When it is 9 degrees outside or even 23 right now, one plays with the micro in the house. Not much of a micro pilot. Just too many things to keep track of in what I call super maximum manual mode. Maybe if the sticks were less sensitive they would be easier to fly. Well, anyway, I have it in a hover in front of me working on keeping it in the air and it manages to drop to the floor and skid to a corner. Pulled it out and took off. Instant flop over. OK, broke a prop. Check it, no, all OK. Take off, flop over. Well, something is not right. A real close look and this shows how something so small can make a difference. There was a small gob of dust wrapped around the base of a rotor. Cat fur! Darn cleaning person(me)missed that one. I took a loupe, small needle, and a tweezers to remove it. Took off just like it should. The smallest thing can make it not fly...... Now that you are completely bored, go read something intelligent.
