Well, not really, but my engine did yesterday I'm pretty sure! I have a previously abused Nobler ARF I am rehabbing and was test flying it yesterday and having some good results without the cowling on. I had 5 really nice flights and wanted one more before calling it a day, so got it started, launched and in the air to check my lap times, and heard a muffled pop, and the engine ran funny for about a lap, then sputtered and quit. i just called it a day and wound up lines and started to check out the airplane. I tried to restart it and it would fire, and it felt funny while flipping it. I pulled the spinner and found the prop nut loose. I drained the tank, checked the fuel filter and a few other things, then tried to get it to run on out a prime, and found the engine full of fuel! I pulled the glow plug, checked it and it glowed, and cleared the engine of fuel, put the plug back it and ran it dry. I put two ounces of fuel back in it, and it started and ran normally it seemed, but the exhaust residue was coming out brownish, where it had been clear. Went home and pulled the engine and took it apart, and found some brownish goo inside, but other wise the engine was like new inside. I came to the conclusion that I must have ingested a bug of some sort, and the engine ran long enough toe really liquify it's remains, and what was left came through when I test ran the engine!! Kind of like an airborne puree!! I have only ever seen this once, years ago at VSC when Gordon Dellaney was flying what I think was his original Too Much 2 twin stunter and one engine ingested a butterfly , made some outrageous sounds and quit!! I think all my engines will get a layer of panty hose to keep the critters out so this doesn't happen again and at the wrong time !!
Type at you later,
