stared to get out of control due to trim issues and it augered in from pretty high up. I heard the crash and then there was gray smoke. This was just like the real thing. Then there was black smoke and lots of it. We had to drive around the field to get to it. By the time we got there maybe 5 minutes there was just the outline of the jet on the ground. It was completely burnt up. There was a pile of burnt wire and part of a wing, thats all. I felt sorry for the guy, but it was cool to see.
