What kinds of things have you seen get sucked into the mouth of a hungry model jet? I was test running an EDF (HET F-18) on a workbench to get some amperage readings when my electricity bill, lying about two feet away on top of the envelope it came in, slowly slid over and then leapt into the intake! Instant confetti and a groaning sound not unlike a chipper/shredder! But it didn't seem to hurt anything- Just lucky, I guess. It's had a rough life since then. How about your hungry jet- EDF, Nitro, or lamp oil burner? Dinner, anyone?
