My Aero Hawk will hover for only about 2 minutes. After that one ping pong ball is always touching the ground. I am running the 7 AAA 700mAh that came with it. The guy at the battery place I buy my batteries says I need to go to 2/3A 1100mAh. I think they seem to weigh a bit more than the AAAs and they will be rough to fit in there. What do I do to get this thing off the ground for a full 5 minutes??

Also can you give me a link on how to balance blades and the helo? Mine wobbles, and I am VERY GREEN to helos.

Thanks,
Todd
