I get maybe 5-6 minutes of hard flying,loops,rolls, fast and slow piroettes after a 2.5 hr charge, as soon as I hear the blades working harder...its time to land...I will be getting the aerobatic upgrade next week with a couple of TP1320`s...this little bird is too much fun!!! I like that it can all be done in my backyard or garage if its too windy.
