This might take the cake....I was flying my first 110 I had about 3 years ago at a local street where a local truck driving company takes their students to practice parking, stopping, etc.....So im out there flying around and as usual I get a bright idea to further challenge my flying skills and land on the top of the tractor trailer as it goes by (they were only driving about 5-7 mph). I get her lined up and over the center of the trailer, get a little wobbly from the turbulence, lookin good and S**T!!!... outta gas. my little copter drops about 2 feet and lands on her side while being drivin away on an 18 wheeler.....needless to say I ran faster than I had in the 13 years since I graduated from highschool. Flagged them to a stop, explained what happened, appoligized profusely and got my baby back!
