Relatively new bird with no real crashes and both original batteries were not providing even 2 minutes of flight time so I bought 2 new 480 mah fro Wowhobbies. These batteries did not provide even 2 min of flight time either, so I replaced the main motor. Still has low poser for a short time. Out of the box I got a consistent 5-6 minutes with good power. Anyone experience similar or have any ideas? Thanks!
