I am really enjoying mine too. I had to add a lot of negative atv for inverted flight. I tried flying it inverted in the garage a few times and failed everytime, then on a clam day I tried it outside and found out that I didn't have enough negative pitch. I could flip it over and hover it inverted but, didn't have enough pitch to flip it back over. Wrecking this little bugger in the grass is better than concrete.
