Hi Robert,
Yes, the Leo is flying fine. I currently have my 8S 5000mah pack as far aft as it will go (to the spar tube) and will be changing from a 16x10 to a 17x10 APC. For sport flying it is a dream. I tried some 'Sportsman' flying (first time) in our club contest and the wind was brutal. My only complaint is that I wanted a little more power...hence the prop change.
