There are no young kids that would come in contact with anything helicopter in this house. There aren't any kids, period. I checked the batteries and there isn't anything wrong with them. My theory is, the controller was lying around, untouched (because I crashed my helicopter, got mad, and stopped doing anything helicopter for a month and a half but now I'm happy the fix was only $20 and very simple to do.) and the lubrication kind of "settled" so, when I picked it up again, the friction and movement made a bubble that ruptured with great vibration, producing a fart noise.[&:]

P.S. Nothing is fried or frayed or anything like that inside.
